General Tactics

The Idoneth Deepkin are a faction which sees GW re-envision sea elves for the Age of Sigmar setting. Tragically lacking souls (so they've come to steal yours), the Idoneth are an army that rewards careful placement of models, a variety of units that provide rapid mobility and negative modifier shenanigans and some of the best allegiance abilities in the game.

Why play Idoneth Deepkin?[edit]

They are elves unique to AoS, and a rare example of sea elves with fleshed out lore and playstyle.

For more points:



  • You're one of the only two armies with a Battletome from AoS FIRST EDITION, so... two editions behind at the moment, and with 3E shaking up things AND some of the original warscrolls outdated on the Battletome... yikes.
  • Namarti are quite fragile.
  • Their bravery is mediocre, and they mostly lack the high wounds count or saves to take the lumps and keep going unlike their equivalents in other armies.
  • Mediocre spellcasting unless you shell out the points (and a lot of money) for an expensive Eidolon of the Sea.
  • Your army is mostly monobuild; you will not have a competitive list without the eel riders.


Faction rules and abilities: Battletome Idoneth Deepkin

Latest Matched play points: Generals Handbook 2020

Core rules: here

Matched play rules, battleplans and expansions: General's Handbook 2021, plus the battleplans from the Core Book.

Supplement all the above with any Errata and Designers' Commentary from the FAQs.

The Idoneth Deepkin Battletome was released in April of 2018, and as such, this is the second-oldest active Battletome and thus relatively due for an update (only Maggotkin of Nurgle predates this one). That said, it was also the last new battletome released before AOS 2.0, so they very likely had the upcoming game changes in mind when designing this book. It's gotten to the point that the third edition of AOS came out and they still haven't gotten a new battletome.

Allegiance Abilities[edit]

Battle Traits[edit]

  • Forgotten Nightmares: Your Idoneth Deepkin units can only be targeted with Missile Weapons if they are the closest visible target. Keeps your Heroes safe from shooting, though not from magic. Also note that you can use allies to shield your Deepkin with this as the rule stated that the Deepkin unit must be the closest unit. If there are no Deepkin units in range, then the attack must hit the non-Deepkin unit.
  • Tides of Death: Each round, you get a different ability. After the fourth, it cycles back to 1.
    1. Low Tide: Your units count as being in cover. Helps you advance without making you scramble to terrain.
    2. Flood Tide: After running, your units can either shoot or charge (but not both).
    3. High Tide: Units with this trait fight before everyone else in melee At the start of the combat phase now. Get Shipwrecked, Gristlegore. Also, there's a bunch of abilities that activate during this turn.
    4. Ebb Tide: After falling back, your units can either shoot or charge (but not both).
    • It's worth noting here that there are two alternate army list choices that can be made to alter this sequence's order (including taking both together for a third option):
      • reversed order (via Tidecaster as General)
      • Ebb replaced with Flood Tides (via the Fuethán enclave)
      • both options (meeting both conditions)
  • The Ethersea: You get to place up to two Etheric Vortex terrain pieces. Currently, the only existing Etheric Vortex terrain piece is the Gloomtide Shipwreck, which you can either split into two or buy and place two full ships of. The shipwrecks give your units a 6+ Save-after-the-save and have a chance to deal damage to enemies, so they are fairly useful, though less so in a pure Akhelian army. Errata'd so that the shipwreck must be placed more than 6" away from objectives or any other shipwreck.

Command and Mount Traits[edit]

Command Traits[edit]

  1. Merciless Raider: Can reroll run and charge rolls. Interesting for Steed of Tides shenanigans.
  2. Hunter of Souls: Reroll 1s To Wound. Shame this doesn't work on a mount's attacks, but still nice.
  3. Unstoppable Fury: During High Tide, your General adds +2 to his attacks. Again, shame this doesn't work on mounts, but it still makes an Akhelian King terrifying.
  4. Born From Agony: Your general has 2 more Wounds. Always nice to shrug off an additional Arcane Bolt.
  5. Nightmare Legacy: Enemy units within 12" take -1 Bravery. Not a strong effect, but in a fairly large bubble, so it evens out.
  6. Lord of Storm and Sea: +2 Bravery for Idoneth Deep in units wholly within 12". Since your units aren't exactly blessed with great Bravery, this is pretty nice.

Mount Traits: Deepmare[edit]

With Broken Realms, we got Mount Traits for Deepmares. Yes, Volturnos' mount Uasall can take one. One Deepmare may take one trait, for every battalion one additional Deepmare may take a different trait, so no trait twice and nobody gets two traits.

  1. Swift-finned Impaler: If the roll on the Deepmare Horn ability is 6, you do D6 instead of D3 Mortal Wounds.
  2. Savage Ferocity: Both Deepmare attack profiles get 1 extra attack.
  3. Voidchill Darkness: We got a winner lads, as every enemy model within 3" get to subtract 1 from their hit rolls.

Mount Traits: Leviadon[edit]

Also from Broken Realms, one Leviadon may take one trait, for every battalion one additional Leviadon may take a different trait, so no trait twice and nobody gets two traits.

  1. Ancient: You ignore rend of -1, but not -2 or more. This makes the Leviadons shiny new shell even harder to crack.
  2. Denizen of the Darkest Depths: One extra free Mortal Wound for the impact damage. Specifically states that you still do this extra Mortal Wound if you failed the roll to trigger Crushing Charge.
  3. Reverberating Carapace. Increase the Void Drum's range from 12" to 15".


Akhelian Artefacts
Can be given to an Akhelian Hero (so far only the Akhelian King, because Volturnos can't get one):

  1. Sanguine Pearl: Gives a 5+ save after the save in melee
  2. Potion of Hateful Frenzy: Once per game active in the hero phase to get + 1 to hit and +1 to wound for a round. Then they take 1 mortal wound in the following hero phase. Your personal super sayajin mode. Combine with Unstoppable Fury to make your King utterly terrifying for one turn. And don't forget to draw your Falchion to make the most out of it.
  3. Ankusha Spur: +3" to movement and the mount rerolls 1s to hit To Wound after the Errata because someone realized that the King's aura already gives him the 1s To Hit thing regardless
  4. Armour of the Cythai: Enemy gets -1 to hit if they target the bearer in melee. You're probably better off with the pearl.
  5. Bioshock Shell: Once per battle at the start of the combat phase you can inflict D3 mortal wounds on each enemy unit within 3". You have so few ways of dealing Mortal Wounds that this is interesting. That said, is it really worth running this on a 230 point King?
  6. Abyssal Blade: You can improve the rend characteristic of 1 weapon carried by the bearer. Also increase the damage of that weapon by 1 if targetting SLAANESH. Too situational, but interesting.

Idoneth Artefacts
Can be given to any Idoneth Deepkin Hero:

  1. Rune of the Surging Tide: Use at the start of hero phase once per battle. It has 2 modes: adds 1" movement to all friendly deepkin or takes 1" from all enemies until your next hero phase. Neither a big buff nor a big debuff. Kinda like a mini Chronomatic Cogs.
  2. Black Pearl: It is the fastest ship with Johnny Depp usually as the captain. Oops, wrong universe. I mean it gives a 6+ save after the save.
  3. Lliandra's Last Lament: Once per battle you can have all friendly deepkin completely within 18" skip their battleshock test. Very interesting, especially when running a big unit of Allopexes.
  4. Terrornight Venom: Pick a weapon. You can reroll wound rolls of 1 for that weapon. Also gives a permanent -1 to bravery to things wounded by that weapon. Not many weapons worth using it on.
  5. Cloud of Midnight: Once per battle at the start of any phase the bearer cannot be targetted for attacks, spells or abilities for that phase. They also cannot use attacks, spells or abilities that phase either. Due to a new FAQ when you activate this artifact the bearer is not counted for the Forgotten Nightmare rule.
  6. Whorlshell: Once per battle at the start of your hero phase you can pick an enemy HERO within 9" and roll 2d6. If you beat their bravery they get -1 to all hit rolls for the rest of the game. Since most Heroes you'd want to do that to have high Bravery... just take Brain Barnacles instead.

Isharann Artefacts
Can be given to any Isharann Hero:

  1. Steelshell Pearl: Gives a 5+ save after the save against missile weapons. Interesting if you want a cheap sacrifice to soak up fire thanks to Forgotten Nightmares, but other than that, it's useless precisely because of Forgotten Nightmares.
  2. Mind Flare: Once per battle at the start of combat pick an enemy unit within 3". They get -1 to hit for that phase. Meh.
  3. Dritchleech: All Wizards except Idoneth Deepkin get -1 to casts while within 18". Interesting, but remember that this will affect allied Wizards as well.
  4. Auric Lantern: At the start of your shooting phase pick an enemy within 18" in cover. They dont get cover until your next shooting phase. Not too great, since your shooting isn't exactly stellar. Except the debuff is not limited to ranged attacks; it is just applied in the shooting phase!
  5. Disharmony Stones: Once per battle at the start of your hero phase you pick up to 2 enemy heroes within 12" and then the opposing player must make a choice. 1) they roll a dice for each hero picked on a 3+ they take a mortal wound. 2) They roll a dice for each hero picked and on a 5+ they take d3 mortal wounds. 3) Each hero picked takes d3 mortal wounds. Then roll a dice, on a 4+ the bearer of this artifact takes d3. Be very careful with these, as they might end up doing nothing or doing something and hurting you as well. Also worthless against armies without many Heroes.
  6. Brain Barnacles: Once per battle at the start of your hero phase pick an enemy hero within 12" and roll 2d6. If the roll is equal or greater than the distance between them then that Hero gets -1 to hit and spell cast for the rest of the game.

Arcane Artefacts
Can be given to any Idoneth Deepkin Hero who's also a Wizard, so Tidecaster and Aspect of the Sea only:

  1. Arcane Pearl: Gives a 5+ save after the save against mortal wounds. Combines nicely with both the Aspect of the Sea's inherent toughness and the Tidecaster's Spirit Guardians. If you dont need another realm, pick Aqshy and get the 4+ mortal wound save item from there (Malign Sorcery Realm Artefacts are no longer valid in competitive play though).
  2. Sands of Infinity: Once per battle you can make a spell last for 2 rounds instead of one. You must use this before the cast and unbind roll. Very nice.
  3. Coral Ring: Gives 1 reroll for casting and 1 reroll for unbinding for the game. More reliability is never a bad thing.
  4. Bauble of Buoyancy: Gives fly and doubles their run roll. Just in case you want a Tidecaster to keep up with an Akhelian army. Consider picking up the Thermalrider Cloak from Aqshy instead (again, Malign Sorcery Realm Artefacts no longer valid).
  5. Kraken Tooth: Once per battle in your shooting phase pick an enemy unit within 12" and visible. Roll a dice and: 1: bearer suffers d3 mortal wounds, 2-5: enemy suffers D3 mortal wounds, 6: Pick 1 enemy model in the unit. If the wound characteristic is less than 10 they are slain. If it is 10+ they take 2d6 mortal wounds. The kraken does not mess around.
  6. Augury Shells: Once per battle at the start of the hero phase you can roll 2d6. You can choose to use that result for your casting roll or your enemies unbinding roll on spells cast by the bearer during that phase. You must choose to substitute the roll before rolling for the spell/unbind. Very nice. A terrible roll you can give to the opponent and a good one you keep to yourself. Again, more reliability.

Lore of the Deep[edit]

  1. Steed of Tides: Casting Value 5. Pick a friendly hero that is not a monster within 6". Remove them from the table and set them up within 24" of their original spot and outside of 9" of enemies. This counts as their movement in the movement phase. The Hero does not need to be an Idoneth Deepkin.
  2. Abyssal Darkness: Casting Value 5. Friendly deepkin are treated as being within cover while wholly within 9" of the caster until your next hero phase. Entirely worthless on your first turn and worthless on any other turn if you have a Leviadon This is no longer true. In fact, imagine Ishlaen Guard with a Leviadon plus this spell. Damn near impregnable.
  3. Vorpal Maelstrom: Casting Value 6. Pick a spot within 18" of the caster that they can see. Roll for each enemy unit within 3" of that spot, if the dice is less than or equal to the number of models in that unit they take d3 mortal wounds.
  4. Pressure of the Deeps: Casting Value 7. Pick an enemy they can see within 12" and roll a dice. If you beat their wound stat they are slain. Interestingly you pick a model with this, not a unit. So just point at that icon bearer in the Pink Horror unit to seriously piss your opponent off.
  5. Tide of Fear: Casting Value 6. Pick an enemy the caster can see within 12". Until your next hero phase that unit gets -1 to hit and to bravery. Nice, but remember that your Aspect of the Sea can do that to D6 units. Better yet, combine the two to make sure one enemy unit in particular is utterly screwed.
  6. Arcane Corrosion: Casting Value 6. This auto targets the closest enemy. Measure the distance between the caster and that unit. If the distance is: 12" or less: 1 mortal wound. 13-24": 2 mortal wounds. 25-36": 3 mortal wounds. 37-48" 4 mortal wounds. Such a weird spell. Interesting in that it is a damage spell that can be used turn 1, as most damage spells have too short a range for that to work, but Arcane Corrosion can't just be used turn 1, it's practically guaranteed to do quite a bit of damage then.

Isharann Rituals[edit]

Deepkin can cast 1 ritual a turn. At the start of your hero phase you declare which ritual you wish to cast, pick an ISHARANN HERO that is more than 9" away from an enemy and roll 2d6. On a 10+ the ritual succeeds and if not then nothing happens. You get +1 if the caster is within 1" of a Gloomtide Shipwreck, +1 if the caster is a PRIEST (i.e. a Soulscryer), +1 for each non priest Isharann heroes within 3", and +2 for each priest Ishaaran hero within 3". This is not a spell and cannot be unbound. They have no range, they simply affect the game. Be aware that mathematical your have to fish for at least a +3 for a better then 50/50 chance. So if your planning on needing a ritual to go off try and get at least two priests and keep them close to keep a floating +3 to cast them that can be further increased by more heroes or a Shipwreck if you desire.

The 3 Rituals are:

  1. Ritual of Erosion: Until your next hero phase your enemy does not get a cover bonus. Your go-to if you don't have an Eidolon around. No cover does horrible things to bulwark armies like Eternal Guard-Wanderers and Freeguild.
  2. Ritual of Rousing: Heal 1 Wound on each EIDOLON and they can reroll all failed hit and casting rolls until your next hero phase. In case you didn't realize, this is horrifying on an Aspect of the Sea with his two spells per turn.
  3. Ritual of Tempest: Until your next hero phase enemy models cannot fly. Unless the table is littered with terrain, this really only helps against Kharadron,gloomspite (squigs) and Nighthaunts, but it can be very good against. Although, shutting down your opponents ability to fly over your units means that they are going to have to fight through the rest of your army.


Named Characters[edit]

  • Volturnos, High King of the Deep: [270 pts.] An Akhelian King +1. For a measly 40 points more, Volturnos gets another swing with his weapons and far better buffs, such as the reroll-aura being extended to 18" and all Deepkin within that bubble also getting +1 to Bravery. But the real kicker is his shield: Whenever he's affected by any spell, you can choose to roll a D6 and on a 3+ that spell doesn't affect him (but works normally on everything else). Not only does that keep him relatively safe from enemy debuffs and damage spells, it also means you can drop Vorpal Maelstrom on top of him when he's surrounded by enemies. After Broken Realms: Morathi, he now gets potential access to a Deepmare Mount Trait, finally balancing out some of the downsides to having to take a named character as your general for his superior High Tide Command Ability.
  • Lotann, Warden of the Soulledgers: [70 pts.] Aka Octobro. With a fairly standard Hero statline but slightly above-average damage output thanks to the Ochtar, he's not too shabby on his own. Especially his 5+ Save-after-the-save is appreciated since he can't take Artefacts. But what you really take him for is his buff, giving Deepkin in general +1 Bravery and Namarti in particular the ability to reroll 1s To Hit in a massive completely within 12" bubble. Note that his bubble doesn't specify melee, so feel free to use it to boost those Reavers' shots. That said, if you play mostly Akhelians, then the Akhelian King does the buffing better.


  • Akhelian King: [230 pts.] As mentioned above, the generic Akhelian King pales in comparison to Volturnos, but that doesn't mean he's bad. He's worse at everything, but can take Traits and Artefacts, which can combine to make him either tougher or killier or supportier than Volturnos, though never all three (there is also nothing stopping you from taking one alongside Volturnos if you really want to). Whatever you pick, the Akhelian King is always a fast, reasonably tough and extremely killy Hero who provides good support to your Akhelians. His main weapon is either a Greatsword or a Bladed Polearm; the latter is better provided you can keep charging (perfect time to take advantage of Ebb Tide): 2", -2 Rend, and trades one attack for dishing out 3 damage instead D3 when he charges. If you can't reliably charge each time, the Sword and Spear actually mathhammer out to very similar damage (we are talking fractions here). One other thing he has over Volty is that you can stow the Shield and Draw the Falchion. This lowers his Save to a 4+, but gives you 3, 3+/4+/-/1 Attacks when when you really want to make sure something is dead.
    • (Note: Realm Artefacts from Malign Sorcery are now invalid)... Make Volturnos jealous of your prowess by giving your Akhelian King the Incandescent Rageblade from Aqshy. Having 1 of the bearers melee weapons scores 2 hits instead of 1 PLUS an extra attack profile that can be buffed by either the King's own Command Ability and/or the Unstoppable Fury command trait (in High Tide only) will please you.
  • Isharann Tidecaster: [100 pts.] A fairly survivable support caster with access to a number of very interesting spells. All in all, you only pick the lass for two reasons: One, you want a Wizard but don't have enough points for an Aspect of the Sea. Two, you take her as your general, because she can reverse Tides of Death. Combined with the Fuethán turning Ebb Tide into Flow Tide, this will give you a very fast, very aggressive army.
    • Another use, that pairs well if your going to have her sit out of combat and only included because of her ability to flip the tide, is to give the Arcane Corrosion spell, and use her as a little impromptu artillery piece. Putting her in the back corner and spamming the spell makes her an effective choice for throwing some MW downrange.
  • Isharann Soulscryer: [130 pts.] Count von Count here is a support character through and through. Fragile, with only milquetoast attacks, but blessed with a combo of bonus effects in that he can outflank along with 2 other Deepkin units (3 if you choose the Briomdar enclave) and on top of that the ability to add 3 to Deepkin charge rolls so long as they charge the one unit he points at. Also allows for some targetting shenanigans with Forgotten Nightmares, as you can force your opponent's backfield fire support to shoot your nigh-invulnerable Ishlaen Guard. Be aware that his special rule, seeker of souls, makes it so that Idoneth units within 12” have to charge the unit marked with this ability if they are going to charge anything this turn. You cannot opt out of this bonus, as every unit within 12 of the target must add 3 inches to their charge.
  • Isharann Soulrender: [80 pts.] The Soulrender wants to be a hybrid Hero killer/buffer. The latter role he pulls off remarkably well, reviving D3 plus however many models his Hook killed that turn Namarti models at the end of your battleshock phase. The former role... eh. His two hook attacks are fairly decent, with a rule that makes it better against Heroes, but it will take some prior damage for him to take down any Hero with 2 damage 2 attacks, even with the fish pitching in.

Eidolon of Mathlann[edit]

  • Aspect of the Storm: [330 pts.] With Broken Realms the Eidolons were finally revamped and since GW doesn't like updating the warscrolls on their site, that one is now out of date. The Aspect of the Storm remains the melee fighter he already was and his tricks are essentially the same. With 12 Wounds and a 3+ save he is happy to get stuck in there and with his two weapons in hand he is sure to bring the hurt. On the charge he is allowed to heal D3 Wounds, gains a fifth attack and one extra damage on his Spear and for the kicks he gets to retreat and charge again. His Stormshoal fish keep their attack, but now also provide him with a 5+ shrug. Pulling an enemy hero into the deeps no longer makes that hero worse at hitting and instead allows the Eidolon to hit on 2s with his own weapons and the Stormshoal on 3's. Why make the return of the enemy worse, if you can finally kill him outright? Lastly, his Drenched with Hate ability allows to add 1 to all wound rolls for friendly Idoneth wholly within 18". At 330 points, this Eidolon is finally playable, blends lesser units and Heros with 8 or less wounds will fold before his awesome power.
  • Aspect of the Sea: [330 pts.] You guessed it, this warscroll is now also out of date. Like his more murderous brother he got blessed with a 5+ shrug. He retains his vital +3 Bravery bubble, now as wholly within 18". Still very important to keep those Namarti where they are ought to be. The new Dormant Energies rule finally allows rerolls for all his magic rolls instead of only one, and if you don't use any of these rerolls in your hero phase, he gets D3 wounds back. Nice. His Weapons remain untouched, so while he wont kill as hard as the Aspect of the Storm, he still makes a good account of himself. As a Wizard, he casts and unbinds twice and boasts two spells. One either puts D3 Mortal Wounds on an enemy heals a Idoneth unit for D3 wounds, not bringing anyone back from the dead though. The other punishes D6 enemy units with a -1 to hit and Bravery until your next hero phase. He too dropped down to 330 points. Yes, this does indeed mean that since he was released he dropped by 110 points, a full quarter of his original cost. He too is finally playable, his biggest weakness being the short range of his spells.


  • Namarti Thralls: (Battleline, NAMARTI, 120, Min:10). Namarti Thralls are the quintessential aelven infantry: Extremely fragile and insanely killy. Seriously. Wildwood Rangers wish they were this scary. They attack with the standard elite infantry profile of 2 attacks 3+/3+/-1/1, but with the bonus of adding another attack against 1 Wound models and adding 1 to the damage against models with 4 or more Wounds. However, they also run around with 1 Wound, a 5+ Save and a paltry Bravery of 6. They also have Icon Bearers who gain one more attack and lets them reroll battleshock. Updated FAQ states that you can have 1 Icon bearer per every 10 models. The only thing that holds them back is that their weapons only have 1" of range, so you need to be careful with how to place them.
  • Namarti Reavers: (Battleline with an Isharann Hero as general, NAMARTI, 115, Min:10). Namarti Reavers are fast (8" and rerolls run) and equipped with really weird bows. At 18", they get one shot at 4+/4+/-/1, which isn't exactly stellar. At 9", they instead get three shots at the same profile. Still not incredible, but that sure is a lot of shots. And if they get into melee? Each of them has a Sword-Liberator's worth of attack. So these are Archers that are only effective at extremely short ranges. Think of them as less versatile but more killy Shadow Warriors and you're not far off.
  • Akhelian Ishlaen Guard: (Battleline with an Akhelian Hero as general, AKHELIAN, 155, Min:3) . Defendy cavalry. Huh. Ishlaen Guard is fast and has decent damage output, but their true strength lies in their shields. They ignore Rend and gain +1 to their saves when they charge, which they will since they move 14" and reroll charges thanks to their musician. So the opponent has to throw Mortal Wounds at them just to reliably get past their saves and even then each of the buggers has 4 Wounds.
  • Akhelian Morrsarr Guard: (Battleline with an Akhelian Hero as general, AKHELIAN, 195, Min:3) Same basic profile as the Ishlaen, but with 1 less attack on the weapons and no ability to ignore Rend. This seems lacking, especially considering they cost thirty points more. But then you notice that their spears gain Damage 2 and -2 Rend on the charge and that they can, once per game, drop 0.83 Mortal Wounds per rider on whatever pisses you off and you realize that they are wall breakers instead of walls. That said, just because they're missing the defensive abilities of the Ishlaen, that doesn't mean they're frail, as they still rock 4 Wounds with a 4+ Save. Got jacked up to 170 points in GHB 2019, not enough to make a massive difference.
  • Akhelian Allopex: (AKHELIAN, 110, Min:1, Max:3, Website Warscroll no longer up to date.) DUUNNN DUNNN… DUUUUNNNN DUUN… DUNDUNDUNDUNDUNDUN... Chariots in all but name. 14" flying, 8 wounds, 4+ save and no longer a Monster, so let's get to cover. Each has two riders, one who swings a sword and one of which mans the gun. One option is the Razorshell Harpoon, blasting away four shots 3+/3+/-1/1 Damage. The other is the Retarius Net Launcher, who slings out 1 shot 3+/3+/-/1. While that damage is worse than the Harpoon, you only need to hit your target for the prize - your fancy new rule "Entangled" triggers and the hit unit cannot pile in this turn. This means you get to take a nice old bite out of their flank with basically no return. Nice. The ranged options can be mixed within one unit now. In Melee the Crew stabs and prods the enemywith 6 attacks, hitting and wounding on 3s bcause you are aelves, but no rend. The shark itself doesn't have fins anymore and the bite changed a lot. It is now 3 attacks, 3+/3+/-2/2 Damage. If any enemy unit within 3" has suffered wounds or lost models this turn you get an extra bite, so let the crew swing first if you failed your shooting. Very nice with a Soulscryer. Finally, they can be taken in units of up to 3, which is very risky due to Bravery 6, but with a potentially huge payoff. In exchange, units of them make for an incredible target for the Akhelian King's Command. It'd be wasted on a single Allopex but on a unit of three? Oh dear. Just make sure you use Inspiring Presence on them until High Tide rolls around. Now at 110 points, so you can consider this living cruise missile.


  • Akhelian Leviadon: [340 pts.] Sea turtles, mate! Blessed be Morathi's treacherous ways, because finally the Leviadon has a warscroll that wasn't left in some half-baked beta state! The warscroll on the Website is currently not up to date. A fixed 10" flying move, a massive 16 wounds and a initial save of 2+ make this a tough shell to break. "Initial save?" you ask? Why yes, for as long as he only suffers 8 wounds this turtle now has a 2+ save, after which it starts to degrade increasingly fast to a 3+, when he has suffered 12 wounds it's a 4+ and on it's last fin it's save is a sad 5+, but at this point he is dead anyway. The weapons that this beast can bring to bear however will make damn sure that whoever breaks it's carapace will pay dearly for it. Its Razorshell Harpoon Launchers buffed to 8 Attacks 3+/3+/-1/1, delivering Dakka from 24". Its crew rather inconsequentially poke six times with no rend, and the real hurt comes from the turtle itself. Its fins cleave four times with 2" 2+/3+/-1/ starting at four damage a swing, that's sixteen wounds you can punch in somewhere. Its bite decided that it's old swingy ways are for losers, so it got two attacks, hitting on 2s, degrading as the Monster takes damage, wounds on a fixed 2+, -2 rend and three damage. No more sadness with a D6 roll for the damage done. In addition if you roll an unmodified hit roll of 6, you do 3 Mortal wounds now, or 6 if the target is a fellow Monster. And the Attack sequence actually ends now! Amazing! After you make a charge move you already do damage. Like the Deepmare of your Kings, you roll a D6, on a 2+ the charged unit suffers D3 Mortal Wounds or D6 if the unit's models only have 1 wound. This butchers small models, so Clanrats beware. We are not done yet. The old useless cover of the Void Drum is gone, now instead IDK units with 8 wounds or less and wholly within 12" just get +1 to their save. This is better than cover and stacks with it. If your Ishlaen Guard are here Turn 1, they have a 2+ unrendable save. Close by Namarti benefit even more, gaining +1 to hit in the Void Drums bubble, which is clearly intended to make them more of a viable choice. 340 points, Monster and a Behemoth.


Due to how Battalions are now universal, expect see the whole lot of this on the trash bin outside of narrative games. Bonus rules, traits and doodads are going to be likely added to the faction rules as default.

From Battletome Idoneth Deepkin[edit]

  • Royal Council: (610pt. min.) [Battalion: 140pt.]

Requires an Akhelian King (Or Volturnos), a Tidecaster, and a Soulscryer.

Adds a new Command Ability, if the Akhelian King is the general. You can add 3" move until next hero phase for 3 friendly Idoneth Deepkin within 12" of the Akhelian King. The Soulscryer and the Tidecaster have to be within 3" of the Akhelian King to use this. Effectively nerfs the Soulscryer's ability to outflank because he needs to be within 3" of the King to use the Ability of this Battalion (unless you take an extra Soulscryer via the Ionrach enclave). Either way, taking the King as general means you can't reverse the tides with the Tidecaster.

  • Akhelian Corps: (830pt. min.) [Battalion: 100pt.]

Requires a Akhelian Leviadon, 2-4 units of Akhelian guards and 1-2 units of Akhelian Allopexes

You can reroll a hit, a wound, a save, a run or a charge roll for one unit of this battalion wholly within 12" of the big turtle per phase.

  • Namarti Corps: (660pt. min.) [Battalion: 100pt.]

Requires a Isharann Soulrender, 2-6 units of Namarti Thralls and 2-4 units of Namarti Reavers

The Soulrender resurrects 3 models instead of D3 with his Lurelight ability.

  • Alliance of Wood and Sea: (1410pt. min.) [Battalion: 140pt.]

Requires (deep breath....) a Isharann Tidecaster, 2 units of Akhelian guards, a unit of Akhelian Allopexes, a unit of Namarti Thralls, a unit of Namarti Reavers, and some Sylvaneth - a branchwych, 2 units of Dryads and a Treelord Ancient

The Sylvaneth in the Battalion benefit from Emissary of the Deep Places regardless of your chosen Enclave.

Essentially a full Start collecting box of Sylvaneth, plus 4 more dyads. Also smart to buy one Awakened Wyldwood since the Treelord Ancient's ability Silent Communion gives you one per battle despite your Sylvaneth otherwise not having access to tree generation. Ideal for an existing Sylvaneth players wanting to branch out to something new (pun intended). But does it work as an useful army?

Other useful considerations would be that the two Sylvaneth Wizards in the Battalion don't have access to non-Warscroll spells, and especially considering that the one spell on the Treelord Ancient's scroll depends on Awakened Wildwoods to be useful, it's probably wise to take at least one Sylvaneth Endless Spell (or generic one for that matter) to give them something to do. Furthermore, Dryads are one of those units that doesn't perform well at their MSU size of 10 (getting a +1 to Save for 10+ models), so you should go ahead and plan on at least two units of 20 models (if not 30). Additionally, the added artefact you'll be getting from this Battalion will be wasted if you don't take at least one additional Idoneth Hero (since these Sylvaneth still count as Allies for the purposes of doling out artefacts). Finally, since the Allied Dryads don't actually count as Battleline (despite what Azyr says), you'll either need another unit of Namarti (if you take the Tidecaster as your general), or one of the Akhelian Kings (to make the Eels Battleline). Essentially, the Battalion is more for flavor, as it's super limiting of what you can actually end of taking in a 2000 pt army, but it could still be fun (especially if they update the Sylvaneth scrolls).

You could add two units of Kurnoth Hunters as allies (given anyone playing this will most likely have some lying around), but they wouldn't get the Tides Of Death (unless you went Ionrach).

From Battleforce Boxes[edit]

  • Deepsurge Raiding Party (660pt. min.) (not legal in matched play)

Requires an Isharann Tidecaster, 1 unit of Akhelian Allopexes, 1 Unit of Akhelian Morrsarr Guard or 1 unit of Akhelian Ishlaen Guard, 1 unit of Namarti Thralls, 1 unit of Namarti Reavers

This gives the Tidecaster the ability to negate the first wound allocation to a model from the battalion instead of itself.

From Broken Realms: Morathi[edit]

  • The Bloodsurf Hunt (570pt. min.)

Requires an Akhelian King, 1-2 units of Akhelian Allopexes, and locks you into the Ionrach Enclave

Kind of an interesting battalion choice, if you've ever looked at your sharks and wanted them to be meat shields for your glorious King. The Akhelian King model becomes a named character, Nemmetar, and gains the Lord of Storm and Sea command trait. Nice. BUT ALSO add 1 to hit rolls for your sharks' Barbed Hooks and Blades while wholly within 12" of Nemmetar. In addition, on a 2+ you can swap wounds from Nemmetar to Allopex units from the same battalion while they're within 3" of him. It may seem counter-intuitive to have your super killy sharks taking wounds for your Akhelian King, but if you're using Nemmetar as an anvil and Allopexes as a hammer with maybe a Leviadon backing them both up for +1 to saving throws...well, suffice it to say that you will have Nagash himself weeping that you got a First Cohort battalion that can actually be used.


From Battletome Idoneth Deepkin[edit]

  • Phalanx: (3710pt. min.) (30810pt. max.)!!! [Battalion: 120pt.]

1 Royal Council, 2-4 Akhelian Corps, 2-4 Namarti Corps

The big one. Once per battle you get an additional High Tide.

The Enclaves[edit]

They are akin to the Daughters of Khaine Temples. Each has unique special rules for your army and allows you to upgrade one of your Warscroll Battalions

  • Ionrach: The enclave of magic and allies. +1 to cast and unbind rolls for your Wizards, which, as you know, is invaluable. However, your Command Trait is locked into the Ionrach-exclusive Emissary of the Deep Places, which provides your allies access to the Tides of Death rules. Great if you have allies (or mercenaries), worthless if you don't. On the flip side, seeing as Volturnos' main drawback as a named general is that he can't take a command trait, if you're already not bringing allies, this is the perfect time to bring him along and minimize that drawback. Doesn't really fit the lore so well, but it is what it is... Also your Royal Council can have up to 2 Soulscryers and Tidecasters. Also note that with Ionrach, your allies DO NOT gain the benefit of forgotten nightmares (they still screen your Idoneth units however).
  • Dhom-Hain: The enclave of more elite, monster-killing soldiers. Akhelians and Namarti reroll 1s To Hit on the charge. Relatively meaningless as Lotann and the Akhelian King respectively do the same whether you charged or not, but nice if you find yourself outside the relevant bubbles. Lotann and the Akhelian King only do it for units that are WHOLLY within 12 inches of them, and this rule applies to anything not an Isharann or an Eidolon. So if you want to keep your entire, very mobile, army inside a 12 inch bubble, this rule is meaningless, otherwise it's very good. Your Akhelians also reroll Wound rolls against Monsters (not just in melee, so feel free to reroll those wounds on your Allopex and Leviadon's shooting attacks when firing at a monster). Interesting against some armies, worthless against others. Also your Akhelian Corps can have up to 6 units of Akhelian Guard. Dhom-hain is notable as one of the Enclaves that have no restrictions whatsoever.
  • Fuethán: The most aggressive enclave (including the mounts). You reroll 1s To Wound with your mounts. Also, during Flood Tide all your units reroll 1s To Hit and Ebb Tide turns into another Flood Tide. You'll really miss that fall back + charge on turn 4, but in exchange, a Tidecaster can make you super fast by giving you Flood Tide on turn 1 and High Tide on turn 2. The Tidecaster has to be the general for that, which locks you out of Akhelians being battleline and lets you not use the command abilities of the Akhelian Kings. Also, your Phalanx can contain up to 6 Akhelian Corps. Not that you will ever use a Phalanx.
  • Mor'Phann: The death enclave. Your Soulrenders raise an additional 3 models. This is huge and out-Death's Death armies. However, your Tidecasters can't take Lore spells and instead get Freezing Mists, which drastically lowers an enemy unit's Pile In move. Also, your Namarti Corps can have 6 units of Reavers (errata'ed due to redundancy with 2-6 Thralls already being the base amount for the Battalion).
  • Nautilar: The most defensive enclave. Your units reroll all failed Hit rolls if they were charged that turn. Not that your opponent needed more discouragement from charging your Namarti. Their Tidecasters lose access to lore spells and instead get Protective Barrier, which targets a friendly unit and lower the Rend of any enemy attacking them. Also your Akhelian Corps can have up to 2 Leviadons.
  • Briomdar: The enclave with the most mobility. Your Soulscryers can take up to 3 units along and place them 18" away instead of 12. Also, your units can move over terrain (but not enemy units) as if they were flying. Not too great since most of your army already flies. Also your Namarti Corps can take up to 6 units of Reavers. Again, it is notable that the Briomdar have no restrictions to their name.


Note that with an Ionarch army all allies benefit from the Tides of Death rule, which benefits many allied units in various ways.

  • Cities of Sigmar: They offer the widest variety out of all the allies, particularly the aelven forces. Here's a more comprehensive description of what works with Idoneth:
    • Word of Pain from a Sorceress helps with -1 to Hit spam in a mage heavy list. (Just remember that they're susceptible to being sniped out).
    • Order Serpentis provide expendable cavalry with good saves to soak up fire for your Akhelians. A Black Dragon or War Hydra with Ionrach are good choices for fast heavy hitters and/or shooting.
    • While Scourge Privateers would be great thematically, only the Scourgerunner Chariot is really worth considering from this group (and there's a lot of bad blood between the two factions lorewise).
    • Shadow Warriors can deepstrike, and (if in cover) outshoot Reavers from afar (though they're less mobile once on the field).
    • Wanderers also offer several benefits (though most of the following description is outdated). A unit of 20 Glade Guard in your army provides you with a highly reliable "remove lynchpin" button that will likely enrage your opponents. Sisters of the Thorn are an awesome addition to a Cavalry army and provide a very nice spell to boot. Eternal Guards re-roll saves of 1 and 2 if they are in cover, are as fast as Namarti Thralls and cost 70 points (currently 130) per 10 models (with a super discount at max size). A Waywatcher has the invisible hunter rule, which gives shooting units that target him -1 to hit, and can be given to other Wanderer units within 18" for 1 command point (combine with Tides of Death to make shooty armies cry).
    • Battlemages are excellent support units that can be tailored to your needs, and the Battlemage on Griffon packs a punch too.
    • Phoenix Temple are amazing. Phoenix guard can eat enemy fire with minimal losses given their 4+ save and a 4+ save-after-the-save. Throw in a Phoenix Guard Anointed and they not only become fearless but the Anointed gives you an extra dispel. The Flamespyre Phoenix is also a great unit, trading the dispel for dropping MW on enemies and a one-use chance to come back from death on a 4+.
    • Ironweld Arsenal Gyrobombers are a good and cheap choice for dropping MW on enemy units with their bombs, but Gyrocopters with Steam Guns are both much faster (better able to keep up with IDK flying units) and have a MUCH more potent close-range, anti-horde missile attack.
  • Daughters of Khaine: The best option by a long shot. What they bring are cheap and expendable units of 90 points per 5 Harpies that can Deep Strike in, and help block shots for the rest of your army via Forgotten Nightmares. 2 Units of Javelin Harpies, or one unit of Sword Harpies is pretty likely to one shot a 5 wound hero to boot. Doomfire Warlocks are also solid allies for a Cavalry army and easily able to keep up as well as providing good shooting and a source of mortal Wounds. Your best bet here is probably a unit of Khinerai, seeing as how they can deepstrike independently from any other unit, and offer a decently strong enough attack to help shift an chaff unit off a back field objective. It doesn't hurt that they are cheap points wise too. The new Khanite shadowstalkers are quite good as allies, being able to teleport wherever they want. For a hundred points they are an interesting 9 man objective grabber, because sometimes your eels can't quite do it alone.
    • Alternate Opinion: While Daughters of Khaine are indeed an extremely powerful force on their own, they don't make very good allies for a number of reasons. They excel at being an extremely aggressive force when you pile on their faction bonuses (escalating table, 6+FNP, Temple abilities, extra prayers, their NUTS spell lore, not to mention any number of internally consistent abilities and rules) on their own without those they tend towards being overpriced or fragile. While you might get some mileage out of a unit of Khinerai or Doomfire Warlocks, you'd probably be better off with some more Idoneth.
  • Stormcast Eternals: For a Namarti-heavy army, Liberators or Sequitors make fantastic cannon fodder when combined with a Lord-Castellant and Forgotten Nightmares. Other than that, Vanguard-Raptors make for some nice budget shooting. Fulminators are a nasty addition to any Cavalry heavy army, and combined with Tides of Death, will get your opponent to flip the table fast. A Knight Azyros can give your units a reroll 1 to Hit for enemies in 10". Also, a Knight Vexillor might use his redeploy ability to make your Stormcasts keep up with your Idoneths. A Celestant-Prime waiting in the heavens to boost his Attacks characteristic and then dropping in on turn 3 in High Tide (if Ionrach) can do all kinds of work. Turn 2's not bad either so that you can take advantage of another Cometstrike.
  • Sylvaneth: The only things worth considering here are Kurnoth Hunters for some additional shooting and Tree Revenants for Warmachine hunting without investing hundreds of points into a Soulscryer and an escort. Additionally, you might want to consider their Outcasts Battalion (3 units of Spite-Revenants), which at 280pt for the minimum-sized battalion, will likely remain the cheapest way to squeeze an extra battalion in. That said, it's currently impossible to field this in a Deepkin list in Vanguard and meet all of the faction-units-per-allies-units requirements, so save this for your Battlehost-and-larger games.
  • Gotrek: Despite costing 520pts, Gotrek can be brought as an ally in any Order faction even if that's more than the usual allies allowance. It's worth mentioning for the Ionrach enclave because he'll get the benefit of the Tides. Gotrek's an absolute beast in melee but is let down by his low movement and the fact he can never be teleported/ambushed onto the board etc; however, he would love to be able to run and charge, and retreat and charge, and Ionrach lets him do that.
  • Bundo Whalebiter: A Kraken-eater Mega-Gargant mercenary available to all Order factions. Taking him uses up your entire ally points allowance and he ignores any Behemoth or Hero limitations. A big terrifying centerpiece who can kick objectives around and instantly kill models by shoving them into his net. You can choose at the start of the Combat phase for him to fight at the end of the phase, in exchange for re-rolling failed hit rolls. If you want a big monster that isn’t the Turtle, then this is your pick.

Lethisian Defenders[edit]

From the Forbidden Power expansion, this odd army coalition of Idoneth, Stormcast, Kharadron, Fyreslayers, and a random Excelsior Warpriest (w/Gryph-Hound) offers you new Allegiance Ability synergies on a level somewhere between those of the regular faction-only perks and the super basic list for Grand Alliances. By choosing this allegiance, all of your units gain the keyword LETHISIAN DEFENDER and gain access to a couple unique Battle Traits, a Command Ability, 3 Command Traits, 3 Artefacts of Power, and 3 Prayers (arguably the focal point of the Allegiance). Unlike simply taking allies in an otherwise Idoneth list, which is limited by the 1:4 unit ratio rule and (in Pitched Battles) the ≤ 20% pts rule, this allegiance allows you to take basically whatever you want from the four armies (two of which you previously had no access to without pulling back to basic Grand Alliance: Order), with the following exceptions:

  • no Hammers of Sigmar (most Stormcast named heroes) [notable exception being the Celestant-Prime]
  • no Vostarg units (Fyreslayers) [but Kharadron named characters are legal]
  • not Volturnos [though you can take Lotann]
  • Battleline is restricted to the armies' vanilla offerings (Arkanaut Company, Liberators, Vulkite Berzerkers, and Thralls) since you can't take the other options without allegiance to the specific factions). One notable exception here that might (but hopefully won't) be errata'ed is that Kharadron Endrinmasters (w/Dirigible Suits) as your general can currently grant you access to Skywardens and Endrinriggers as Battleline w/o KO allegiance, allowing you the potential to make an all-flying army with balloon-boiz and your Akhelains/Eidolons (plus whatever scattered Stormcast units you like).

Otherwise, all other units from the four armies are legal, though of course it makes sense to lean in on priests since all priests in your army gain a free prayer that, like most prayers in the game, goes off on a 3+ and can't be unbound. Also, one of the Command Abilities makes your non-priest general a priest as well, or gives a priest-general access to another prayer. Currently, in addition to the Excelsior Warpriest (a fantastically efficient option with a solid prayer of his own and able to unbind one spell per enemy hero phase), the four armies offer us access to the following priests:

  • Stormcast: Lord-Relictor, Lord-Veritant (the superior option by far, super anti-Wizard)
  • Fyreslayers: Auric Runemaster, Auric Runesmiter (able to deepstrike 1 Fyreslayers unit), Auric Runesmither on Magamadroth
  • Idoneth: Isharann Soulscryer (notably lacking a prayer of his own)
  • Kharadron: unfortunately no priests (though an Aetheric Navigator really should be)

The Battle Traits for the Army are as follows:

  • all units can re-roll Battleshock tests (sadly mostly redundant for all Idoneth squads except Allopexes)
  • all Human and Duardin units get +1 to-Hit in melee against enemies that charged them (on that turn)
  • all Akhelian units get +1" Move and +1 on charge rolls, but sadly doesn't help non-Akhelians
  • Command Ability: only works for Liberators wholly within 12" of a Stormcast Hero (gives them +1 Save in exchange for not being able to pile-in) [meh]


  • you no longer benefit from any of the army's Allegiance-specific synergies (most-notably here, Tides of Death and Forgotten Nightmares), but you get to have fun allying with Duardin, more Stormcast, and have some Priestly fun!
  • there's no specific lore to the army (besides the prayers), but if you want Wizards, you can always take Endless Spells or use the one Realm Spell from GHB20 (same goes for one extra artefact)
  • unfortunately, there's no fix if you don't like the 3 Command Traits
  • no new Warscroll Battalions, but you're allowed to use any of the existing ones

Ultimately, though most-likely not powerful enough to be competitive, I hope that GW will make more coalition allegiances like this, as it not only mixes things up, but it creates opportunities for you to collect and learn other armies, and it's super fluffy lore-wise. Plus, the Grand Alliances really don't have enough going for them, so this kinda makes up for that, meeting halfway between.

Army Building[edit]

There aren't a ton of options for building diverse armies since the Idoneth model line consists of 8 Leaders, 5 units with only one unconditional battleline and a behemoth. However with the addition of Enclaves your army will perform a bit differently and allows for a small but not insignificant level of specialization.

What to start with?[edit]

  • As the name suggest, the Start Collecting! kit is a great way to start your collection, giving you 10 Thralls, 3 Eels and one Soulrender.
  • Battleforce box being released for Holidays 2018. $170 (USD) will net you a Tidecaster, 10 Namarti Thralls, 10 Namarti Reavers, 3 Eel guard riders of your choice, and 2 Allopexes. Not a bad variety to start with, and is over a hundred dollars in savings, if you can somehow get your hands on it.
  • Grab an Akhelian King kit and build either Volturnos or the stock King model. Both are fine, though Volturnos outperforms his nameless counterpart before taking Artefacts and Command Traits into consideration. Either model is a fine addition to your army. Better yet, pick up the Broken Realms: Morathi Battalion Box for the Bloodsurf Hunt, which includes not only the Akhelian King kit, but also two Allopexes, all useable in a new Battalion that's actually solid (especially if FAQ'd out of being subfaction-locked to Ionrach).
