Imperial Gauss Flayers. No really.
Adrathic Weapons are a type of disintegration weapon used by our very special boys in gold.
These are relics dating back to the Dark Age of Technology and are believed to be unique to Terra. They use dangerously unstable but powerful energy beams to sever the internal bonds of matter, causing objects in their path to unravel. The only evidence that the victim existed is a flaring after-image of what was.
Such weapons were legend during the Age of Strife and were prized by the Techno-Barbarians of Terra. When the Emperor emerged he had all Adrathic Weapons given to him on pain of death. These weapons were then issued to his trusted Custodians and are used against the deadliest foes. The technology behind Adrathic weapons are even kept from the Mechanicum. More like no one knows it, even them, which is why they are found and claimed instead of created.
Unfortunately, they are all pretty short ranged despite their awesomeness, this is for the sake of keeping the game balanced we suppose.
Adrastus Bolt Caliver
See main page, Adrastus Bolt Caliver.
Used on Guardian Spears or twin-linked with Aquilon Terminators. These guns, especially the the twin-linked variety, notoriously look like toasters. Despite this unfortunate design, the Adrathic Destructor can atomize the strongest enemy armor into a mist of glowing vapor.
These guns unfortunately, aren't decked out in gold.
The Adrathic Destructor like all Adrathic weapons, are all AP2 with Instant Death, Armorbane, and Gets Hot. The Destructor itself is a 12" S5 AP2 Assault 1 weapon. It is by far the most 'common', available in some form or another on most infantry models.
Heavy Weapon mounted on Gyrfalcon Pattern Jetbikes. These are the larger variant of the Adrathic weapons and are too heavy and cumbersome for even the overpowered Aquilon Terminators.
These guns are designed to rip apart vehicles ranging from small skimmers to superheavy tanks. Seeing as how the average pilot for the Gyrfalcon is as tough as a Primarch, much pain is to be expected in the rectal region.
The Adrathic Devastator, like all Adrathic weapons, is AP2 with Instant Death, Armorbane, and Gets Hot. The Devastator itself is a 18" S6 AP2 Heavy 2 weapon and can do a number on heavy infantry and vehicles. They are an upgrade for the Jetbike and the Pallas Grav-Attack.
