Armiger

From 1d4chan

Armiger is a Spheres of Might based third party class for Pathfinder. Armiger's main gimmick is that they can customize three (more at higher levels) weapons every day (or, with the right character option selected, after spending 10 minutes and once per day as a move action), adding temporary talents as long as the weapon is wielded. This makes them "prepared" casters practitioners to the normally spontaneous system. They also gain various other abilities that make them good at switch hitting.

The ability to swap talents could make this a Tier 1 Spheres of Might class, but in practice, the fact that the spheres best suited to saying "no" to a problem don't really make sense as being part of a custom weapon (How does changing up your sword teach you how to make a camera?) and the need to have access to a sphere to add a talent to a weapon bring it down from abusable. In practice it's tier 2 (if worked for), tier 3 (if competently played) or very low (due to high customization).
