At-will, std, melee; you destroy a target's soul utterly, taking its power into yourself (Cha negates). The target must be a captured soul, a helpless creature, or one at 0 HP. This is annihilation, not death: a devoured soul cannot be resurrected by any means short of a deity or a whole-soul Wish.

Devouring grants you the soul's full worth in shards, plus one of the following, your choice, permanently:

Devouring a soul is a mortal sin of the first order. The shards know where they came from.
