Learned From Barghest

Your mouth widens and you devour the corpse in a flash. Rather than filling you, this grants you a +1 profane bonus on attack rolls, CMB rolls, saving throws, and skill checks. You also gain 5 temporary hit points. Bonuses from up to five castings stack.

Note To learn this spell, you have to somehow observe your own corpse being eaten by a barghest.
