Morph Biter (3.5e Feat)
From D&D Wiki
Morph Biter [Special]
Bite. Bite hard.
Prerequisite: must be able to change shape in one of the following five ways: change shape supernatural ability, shapechanger subtype, polymorph as a spell-like ability, able to cast the polymorph spell, wild shape or similar class feature
Benefit: You gain a bite attack (which deals 1d6 + strength bonus of piercing, slashing, and bludgeoning damage). If you are in a different size, see table to increase or decrease damage. If you already have a bite attack, its damage increases as if the size modifier increased by one.
Special: This feat can be taken up to 3 times. The final damage for the bite attack is that of 2 size category larger than your size, even if you originally had bite attack before taking this feat. If you cast the polymorph spell, has polymorph as a spell-like ability usable less often than at will, or has the wild shape class feature, then this feat loses function when you cannot use them.
