Favor the Fang and Claw (3.5e Feat)
From D&D Wiki
Favor the Fang and Claw [General]
You cannot help but favor the natural gifts of your beast heritage, something those of your mortal kin lack.
Prerequisite: You must have the Beast Heir template.
Benefit: The damage of all of your natural weapons increase by one step, as if your size had increased by one category.
