Claws of the Beast (3.5e Maneuver)

SNIKT!

You summon claws from your hands, allowing you to use them as primary natural weapons that deal 1d6 + strength modifier in damage, with a 20/x2 critical. If you already possess claws, you deal damage as if you were one size larger. Your claws become enchanted based on your ranks in Control Shape.

This maneuver is a supernatural ability.
