Raking Claws (4e Feat)
From D&D Wiki
Raking Claws [Racial]
Quick swipes work fine for some, but you'd rather your opponent fall after one good slash.
Prerequisite: Claw Fighter, Level 11
Benefit: You can treat your claws as a single weapon with the versatile property. Increase the damage die by one for any attack you make in this fashion (from 1d4 to 1d6, for example).
