Steel nails

You transmute the keratin in your body to steel gaining these effects:

You gain a Claw attack that reaches up to 5 ft dealing 1d4+ your strength modifier, dealing slashing damage instead of bludgeoning damage normal for an unarmed strike.

If you already have a claw/talon attack increase the die from 1d4+ your strength modifier to a 1d8+ your strength modifier.
