Vicious claws grow from your fingers. They are finesse unarmed attacks that deal 1d4 slashing damage and 1d6 extra damage of a type determined by the dragon in your bloodline (see the table in dragon breath). Your scales from blood magic glow with faint energy, giving you resistance 5 to the same damage type.

Heightened (5th) The extra damage increases to 2d6, and the resistance increases to 10.

Heightened (9th) The extra damage increases to 3d6, and the resistance increases to 15.
