race features:
Razorback: When you are struck by a creature within 5 feet of your, you can use your reaction to cause that creature to take 1d4 piercing damage from the barbs on your shell.
Razor Fist: Your barbed fists are natural weapons, which you can use to make unarmed strikes. If you hit with them, you deal piercing damage equal to 1d4 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.
