Horned Epidermis

Your skin is covered in jutting pieces of bone and horn-some of them small nubs, others razor sharp and easily capable of piercing the skin of foolish foes.

You gain the following benefits:

• While you are unarmed, you can use Constitution instead of Strength for the attack and damage rolls of your unarmed strikes.
• You increase the primary damage dice of devil’s strike to 3d10.
• You gain AC 12+Dexterity modifier (natural armor) while not wearing any armor.
