Adamantine Body

Your bones have been reinforced with adamantine. Any critical hit against you becomes a normal hit. This also gives you resistance to all forms of non-magic damage, excluding acid and necrotic.    Once, as a reaction, you can gain resistance to bludgeoning, slashing or piercing damage against a single attack. You can't do it again until you complete a long rest.    Your armor bonus is increased to +8 and you gain damage reduction of 5 hp. However, your base land speed is reduced to 20 feet, and you are considered to be wearing heavy armor. You have a +1 maximum Dexterity bonus to AC, a -5 penalty on all skill checks that armor check penalties apply to.
