Crystal Skin

You have infused your skin with crystalline power, gaining the following benefits:

• Increase your Constitution by 1, to a maximum of 20
• When not wearing any armor slashing and piercing damage from nonmagical weapons is reduced by 2 but bludgeoning damage from nonmagical weapons is increased by 2. In addition whenever you take nonmagical bludgeoning damage from a melee attack, the attacker takes 2 points of piercing damage from the shards that shatter off your body.
