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 armour, slashing and piercing damage you take from non-magical weapons is reduced by 2 but bludgeoning damage from non magical weapons is increased by 2. In addition whenever you take non-magical bludgeoning damage from a melee attack, the attacker takes 2 points of piercing damage from the shards that shatter off your body.
