Porcelain Skin

Your skin is forged from delicate porcelain, which shatters into shards when struck:

• Increase your Constitution score by 1, to a maximum of 20.
• When struck, shards of your skin shatter and spray out to an attacker.  As a reaction when struck, these shards may affect the enemy for damage equal to Dex Bonus + Con Bonus + Proficiency Bonus.  The enemy may make a Dex save (DC: 8 + Con Bonus) to halve this damage.
