A set of chain mail armor adorned with pieces of spines harvested from a Wyvern.  

While wearing this armor, when a creature attacks you with an Unarmed Strike or Natural Weapon and hits you, you can use your reaction to deal 1d4 piercing damage plus an additional 1d4 poison damage. 

Made of interlocking metal rings, chain mail includes a layer of quilted fabric worn underneath the mail to prevent chafing and to cushion the impact of blows. The suit includes gauntlets.
