Armor (breastplate), very rare
A shield with the head of Medusa on it. As an action, a player can hold it up and the creature facing it must roll a DC 16 CON saving through, or be petrified until the next day or until a potion of healing(greater) is fed to them.
This armor consists of a fitted metal chest piece worn with supple leather. Although it leaves the legs and arms relatively unprotected, this armor provides good protection for the wearer's vital organs while leaving the wearer relatively unencumbered.
