Whenever the wearer is grappling (whether on the offense or defense), this shirt automatically bursts into flame, dealing 1d6+10 points of fire damage every round to anyone grappling the wearer. The flames do not harm the wearer and last one round (though it continues to burn if the wearer is still grappling after one round). The shirt burns for a maximum of 10 rounds per day. These rounds do not need to be consecutive.
