This cloak has 5 charges. Once per turn, you can spend up to 5 charges and 10ft of your movement per charge to make each creature within 5ft of you make a DC 15 Dexterity save and take 1d10 Fire damage per charge on a fail, or half as much on a save. Creature that take damage this way cannot make opportunity attacks against you until the end of your turn. Regains all charges at dawn.
