Robe of the Fire Rat

Wondrous item, rare

This blazing crimson robe is woven from the hair and fur of creatures from the Elemental Plane of Fire. A robe of the fire rat is immune to fire damage and grants its wearer fire resistance. As a bonus action, the wearer can speak a command word to shroud the robe in fire for 1 round. Any creature that strikes the wearer with a melee attack while the robe is enshrouded in flames takes 1d6+10 points of fire damage. A successful DC 13 Dexterity saving throw negates the damage. A creature attacking with a reach weapon isn’t subjected to this fire weapon.

This ability can be used for up to 10 rounds each day.

These rounds don’t need to be consecutive.
