Cinder Rat

These oversized rodents are made of smoldering charcoal and elemental fire, and noxious fumes continually bellow from their flaming flesh. Even other fire elementals find cinder rats unpleasant and are glad when they're summoned away from the Plane of Fire.

Fire elementals are destructive manifestations of the scorching Plane of Fire. Although most fire elementals revel in the chance to experience new kinds of fires away from their home plane, even the most considerate fire elemental can be a danger to humanoids and their property.
