Efreeti

Efreet (singular: efreeti), or efreeta for females, are a type of genie native to the Elemental Plane of Fire. They are unpredictable creatures with fiery forms and spectacular magical powers.
Efreet are humanoid in appearance. They were very tall, generally reaching heights of 12 feet (3.7 meters), and massive and solid, weighing 2,000 pounds (910 kilograms). They are well-muscled and have red or black skin that are always burning. For this reason, many resembled devils and are often mistaken for them. Their bodies are supposedly composed of basalt, bronze, and solidified fire.
Efreeti magic is comparable to that of other powerful creatures, such as demons and liches, and are quite versatile. One area in which it is preeminent is in magical weaponsmithing. Efreet are particularly renowned for their ability to create flaming weapons.
