Some demons which are made purely of fire, warm to the touch when calm, but dangerous to touch when aggravated, they have minor shapeshifting skill, which means more simple things such as making their arm a blade, transforming into a simple blob of fire to disguise themselves in a bonfire, ect, very limited.


These demons can eat minerals, and begin forming a metallic skin, and they turn their bodies into weapons, and can have their midsection explode at will, and they will go back to being regular fire demons, until they eat enough minerals to form a metal skin again.
