Nether Demons are fiery minions of the Demon Chieftain and spawn in packs throughout Demon Castles in the Nether. They are added by the Nether Expansion idea pack. They are mottled red and carry a Netherrack Sword. Caution is advised when fighting them, as the sword's fire will never go out except in water, and there is none in the Nether. A Water Bottle can be drunk to stop burning. Nether Demons may also equip and wear Netherchain Armor.
Relations with Imps
When a Nether Demon spots an Imp, they will strike it once for and then ignore it, as if punishing it. Devils share this behavior.
