Description
Large, bone spikes jut from it's head and shoulders while smoke is continually emitted by it's scales which seem to flow like molten lava across it's huge body. Their eyes burn bright yellow and they stink of brimstone. If they appear to humanoids though, they usually take the form of a tiefling.

Combat
Hellfire wyrms prefer to manipulate people and politics from behind the scenes, however if forced into a combat situation, they excel at tactical maneuvers, able to turn enemies into friends and blast the rest with its powerful breath weapon. They also have the ability to temporarily summon Baatezu allies and burn anything that gets close to them.
