Hellfire wyrm

Description
Hellfire wyrms are draconic agents of the Nine Hells of Baator that live among humanoid races on the Material Plane. They are masterful power brokers, manipulating people and events in subtle ways. Hellfire wyrms can steer rulers to fight in unjust wars, or support unholy alliances, or even commit despotic acts against their people.

A hellfire wyrm is a diabolic-looking, winged dragon with vicious bone spikes jutting from its head and shoulders. Smoke rises continually from its scales, and its eyes burn an intense yellow. The monster’s scales shift in color to give the appearance of flowing molten lava, and they stink of brimstone.

Hellfire wyrms entrench themselves in regional politics by using their knowledge, wealth, and persuasive abilities to force through their foul agendas. The typical wyrm does not limit its actions to any one kingdom, and it often has a different identity for each realm it visits. It takes great pains to hide its draconic form, usually assuming the shape of a charismatic tiefling when dealing with humanoids and assassinating anyone who learns its true identity. Hellfire wyrms retreat to secret lairs when not actively scheming.

A hellfire wyrm speaks Draconic, Infernal, and Common, as well as the languages of any nearby humanoid races.

Combat
Utterly fearless and almost unstoppable in battle, hellfire wyrms are expert tacticians.They keep to the air, slinging mindaffecting spells and withering breath attacks at their enemies.
