Pyromonstrum
Description: Pyromonstrum is a large, dragon-like Phantom with no wings. It has two horns of varying shape, size, and length, an arrowhead on the tip of its tail, and spikes going down its “spine”. It has the power to breathe fire.
Vitality: The flame sac, located in its throat
Behavior: When Pyromonstrum finds someone who fears it, it’ll thrash them without even the slightest hint of subtlety. Biting them, clawing them, stabbing them with its tail. When the victim is sufficiently beaten, it will torch them until their body is fully cremated.
What to do if you encounter it?: If there’s anything in the world that Pyromonstrum fears, it’s water. It seems to “burn” its skin. Most Pyromonstrum live as far from any body of water as possible, though.
