Fire Imp

Fire Imps are a Caster enemy found only in the The Underworld. They shoot three volleys of Burning Spheres which go through tiles, but can be halted by the swing of a weapon. Fire Imps will try to teleport to you if you run away from them far enough that they're offscreen, after they get hit, or after they shoot three Burning Spheres. They can also drown when caught underwater but will most likely teleport away before suffocating.

Fire Imps will, however, follow you if you try to flee (unless you teleport away with a Magic Mirror, reach a depth of 0ft, or die), so they need to be dealt with eventually.

Fire Imps require a target space of 4 blocks high by 3 blocks wide to teleport into a location, while they can spawn in a 3 block high by 2 block wide space that is off screen.
