Fire Imp

The Fire Imp is an uncommon caster enemy found only in the The Underworld. It fires Burning Spheres, which travel through blocks and have a chance to inflict the On Fire! debuff. The Burning Spheres can easily be destroyed by hitting them with any weapon, minion, or damage-dealing tool or pet.

Like all casters, the Fire Imp will follow the pattern of firing three times, pausing for several seconds, and teleporting to another location on the screen.
