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.
== Notes ==
* Fire Imps require a target space of at least four vertical air spaces and three horizontal air spaces to teleport into a location. Despite this, they only need three vertical air spaces and two horizontal ones to spawn.
* Fire Imps spawn more frequently as long as there are less than four other enemies on the screen.
== Tips ==
* The Fire Imp can be stunlocked with many different minions, as their repeated attacks prevent it from firing.
* When farming for the Obsidian Rose, it can be useful to place a Water Candle and drinking a Battle Potion to boost the Fire Imps spawn rate.
== Trivia ==
* The Fire Imps dropping the Plumber's Hat may be a reference to 's ability to shoot fireballs when getting a Fire Flower power-up, similar to the Burning Spheres that Fire Imps shoot. This is further supported by the Obsidian Rose that they drop, which references the Fire Flower power-up.
* Fire Imps could originally drop a Green Cap in the . Since an unknown update, this is no longer the case.
* The Slice of Hell Cake's description implies that their teleportation ability is not innate and must be learned.
