Exorcist

Exorcists are enemies found exclusively in the fight against The Heretic, and can never be found naturally. They take the appearance of a Gaper with its head's skin rolled down, revealing its skull.

During the fight with The Heretic they are found in a group of 5 and are stationary and invulnerable due to being shielded. After The Heretic has been summoned they transform into Fanatics.

If spawned by itself, it will start to walk towards Isaac, occasionally spawning a single Lil' Haunt. It will try follow that most recently spawned Lil' Haunt and use it to shield itself and will only spawn another Lil' Haunt once the previous has been killed by Isaac. It will also run away from Isaac once its designated Lil Haunt has been killed prior to spawning another.

After an enemy dies, it will leave behind a small red spirit, sometimes, an Exorcist will walk over to one of the red spirits and revive it as a Lil' Haunt, similar to Rag Man or a Cultist.

All red spirits will disappear once an exorcist dies.
