The Blurb walks slowly towards Isaac and fires a chaotic burst of tears if they get close or take enough damage. After firing their tears, they act like regular Gapers and chase Isaac faster than before, attempting to deal contact damage. In the fight against Mausoleum Mom's Heart, bloody versions of Blurbs with pinker skin can be summoned during the battle.

The Heretic

The Fanatic is a cultist which appears exclusively in the boss fight against the Heretic. At the beginning they are seen in a group of 5 on the edges of a large purple pentagram on the floor, chanting and kneeling towards the center as the Heretic emerges. They are covered with shields and can not be killed until the Heretic is done spawning. Once they are done, they will chase Isaac while shooting homing tears periodically. Upon death, they have a chance to turn into Pacers or Gushers like normal Gapers.

Trivia[ | ]

  • Fanatics resemble Exorcists when summoning the Heretic.
