Behavior[edit | edit source]
Phase 1[edit | edit source]
- During the beginning of the fight, the Heretic is summoned by 5 Exorcists which are then turned into Fanatics.
Phase 2[edit | edit source]
- Lobs 7 projectiles that, after landing, burst into 6 fires that spread out in a radial pattern. The landing position of each projectile is marked on the ground, and the trajectory the fires spread in is fixed.
- The Heretic then follows up by launching itself towards Isaac creating a radial burst of 8 flames of fire where it lands. It will spend a short time readjusting its dislocated jaw before continuing to attack.
- The arena of the Heretic will always spawn a number of unlit Fire Places. The Heretic can light up 5-6 of them before firing a Brimstone laser that connects all of the lit fires. The order the Heretic lights each fire indicates what order the laser will follow.
- These can be extinguished with an explosion and will prevent Brimstone lasers from reaching said Fire Place.
- Dashes off-screen and turns invisible before charging in again, attempting to bite down on Isaac. It will chain this attack a total of 4 times, each time from alternating sides of the room.
- The Heretic will occasionally not finish the fourth charge, instead fading away and quickly charging in one final time from the other side of the screen.
- Upon death, the Heretic's firey eye drops down and sends out lines of fire in the cardinal directions.
