Behavior[edit | edit source]
Ultra Pestilence spawns with a swarm of flies that hover around itself. In its first phase, Ultra Pestilence has two attacks which it alternates between.
- Ultra Pestilence fires a large projectile in an arc at Isaac's position. Upon landing in the lava below, it creates a poisonous cloud pillar that will damage Isaac if he stands inside for too long, creates a pillar of projectiles that shoot upwards from the lava, and creates three additional projectiles that shoot upwards from the lava on both sides of the pillar. Ultra Pestilence uses this attack three times before using its other attack.
- Ultra Pestilence fires a large maggot from its eye which flies across the screen, wrapping around three times. Before it completes a fourth wrap, it reverses direction, wrapping around three more times before reentering Ultra Pestilence's eye.
During its second phase, Ultra Pestilence loses its head, naturally generates flies around itself and uses two attacks.
- Ultra Pestilence fires a spray of projectiles which rain down on the area in front of it.
- Rarely, Ultra Pestilence's steed will spawn a ball of flies which moves towards Isaac. Attacking this ball of flies will spawn additional flies.
