Fistula is a boss that can appear in the Cellar.

Behavior[edit | edit source]

  • Moves around the room slowly, bouncing off the walls.
  • When enough health is depleted, the one large Fistula breaks into four medium Fistulas.
  • Each of the four medium Fistulas break into two small Fistulas.
  • After the smallest Fistulas are defeated, they spawn Chargers unless they are over a pit or other obstacle.
  • All stages of Fistula will do 1 red heart of contact damage.

Champion Versions[edit | edit source]

  • Black: Spawns Boom Flies instead of Chargers. Each piece travels much slower, and splits into three medium Fistulas as opposed to the original's four.

Gallery[edit | edit source]
