Boom Flies roam around the room diagonally, dealing touch damage and exploding with a large blast radius upon death. Skatole slows them down, but they remain dangerous. They also spawn from blue champion bosses such as Fistula.
Variants[edit | edit source]
Red Boom Fly[edit | edit source]
Red Boom Flies roam around the room diagonally, dealing touch damage and exploding into 6 directional blood shots upon death. Skatole will only slow down their movement.
Drowned Boom Fly[edit | edit source]
Chance To Replace Boom Flies and Red Boom Flies In Flooded Caves
Drowned Boom Flies fly around the room diagonally, dealing contact damage. Upon death, they explode and release 4 blood shots in the cardinal directions, occasionally spawning a Drowned Charger.
If a Drowned Boom Fly dies while over an obstacle or pit, the Drowned Charger will not be spawned.
