Red Boom Fly is a red type of the Boom Fly with swollen cheeks first encountered in Chapter 2.
Behavior[]
They move identically to regular Boom Flies, but will shoot 6 projectiles on death instead of exploding. The projectiles always have a set trajectory pattern so you can position yourself for safety.
Champion Variant
[]
Eternal Red Boom Flies shoot an extra wave of significantly more tears on death as well as the first wave of 6.
This variant was added in the Eternal Edition update but exclusively found in Hard Mode.
Notes[]
- Red Boom Flies can replace Boom Flies in any floor. They can also be spawned by Lokii and the blue champion variant of Fistula.
Bugs[]
- If you kill a Red Boom Fly before it moves, it will explode like a normal Boom Fly.
