Boom Fly

Boom Flies roam around the room diagonally, dealing contact damage and exploding with a large blast radius upon death. Skatole slows them down, but they remain dangerous.

Variants[]

Red Boom Fly[]

Red Boom Flies roam around the room diagonally, dealing contact damage and releasing 6 blood shots in all directions upon death. Skatole will only slow down their movement.

Drowned Boom Fly[]

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.

Dragon Fly[]

Dragon Flies fly around the room diagonally, dealing contact damage. Upon death, they spawn 4 lines of fire in the cardinal directions.

Dragon Fly X[]

Dragon Fly X is identical to the Dragon Fly in behavior, but upon death, it spawns 4 lines of fire in the ordinal directions.

Bone Fly[]

Bone Flies fly around the room diagonally, dealing contact damage and firing bones at Isaac when they are lined up, similar to a Bony. Upon death, they shoot 3 evenly spaced bones (one of them aligned towards the closest cardinal direction to Isaac).

Sick Boom Fly[]

Sick Boom Flies fly around the room diagonally, dealing contact damage and trailing poisonous gas. Upon death, they explode into eight clouds of gas and release 6 green shots in all directions. The poison gas left behind upon death persists for much longer, but will dissipate when the room is cleared.

Tainted Boom Fly[]

Tainted Boom Flies are bigger and stronger versions of Boom Flies. They fly around the room diagonally, dealing contact damage. When near death, they will start to emit a cross-shaped glow; if they are not killed soon after, they will self-destruct and send explosions in a cross-shaped marker across the room.

Although they cannot be killed normally before their self-destruct sequence finishes, status effect damage such as poison is capable of killing them.

They are exclusive to the Ascent to Home.
