Abilities that can cause this interaction include: It will also burst into 8 medium Fistulas in a radius that disappear quickly each of these can also deal damage to Mother or Isaac. Successfully reflecting the Fistula 6 times will cause it to be destroyed upon contact with Mother, dealing damage to and briefly stunning her. This Fistula can be reflected back towards Mother through the use of a variety of melee-based attacks, each reflect causing the Fistula to glow brighter.These small Fistulas travel a short distance before bursting and spawning a Small Maggot. Each medium Fistula flies until it collides with a wall, sending out 2-3 small Fistulas and being destroyed in the process. Mother repeats this several times, causing the Fistula to gradually gain speed, before slamming a hand down on the mass, crushing it and sending 3 medium Fistulas outwards. Mother swipes the Fistula towards Isaac whenever it travels close to one of her hands and releases 2 lines of 8 projectiles when it collides with the bottom wall. Occasionally, Mother spits out a unique Fistula at Isaac that bounces off walls.Small Maggots that land on top of Mother's hitbox do not spawn.One of Mother's hands slams the ground, releasing streams of projectiles in a radius and spawning Small Maggots.One of Mother's arms releases trails of projectiles that move across the arena in a wave pattern, eventually homing in on Isaac.The knife emits projectiles horizontally while travelling and a burst of many projectile lines in a radius upon impacting the back wall. One of Mother's hands grabs a knife and throws it directly downwards.Her face and hands can all be attacked to deal damage to her, and she uses them separately in her attacks: Mother begins the fight attached to the top of the room and is stationary, similar to Mega Satan. Walking into it drops Isaac down into the arena where Mother is fought. Upon entering the boss room in Corpse II, the room is empty except for a hole in its center.
