Starting Effects

Flying
Can fly over rocks, holes, and poop. Ignores damage from floor spikes and pools of hazardous liquid. Can still be damaged by bombs, red poop, enemies, and projectiles.

Special
Cannot pick up Hearts of any kind and cannot have health increased. Damage taken results in a death. Revive items function normally.

Note that as a side effect, all Devil Room items can be taken without cost.


How to Unlock
You must die as specific characters and by specific means. These four can be done in any order (in one play session) as long as there are NO other losses in between. Currently, seeds will work. The following order is recommended:
    
As Isaac, die by a Mulliboom's explosion in either the Basement or Cellar (Seed: JTMD EZPF, go down).
    
As Magdalene, die by your own bomb in either the Caves or Catacombs.
    
As Judas, die by Mom. Easiest way is to damage self to half a heart before entering then running to middle of room.
    
As Azazel, die by Satan during his second phase (after The Fallen, before the hooves) in Sheol.

Mulliboom:
Appears rarely. Slightly more common in Cellar. Setting difficulty to Hard adds a few more rooms with Mullibooms to the generation list, making them a bit more common to encounter.

You can use your own bombs to blow up doors to get through rooms with lots of enemies without killing them, saving some time.

Unlike other explosions, these deal only a half heart of damage.
