Cursed Skull

Cursed Skull is a trinket.

Effects

 * If Isaac has less than one full Red Heart after taking damage, he will be immediately teleported to a random room.
 * The teleportation happens only at half a heart or less left, regardless of health type. Empty Bone Hearts are not counted as health even if they can absorb a hit.

Interactions

 * : Provided Scapular can always trigger, grants effective immortality, as the soul heart is always given before the teleport takes place.
 * +: Grants true immortality, plus one hit on the soul heart, allowing the player to get hit once before teleporting.
