Defeat Delirium for the first time as any characterDelirious

Delirious is an unlockable active item added in Afterbirth †.

Effect

• Upon use, spawns a Delirium in a form of a charmed boss.
• Changes the appearance of the current room so it looks like a different chapter.

Notes

• If multiple bosses are spawned in one room with Car Battery or battery pickups, the bosses can try to kill each other.
• Sometimes bosses don't spawn because of grid entities getting in the way. When this happens the upper door appears to have friendly particles.
• Unlike Mega Blast, this item can be charged with a single Little Battery.
• It is possible for Hush to spawn, despite Delirium not transforming into Hush during its boss battle.
• If a boss summons monsters, the monsters will be charmed and will follow Isaac out of the room.
• Delirious has a 60% decreased item pool weight, making it less likely to appear than other collectibles.
