Synergies[edit | edit source]

  • The Battery The Battery

    : 2 Charmed Deliriums can be spawned, but it takes 24 rooms or 2 Little Batteries to fully recharge.
  • Car Battery Car Battery

    : 2 random bosses are spawned at the same time, making the item valuable during boss fights and coincidentally replicating a Double Trouble boss fight.
  • Charged Baby Charged Baby

    : The familiar will spawn Little Batteries to recharge the item easily.
  • Void Void

    :  When used to absorb Delirious it decreases the charge time to 6, halving the time to recharge.

Notes[edit | edit source]

  • If multiple bosses are spawned in one room with Car Battery Car Battery

    or battery pickups, the bosses can try to kill each other.
  • If the spawned boss can leave creep, the creep can damage Isaac.
  • In 1x2 rooms, Ultra Greed can spawn. He'll lock all doors and target Isaac. He can't damage Isaac by himself, but his summons can.
  • Unlike Mega Blast 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.
  • Enabling "debug 8" in the Debug Console (which grants infinite item charges) and continually spawning bosses can crash the game.
  • Delirious has a 60% decreased item pool weight, making it less likely to appear than other collectibles.

Bugs[edit | edit source]

Bug Bug! If Delirious is used during the Delirium fight and the charmed boss is killed, it will act as if Delirium was killed, but no chest will spawn.
Bug Bug! If Delirious is used in the Mega Satan Room before stepping on the pentagram, the room will change and Mega Satan will be unable to spawn. Exiting and continuing the run fixes this.
Bug Bug! If a Pink Champion Polycephalus is spawned by the item, one will have the Delirium skin and the other will have the normal Polycephalus skin.
Bug Bug! If Lokii is spawned by the item, one will have the Delirium skin and the other will have the normal Lokii skin.
Bug Bug! If a Pink Champion The Cage is spawned by the item, one will have the Delirium skin and the other will have the normal The Cage skin.
Bug Bug! If a boss is summoned by Delirious in a boss room and it dies before the enemy boss, "The Calm" (the "boss defeated" music) will begin to play.
Bug Bug! If Scolex is spawned by this item (only in Hard Mode or Greedier Mode), sometimes, it will spawn a gray tinted Scolex with the appearance of The Frail in its second phase.
