Expansion Pack is an unlockable trinket added in The Binding of Isaac: Repentance.
Effects
- Upon use of an activated item, activates the effect of another random activated item.
- The random effect is any activated item with a charge time of 1 or 2 rooms (with the exception of Metronome and D infinity). View the page on activated items for a complete list.
- Timed recharge and infinite use items trigger the effect once per room. Re-entering the room will allow Expansion Pack to trigger again.
Notes
- Effects from one time use, timed recharge, and infinite use item effects will not be produced by Expansion Pack.
- Dead Sea Scrolls qualifies for Expansion Pack as its charge time is 2 rooms. This may result in activations of items not normally selectable by Expansion Pack.
- If an item like Bob's Rotten Head or Shoop da Whoop! is selected, firing it will be counted as another item use and activate Expansion Pack a second time.
Trivia
- Expansion Pack can select Glowing Hourglass, preventing Expansion Pack from triggering another active item effect as it reverses time setting the effect back to the Glowing Hourglass effect. This allows for infinite uses of Glowing Hourglass.
