Effects[ | ]

Notes[ | ]

  • The chance to get Collectible A Lump of Coal iconA Lump of Coal or Collectible The Poop iconThe Poop is determined by Luck using this formula:
    • A table showing an example is below. There's no cap, with diminishing returns. At 88 Luck the chance drops to 2%.
Luck Item Pool Poop/Coal
-10 0% 100%
0 83.3% 16.6%
8 90% 10%
  • A Lump of Coal and The Poop are fixed drops, and cannot be changed by having Collectible Chaos iconChaos, holding NO!NO!, and other similar effects.
  • Spawning The Poop will create a poison cloud, as if having used Collectible The Bean iconThe Bean, down to matching the former item's effects.

Synergies[ | ]

  • (in Repentance)Collectible Book of Virtues iconBook of Virtues: Spawns a random wisp. For the rest of the run, a random wisp spawns after clearing a room if the one given by the item was destroyed, including the replacement wisps given by this effect.
  • (in Repentance)Collectible Damocles iconDamocles: When Damocles is activated, a second item will be spawned with adherence to the item pool for the current room. Even if Mystery Gift "fails" and spawns either Collectible The Poop iconThe Poop or Collectible A Lump of Coal iconA Lump of Coal, a second item from the current room's item pool will always be rewarded.

Interactions[ | ]

  • Collectible Void iconVoid: Like all single-use active items, this item cannot be absorbed by Void. Instead, it will consume and use the Mystery Gift.
