Notes[ | ]

  • The item does not replace hearts, pills and chests.
  • The item can also replace Troll BombTroll Bombs and Mega Troll BombMega Troll Bombs that are not used as attacks, i.e. generated as room rewards, chest contents and such.
  • The pickup replacement is applied retroactively when the item is collected: any appropriate pickup already existing on the current level may be replaced by a sack.
  • (in Rebirth and Afterbirth) Sacks on each floor tend to have the same contents, which can be taken advantage of if cards are involved.
  • (in Repentance) Picking up a Golden PennyGolden Penny may spawn a sack instead of another Golden Penny.
  • (in Repentance)Cracked KeyCracked Key in the Ascent can be replaced by a sack, thus it is not recommended to take the item if you're going to unlock a tainted character.
