Notes[edit | edit source]

  • The empty chest object that is left behind after opening any kind of chest can be re-rolled.
    • Added in Repentance Empty chests cannot be re-rolled.
  • On The Chest The Chest and Dark Room Dark Room, the re-rolled chests will contain items.
  • Cannot re-roll pickups into Lil' Batteries, but can re-roll pickups into Grab Bags which can contain Lil' Batteries.
    • Added in Repentance Can re-roll pickups into Lil' Batteries and other battery pickups.
  • It can re-roll pickups into chests.
  • It can re-roll pickups in the Shop.
  • Re-rolling pickups duplicated by Jera will result on both the original item and the duplicate being the exact same pickup.

Strategy[edit | edit source]

  • In Greed mode, the D20 is a one-item game breaker as long as the Shop has a Lil' Battery available. Leave behind as many coins and pickups in the arena as possible. After using the D20, avoid opening chests until you have recharged the item. Avoid collecting things that do not spawn pickups, help buy Lil' Batteries, or help open chests. This can often be repeated indefinitely, leading to collecting coins, bombs, and many pedestal items.
    • Added in Repentance Due to how the D20 interacts with the Added in Repentance15►Book of Virtues Book of Virtues, this strategy will not work with Bethany, as using the D20 while playing as her will destroy all pickups in the room.
      • However, this can be avoided by removing Book of Virtues using Butter! or The Stars? card.
    • Added in Repentance D Infinity can also be used if it is found.
