D20

Effects

(Removed in Repentance) The empty chest object that is left behind after opening any kind of chest can be re-rolled.
On (Chest) 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) Shop.
Re-rolling pickups duplicated by (Rune of Jera) Rune of Jera, (Added in Afterbirth) Diplopia and (Added in Afterbirth †) Crooked Penny will result on both the original item and the duplicate being the exact same pickup.
- (Added in Repentance) Can re-roll both items created by Options?, but only one can still be taken.
(Added in Repentance) Golden trinkets rerolled by D20 will cause the resulting pickup to have the golden effect applied to it. If this is a trinket, the affected trinket will act as a normal golden trinket would, otherwise the gold effect will do nothing and will disappear upon leaving and reentering the room.
- Additionally, items spawned by chests with the gold effect applied will be golden as well, however other pickups dropped by chests will not be.
(Added in Repentance) Can reroll coins dropped by (Tainted Keeper) Tainted Keeper into other pickups, but they will still disappear if not picked up quickly.

(Added in Repentance) Book of Virtues: Spawns wisps in the middle ring. In addition to summoning its specific wisp, instead of rerolling pickups, it will destroy all pickups in the room and has a chance to give a random wisp for each pickup destroyed.

(Added in Repentance) When used to reroll pickups in (Tainted Keeper) Tainted Keeper's special shops, pickups may be rerolled into items instead.
