Notes[ | ]

  • (except in Repentance) Re-rolling a monster will replace it with an entirely new one from any floor, making it dangerous to use early on in the game (as Isaac could get monsters from DepthsDepths or later).
  • (except in Repentance) The D10 will not reroll Bosses but can reroll monsters spawned by bosses.
  • (in Repentance) The D10 will not reroll friendly enemies.
  • Using this item can cause some rooms to become impossible to clear. Jumping or flying monsters may become trapped behind rocks after being rerolled, and therefore become unbeatable.
    • Sealed doors open after 2 minutes, though there are situations that can prevent this failsafe from triggering.
  • (in Afterbirth and Afterbirth †) Flying monsters will only be rerolled into other flying monsters, and ground monsters can only be rerolled into ground monsters. ( HorfHorfs are classified as ground monsters by the D10).
  • (in Repentance) Some invincible enemies will be rerolled, while others (including most Grimace variants) are completely unaffected.
  • Using this item in a room with Mom's HandMom's Hand can be very dangerous, as unless they have already landed, they will be directly on top of Isaac, resulting in the new monsters spawning directly on top of Isaac, instantly dealing contact damage.
  • Using this item, then exiting the room, such as by teleporting or a bombed door, will cause the enemies to be in their original forms upon Isaac's return.

Synergies[ | ]

  • (in Repentance)Collectible Book of Virtues iconBook of Virtues: Spawns orange wisps in the middle ring. Tears shot from these wisps have a 10% chance to replace enemies with their weaker variants.
  • (in Repentance)Collectible Car Battery iconCar Battery: Weakens affected enemies twice.

Interactions[ | ]

  • (except in Repentance)Broken RemoteBroken Remote: Using D10 while holding this will first teleport Isaac, and then reroll the enemies in the new room.

Trivia[ | ]

  • Despite being a dice item, D10 is not an unlock.
  • (in Repentance) D10 was voted the worst quality 0 item in the game in a poll on the Binding of Isaac subreddit, resulting in its consequent rework and upgrade to quality 1.

Bugs[ | ]

Bug Bug! (in Rebirth and Afterbirth) The D10 can reroll the Suture half of Boss Blighted Ovum ingameBlighted Ovum.
Bug Bug! (in Rebirth and Afterbirth) Using this item on any monster with several pieces will reroll every piece into a monster. Mr. MawMr. Maw and Boss Gemini ingameGemini's cord dots are considered pieces, each turning into a new monster.
Bug Bug! (in Rebirth and Afterbirth) Rarely, a monster can be rerolled into the mask half of the Mask HeartMask + Heart enemy, and the mask will die instantly.
Bug Bug! (in Afterbirth and Afterbirth †) The Attack FlyAttack Fly, SwarmSwarm, and Camillo Jr.Camillo Jr. enemy can't be rerolled (even though monsters can be rerolled into them).
Bug Bug! (except in Repentance) Using this item in a room with Stone GrimaceStone Grimaces will turn them invisible. They will not fire, but the space they occupied will prevent Isaac from moving through it like an invisible wall.
Bug Bug! (in Repentance) D10 and items related to it can reroll frozen enemies into alive ones, effectively bringing them back to life.
