Added in Repentance

Eraser is an activated item added in The Binding of Isaac: Repentance.

Effects[]

  • On use, Isaac holds an Eraser above his head, which can be thrown in any cardinal direction. The Eraser instantly kills the first monster it hits, despawning all enemies of that type in the room and for the rest of the run.
    • Deals 15 damage to bosses. If fatal, erases the boss for the rest of the run.
  • Can only be recharged by entering a new floor. Batteries and most other methods of recharging have no effect.

Notes[]

  • Erased enemies and bosses appear as a brief pink puff of smoke. Any on-death effects are not checked.
    • The Seven Deadly Sins minibosses and Angels will still drop their respective pickups or items.
    • If used on multistage bosses like Hush or Ultra Greed, erasing the first phase skips any further phases.
  • Has no effect on invincible enemies, such as Stone Grimaces, lowered Hosts, or Eternal Flies.
  • Bulbs can steal charges from the Eraser.
  • Erased enemies and bosses will remain erased if a Victory Lap is started.
    • Erased enemies and bosses will also remain erased if items such as 15►R Key R Key or 15►Genesis Genesis are used.
  • Entities such as Ultra Greed Coins or Little Horn's Dark Balls are considered enemies and can be erased.
  • It is possible to erase Chargers, rendering Chubbers unable to attack.
  • Erasing Polties will render Haunted Chests harmless, but may make some rooms impossible to complete without bombs or flight as they rely on a Polty clearing a path.
  • Each floor traveled up during the Ascent will recharge the Eraser.

Synergies[]

  • 15►Angelic Prism Angelic Prism: Throwing the Eraser through the Angelic Prism will cause it to split into four.
  • Bethany Bethany / Tainted Bethany Tainted Bethany: Soul and blood charges can be used with the Eraser, allowing multiple uses per floor.
  • 15►Blood Puppy Blood Puppy: Throwing the Eraser at an enraged Blood Puppy (second stage) will 'erase' its enraged form, keeping it permanently tame.
    • Throwing the Eraser at its third stage will make it cycle through its normal and second stage as it kills enemies.
  • 15►Glowing Hour Glass Glowing Hour Glass: Using Glowing Hour Glass to return to the previous floor will keep the charge Eraser received from entering the next floor.
  • Tainted Jacob Tainted Jacob: Successfully dealing the final blow to Dark Esau with the Eraser will remove him for the rest of the run. Tainted Jacob will not be turned into Lost mode.
  • 15►Void Void: An eraser can be thrown with each use of Void after absorbing it, allowing multiple uses per floor.

Interactions[]

  • 15►Book of the Dead Book of the Dead/15►Poke Go Poke Go/Polished Bone Polished Bone: Enemies spawned by these items will not spawn if that type was erased, potentially rendering them useless.
  • 15►My Shadow My Shadow: Erasing a Charger will prevent all newly created friendly Chargers from spawning, rendering the item useless. The item spawns a normal Charger before changing it to the special My Shadow variant.
  • 15►Number One Number One: Lowers the Eraser's range drastically, making the item much more difficult to use. Range increases do not negate this.
  • 15►Sharp Plug Sharp Plug: Attempting to recharge the Eraser with the Sharp Plug hurts Isaac for half a heart without recharging the item.

In-game Footage[]

Bugs[]

Bug Bug! If this item kills Dogma during its first phase, it will treat the room as a regular room clear, dropping an consumable, but with no doors to walk out of, softlocking the room. However, this will not occur if you erase the television, instead skipping straight to its second phase. If used on the second phase, Isaac will also be stuck in the boss room.
Bug Bug! Using this item to erase the chain of The Visage will make the boss unkillable.
Bug Bug! Using this item with with the Butter! trinket and letting it cycle (e.g playing Tainted Isaac), will cause the item to regain its charge giving infinite uses
Bug Bug! If used to kill the Mom's Heart leading to Corpse, it will not count it as a kill, preventing progress on the path.
