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.
Erased enemies and bosses appear as a brief pink puff of smoke. Any on-death effects are not checked.
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.
Number One: Lowers the Eraser's range drastically, making the item much more difficult to use. Range increases do not negate this.
Sharp Plug: Attempting to recharge the Eraser with the Sharp Plug hurts Isaac for half a heart without recharging the item.
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.
Using this item to erase the chain of The Visage will make the boss unkillable.
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
