Notes[]

  • The active item given by ‘M will always have no charges, regardless of what the previous active item was and whether or not it was overcharged.
  • Rerolling into active items counting towards transformations (e.g. 15►Guppy's Paw Guppy's Paw, Added in Afterbirth15►Jar of Flies Jar of Flies, 15►Bob's Rotten Head Bob's Rotten Head, 15►The Bible The Bible etc.) will not be counted towards said transformation, regardless if Isaac puts it back down and picks it back up.
  • Active items that have costs associated with using them (such as 15►Magic Fingers Magic Fingers, Added in Afterbirth †15►Potato Peeler Potato Peeler, 15►Converter Converter, etc.) can be rerolled even if Isaac doesn’t have the resources necessary to use them.
    • The only exception is Added in Repentance15►Golden Razor Golden Razor: Isaac must have the 5 cents necessary to use it in order for it to be rerolled.
  • The item’s charge must be expended for it to be rerolled; items that can be used without spending their charge immediately (such as 15►Bob's Rotten Head Bob's Rotten Head, Added in Afterbirth †15►Black Hole Black Hole, Added in Repentance15►Eraser Eraser, Added in Repentance15►Spin to Win Spin to Win, Added in Repentance15►Mom's Bracelet Mom's Bracelet, etc.) must be properly used to have their charge expended.
  • ‘M cannot reroll active items into Added in Afterbirth †15►Broken Shovel Broken Shovel, Added in Afterbirth †15►Mom's Shovel Mom's Shovel, Added in Repentance15►Bag of Crafting Bag of Crafting, Added in Repentance15►Hold Hold, Added in Repentance15►Sumptorium Sumptorium, Added in Repentance15►Flip Flip, or Added in Repentance15►Recall Recall.
  • Active items 'M rerolls into is fixed per seed. This means the same active item on the same seed while holding 'M will always reroll into the same other active item every time.

Interactions[]

  • One-time use items: The item disappears before it can be rerolled.
    • Added in Afterbirth †15►Sacrificial Altar Sacrificial Altar: If Isaac has no eligible familiars, the altar can be rerolled without being consumed.
  • Added in Repentance15►Book of Virtues Book of Virtues: If an active item is combined with the Book, only the active item is rerolled; the Book remains unchanged. If no active item is combined with the Book, the Book will be rerolled on use. ‘M also cannot give Book of Virtues, as it is considered a passive item.
  • 15►Breath of Life Breath of Life: Breath of Life is rerolled once the charge is fully expended. After one second, Isaac starts getting hurt as if he was still using Breath of Life until he leaves the room.
  • Added in Repentance15►Broken Glass Cannon Broken Glass Cannon: The item is rerolled instead of turning into Glass Cannon. This item can also be given by ‘M directly.
  • Added in Afterbirth †Butter! Butter!: The active item is rerolled before being dropped.
  • Added in Afterbirth15►Car Battery Car Battery: The current active item is used twice before it is rerolled.
  • Added in Repentance15►Esau Jr. Esau Jr.: Isaac will transform into Esau Jr. if ‘M rerolls Isaac’s active item into Esau Jr. However, he will not transform into Esau Jr. if the item itself is used.
    • As the original character will be holding ‘M, Esau Jr. must be used twice for it to be rerolled.
  • Added in Afterbirth15►Friendly Ball Friendly Ball/Added in Afterbirth †15►Moving Box Moving Box: As the item must be used twice to have its intended effect, rerolling it on the first use will prevent it from being used to its full effect.
  • Added in Afterbirth15►Glowing Hour Glass Glowing Hour Glass: Glowing Hour Glass rewinds time before the reroll goes through, preventing it from happening.
  • Added in Repentance15►Magic Skin Magic Skin: Items given by Magic Skin cannot be Magic Skin even if it’s rerolled on use. However, as Isaac will not be holding Magic Skin after using it, it will be able to replace future items after being rerolled.
  • 15►Notched Axe Notched Axe: The item cannot be rerolled by either using it or depleting its charge.
  • Added in Afterbirth †15►Schoolbag Schoolbag: Only the primary item is rerolled.

Strategy[]

  • Once ‘M gives a good active item, it can be dropped so that it can be continually used without it getting rerolled.
  • Some active items have effects that can be harmful to Isaac when used; consider if rerolling your active item is worth the risk of getting an item that you can’t reroll (either at all or without hurting your run).
    • Added in Repentance15►Alabaster Box Alabaster Box is especially noteworthy in that it not only cannot be rerolled, but will also preventing Isaac from gaining soul hearts until he uses or gets rid of it.

In-game Footage[]

Trivia[]

  • Like 15►Missing No. Missing No., the name 'M is a reference to a glitch from the Generation I Pokémon games, often thought of as a counterpart to MissingNo. itself. This is also referenced by its appearance, as random jumbles of pixels is very similar to the corrupted sprites you would see from a sprite error in Generation I Pokémon games.
  • The description is a combination of Broken Remote Broken Remote and 15►The D6 The D6's description, "It's broken" and "Reroll your destiny".
