'M
Effects
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.(Guppy's Paw) Guppy's Paw, (Jar of Flies) Jar of Flies, (Bob's Rotten Head) Bob's Rotten Head, (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 (Magic Fingers) Magic Fingers, (Potato Peeler) Potato Peeler, (Converter) Converter, etc.) can be rerolled even if Isaac doesn’t have the resources necessary to use them.
- The only exception is (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 (Bob's Rotten Head) Bob's Rotten Head, (Black Hole) Black Hole, (Eraser) Eraser, (Spin to Win) Spin to Win, (Mom's Bracelet) Mom's Bracelet, etc.) must be properly used to have their charge expended.
- ‘M cannot reroll active items into (Broken Shovel) Broken Shovel, (Mom's Shovel) Mom's Shovel, (Bag of Crafting) Bag of Crafting, (Hold) Hold, (Sumptorium) Sumptorium, (Flip) Flip, or (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.
- (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.
- (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.
- (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.
- Butter!: The active item is rerolled before being dropped.
- (Car Battery) Car Battery: The current active item is used twice before it is rerolled.
- (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.
- (Friendly Ball) Friendly Ball / (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.
- (Glowing Hour Glass) Glowing Hour Glass: Glowing Hour Glass rewinds time before the reroll goes through, preventing it from happening.
- (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.
- (Notched Axe) Notched Axe: The item will be rerolled once it runs out of durability.
- (Schoolbag) Schoolbag: Only the primary item is rerolled.
