Binding of Isaac: Rebirth Wiki

This article is about the small odd mushroom. For the larger mushroom, see Odd Mushroom (Large). For other uses, see Odd Mushroom (Disambiguation).

Odd Mushroom is a passive item.

Effects[ | ]

  • +1.7 tears.
    • Additional copies only grants +0.7 tears.
  • +0.3 speed.
  • -0.4 damage.
  • x0.9 total damage up multiplier.
  • (except in Rebirth) This item belongs to the Fun GuyFun Guy set. Collecting three items from this set will transform Isaac into a walking mushroom.

Notes[ | ]

  • There are two collectible items in the game named Odd Mushroom; they can be told apart from the sprites.
  • This item's damage multiplier works differently than other items in the game: instead of directly multiplying the damage stat, it multiplies the total added damage from other items. As a result, flat damage upgrades aren't affected by Odd Mushroom.
    • Multiple copies of the item will grant a speed and fire rate boost with no additional decrease in damage.
  • Isaac's head becomes smaller as a result of this item. This is purely cosmetic.
