Bad Memory is a consumable item acquired by using the ITEM ACT during the encounter with Memoryhead. Using it depletes one HP unless the protagonist's HP is three or lower, in which case it restores all HP.
- You threw the Bad Memory away. But it came back. [Drop]
- It is one of the items in the game which cannot be dropped. This makes the damage reduction it gives unavoidable unless the protagonist leaves it in free inventory space or if they consume it while their HP is under three.
