A Missing Page is a trinket.
- Grants a chance to deal damage to all enemies in the room on being hit, similar to The Necronomicon.
- The activation chance depends on the luck stat, and goes up to around 50% with very high Luck (between 50-60 luck).
- This item is not triggered when a hit is absorbed by Holy Mantle, making it useless while playing with The Lost.
- The Necronomicon, A Missing Page, and Missing Page 2 are all references to the Necronomicon and its missing pages appearing in Evil Dead.
- Which, in turn, is a reference to the Necronomicon, a fictional grimoire appearing in the works of horror writer H.P. Lovecraft.
