• Familiars spawned by Monster Manual last for the current room.
  • Familiars spawned by Monster Manual last for the rest of the floor.
• Familiars generated by Monster Manual do not contribute toward transformations.
• This item belongs to the Bookworm set. Collecting three items from this set will transform Isaac into Bookworm.

Notes

• It can spawn familiars not yet unlocked.
• If Cube of Meat or Ball of Bandages are spawned and Isaac already has either of those items, the level of these items will increase for the current room floor.
• Using Monster Manual is a good method to unlock achievements related to Super Meat Boy and Super Bandage Girl.
  • Using Monster Manual and enough Batteries, Super Meat Boy and Super Bandage Girl can both be achieved in the same run.
  • If Isaac does not already have the Cube of Meat or Ball of Bandages, Monster Manual can spawn a level 2 Cube of Meat or Ball of Bandages in one use.
• Mongo Baby will not copy familiars spawned by Monster Manual.
• Familiars spawned by Monster Manual cannot be rerolled into other items by D4 or D100.
• Box of Friends will not duplicate familiars spawned by Monster Manual.
• Tinytoma orbitals will persist between floors until they are all destroyed. They will not respawn outside of the floor they were generated in.
• The familiars summoned by Monster Manual are items with a monstermanual item tag.

Synergies

• Book of Virtues: Spawns wisps in the inner ring. The given wisps function similarly to familiars given by Buddy in a Box.

Interactions

• Sacrificial Altar: Summoned familiars can be sacrificed since they persist for the entire floor, even if Monster Manual isn't currently being held.

Trivia

• In the original The Binding of Isaac, due to a typing error this item was called "Monster Manuel". This has been corrected for Rebirth.
  • Monster Manual may sometimes display the misspelled name when picked up.
• Monster Manual is a direct reference to Dungeons & Dragons. Its appearance in the game closely resembles the Advanced Dungeons & Dragons First Edition Monster Manual.
  • The item being in the Devil Room pool is likely a reference to the moral panic surrounding the game in the 1980s.
