Monster Manual is an activated item. It is a book with a centaur, horse, and a dragon on its cover.

Effects

Upon activation, Satan's laugh will be heard and a random Familiar (even locked familiars) will spawn and help Isaac for the current room. Can spawn one of the following:

Synergies

  • Combined with items such as the 9 Volt, Habit, etc. can allow Isaac to have an army of familiars following him. Using this in a boss room can cause the boss to lose health very rapidly.

Trivia

  • The item and its graphics are both references to the D&D Monster Manual.
  • Its presence is related to the statement that D&D is a gateway to Satanism.
  • The secret pop-up for this item misspells "Monster Manual" as "Monster Manuel".

Bugs

  • More than 3 orbitals may be active as a result using this item; this may have been done to avoid deleting old orbitals by accident, or could have been simply overlooked.
  • Will spawn "undefined," if too many familiars are present on screen.
