Incompatibility
Certain mods can cause issues with Fiend Folio when used in conjunction, and therefore should be met with caution. The following lists will be updated sporadically.
Custom Health API
The following mods do not currently work with Custom Health API, a vital feature of Fiend Folio: Reheated, and may trigger a warning message to appear in-game. You should disable these mods when playing Fiend Folio:
Miscellaneous
The following mods do not currently work with Fiend Folio: Reheated in one way or another. You should disable these mods while playing lest you encounter major issues:
- Genesis+ Septic Shock: The Reheated update will not work with Septic Shock, as the latter has not been ported to Repentance — however, it is still compatible in the Afterbirth+ version of Fiend Folio, even having added their own special reskinned enemies to appear in the Septic which have still been left over in Reheated.
- Main article: Septic Enemies
The following mods have noteworthy bugs but otherwise work fine. You should decide for yourself whether these issues are important enough to disable the mod in question:
- More Dr. Fetus Synergies: This mod messes with the functionality of
Angelic Lyre if the player has Dr. Fetus.
Fiend Folio has "consumed" a few smaller mods into itself! This means that if you have those mods AND Fiend Folio enabled, you should consider disabling said mods to avoid weird bugs, or redundancy such as duplicate items in the game:
