Fiend Folio Wiki

Welcome to the Official Fiend Folio Wiki!

The official wiki for the Fiend Folio: Reheated MOD! A grand community-made expansion for The Binding of Isaac: Repentance which adds hundreds of new foes, items, and rocks from people who've helped bring you Revelations, Retribution, The Devil's Harvest, Alphabirth, Septic Shock, and more?
Make sure to join our official Cornmunity Discord Server for teasers on upcoming updates, or just talk about the MOD!
