Fiend Folio is a mod for The Binding of Isaac that adds tons of new enemies/monsters, new items, new bosses, new unlocks & achievements and all sorts of new rooms, graphics, sounds, and worthy funny memes that will surely improve your overall experience! Fiend Folio Reheated is an expansion to the original mod that is officially available and fully compatible for The Binding of Isaac Repentance.
If you're tired of Brimstone, Death Certificate, Pyromaniac, Proptosis, C Section, Technology, Ipecac, Soy Milk, G FUEL, Godhead, Birthright, Sacred Heart, Crown of Light, Planetarium items, standard devil and angel room stuff, TMTRAINER, Guppy, why not try Pyromancy, Black Moon, Nil Pasta, GMO Corn, Peach Creep, Black Lantern, Crucifix and a variety of other items this mod has to offer?
Why restrain yourself to fighting Delirium, Blue Baby, Mother, Mom, The Beast, Dogma, Baby Plum, Monstro and The Bloat, when you can face Buck, Buster, Meltdown, Kingpin, Gutso, Luncheon (not an Eevee evolution, this ain't Pokemon!), Warp Zone, Cacophobia, Gravedigger, Psion, and much more!
Forget about the boring ol' The Lost, Keeper, Jacob and Esau, Judas, Blue Baby, Bethany, Azazel, The Forgotten, and give Fiend, Golem and China a try! Also includes their tainted versions!
