Mordenkainen’s Fiendish Folio Volume 1: Monsters Malevolent and Benign, which benefits Extra Life, is an update of eighteen different 1st Edition monsters to 5th Edition rules. What was old is new again with the release of a new book from WotC onto the DM’s Guild. Indeed, many famous monsters, like the Githyanki and Githzerai, or the Slaad, would have their first introduction to the game in this book–which was assembled in part from White Dwarf’s ‘Fiend Factory’ column. In August 1981, the AD&D Fiend Folio brought to D&D an influx of monsters of all shapes and sizes, and more importantly, many of which were designed by players and DMs who had been quietly brewing up their own beasts at home. The Fiend Folio has long been home to some of D&D’s stranger monsters–now a bunch of 1st Edition creatures are getting a 5th Edition facelift.
