Development and release[]


The book was written by Don Turnbull. Art was provided by Chris Baker, Jeff Dee, Emmanuel, Albie Fiore, Alan Hunter, Russ Nicholson, Erol Otus, Jim Roslof, David C. Sutherland III, Bill Willingham, Polly Wilson and Tony Yates.

The Fiend Folio was the first AD&D book produced by TSR's British branch, TSR UK, Ltd., and the first official AD&D book by editor Don Turnbull. Production began while the Dungeon Masters Guide (1e) (1979) was being finalized.[1] The Fiend Folio was not part of Gary Gygax's original plans for AD&D when he announced the new game in Dragon #8 (Jul 1977).[2]

The majority of the monsters in the Fiend Folio were originally submitted for the column "The Fiend Factory", which began in Games Workshop's White Dwarf #6 (Apr/May 1978).[2] However, many had never actually seen print in "The Fiend Factory", as Turnbull had far more submissions that could be published in the magazine. According to Turnbull, the demand for more monsters from readers, combined with the excess supply, had led to the creation of the Fiend Folio. Turnbull went through over 1000 submissions before settling on the final selection of creatures. Some of the monsters only required minor adjustments, while others required significant additional development.[1]

Creatures from the Fiend Folio that had previously appeared in White Dwarf magazine included:

  • White Dwarf #2 ("New Monsters: For Use in Wilderness Campaigns", by Ian Livingstone): dune stalker, blood hawk.[3]
  • White Dwarf #6 ("The Fiend Factory"): bonesnapper, disenchanter, mite, needleman, nilbog, throat leech.[4] Also appearing was "the Fiend", a precursor of the forlarren.[5]
  • White Dwarf #7 ("The Fiend Factory"): eye killer, necrophidius, volt, witherweed.[6] Also appearing were the "gluey", a precursor to the adherer,[2] and the "living wall", a precursor to the stunjelly.[7]
  • White Dwarf #8 ("The Fiend Factory"): carbuncle, coffer corpse, tween.[8] Also appearing were the "chaoticus symbioticus", a precursor to the symbiotic jelly,[9] and the "whirler", a precursor to the vortex.[10]
  • White Dwarf #9 ("The Fiend Factory"): imorph, umpleby, urchin.[11] Also appearing were the "dokon", a precursor to the dakon;[12] the "svarf", a precursor to the xvart;[13] and the "whipper", a precursor to the whipweed.[14]
  • White Dwarf #10 ("The Fiend Factory"): sandman.[15] Also appearing were the "familiar", a precursor to the guardian familiar,[16] and the "warlock cat", a precursor to the hellcat.[17]
  • White Dwarf #11 ("The Fiend Factory"): berbalang, devil dog, sheet phantom (and sheet ghoul), witherstench.[18] Also appearing was the "lauren", a precursor to the tirapheg.[19]
  • White Dwarf #12 ("The Fiend Factory"): assassin bug, grell, hook horror, githyanki, giant bloodworm.[20]
  • White Dwarf #13 ("The Fiend Factory"): doombat, shadow demon, terithran. Also appearing were "fire imps", "smoke imps", "steam imps", and "molten imps", precursors to the fire mephit, smoke mephit, steam mephit, and lava mephit.[21]

In addition to the U.S. and the U.K., contributions came from Australia, Canada, and the rest of Europe. The book also included monsters from the U.S. branch of TSR,[1] some of which had previously appeared in AD&D adventures. These included the drow, from G3 Hall of the Fire Giant King (1978); the jermlaine, from Descent into the Depths of the Earth (D1){{UnknownBook}}; the kuo-toa and the svirfneblin, from D2 Shrine of the Kuo-Toa (1978); the mezzodaemon and the nycadaemon, from D3 Vault of the Drow (1978); the kelpie, from S2 White Plume Mountain (1979), and Lolth, from Q1 Queen of the Demonweb Pits (1980).

The cover art for the Fiend Folio was by Emmanuel, while the interior illustrations were provided by Chris Baker, Jeff Dee, Emmanuel, Albie Fiore, Alan Hunter, Russ Nicholson, Erol Otus, Jim Roslof, David C. Sutherland III, Bill Willingham, Polly Wilson, and Tony Yates.[23] Some of the illustrations for the work had previously appeared in White Dwarf #12 (Apr/May 1979).[20]

In his foreword, Turnbull acknowledged the assistance of Lawrence Schick and Gary Gygax in producing the Fiend Folio; Albie Fiore was also credited as a major contributor.[1]


Turnbull's foreword was dated to August 1979,[1] but publication of the book was delayed for nearly two years.[24] The delays were due to legal disagreements between TSR and Games Workshop.[2] Games Workshop originally planned to publish the Fiend Folio themselves, as an official, TSR-recognized AD&D sourcebook; this was announced in White Dwarf #12, along with hopes to release the book in late 1979.[20] However, after a failed attempt by TSR to merge with Games Workshop by late 1979, TSR established TSR UK in 1980. TSR claimed in Dragon #37 (May 1980) that they'd come to an agreement with Games Workshop to publish the Fiend Folio later in 1980, but the book wasn't actually published by TSR for another year, with a release in July 1981.[2]

Fiend Folio (1e) was released by TSR in July 1981 for $[missing data] US or $[missing data] Canadian.

On January 22, 2013, it was re-released in digital format. It is currently available on DriveThruRPG and Dungeon Masters Guild for $5.99.

Reception and influence[]

Critical reception[]

Many D&D players considered the release of the Fiend Folio a "huge event", as it was the first major introduction of new monsters to the game after the original Monster Manual.[25]

Notable early responses to the Fiend Folio were not favorable. Ed Greenwood was critical of the work in his review in Dragon #55 (Nov 1981), noting its inconsistencies with AD&D rules[2] and many other disappointing elements, although he did compliment a few creatures such as the Elemental Princes of Evil, pĕnanggalan, and slaad.[26] Don Turnbull defended the Fiend Folio against some of Greenwood's criticisms in the same issue.[27] The book also gained a reputation in the 1980s for its "silly monsters", such as the flumph;[2] this "goofy" element was emphasized in Lawrence Schick's review in his Heroic Worlds (1991).[28] In retrospect, some fans suggested the Fiend Folio contrasted too much with the Monster Manual.[29][30]

However, not all reviews at the time were negative. Jamie Thomson gave the Fiend Folio an 8 out of 10 in his review in White Dwarf #28 (Dec 1981/Jan 1982), suggesting it was superior to the Monster Manual in its presentation, as well as noting its Britishness.[31]

In more recent years, the book has been recognized for its historical importance to D&D,[32] including significant contributions such as the githyanki, githzerai, slaad, and death knight.[2] Certain fans have cited the Fiend Folio's unusual elements as a positive,[33] and some who once rejected the Fiend Folio have come to appreciate it for those elements.[30]

As of 2023, Fiend Folio (1e) reached the rank of Mithral seller on DriveThruRPG.

Influence on other works[]

The Fiend Folio marked the beginning of yearly sourcebooks for AD&D.[2]

Jesse Decker and David Noonan, in their 2005 article Monsters with Traction, speculated that the full-color illustration of a githyanki on the Fiend Folio's front cover helped popularize the creature.[25]

The title "Fiend Folio" was reused for the Advanced Dungeons & Dragons 2nd edition accessory MC14 Monstrous Compendium: Fiend Folio Appendix (1992), which updated many monsters from the original book, as well as for the Fiend Folio (3e) (2003) for Dungeons & Dragons 3rd edition. The Dungeons & Dragons 5th edition digital supplement Mordenkainen's Fiendish Folio Volume 1 (2019), which bore the subtitle "Monsters Malevolent and Benign", also updated several of the original Fiend Folio's monsters.

Influence on third-party works[]

The d20 System supplement Tome of Horrors (2002), from Necromancer Games, featured the subtitle "A Folio of Fiends Malevolent and Benign". The sourcebook, with Wizards of the Coast approval,[34] converted Dungeons & Dragons creatures from older editions to Dungeons & Dragons 3rd edition rules, including creatures from the original Fiend Folio. This in turn made many Fiend Folio creatures available under the Open Game License, allowing them to appear in other unofficial works. One such work is the Pathfinder role-playing game, which included them in supplements like Misfit Monsters Redeemed (2010).

Expeditious Retreat Press released the monster sourcebook Malevolent and Benign, with versions compatible with 1st edition (2009) and the Pathfinder role-playing game (2011). Expeditious Retreat also released a sequel, Malevolent & Benign II (2018), compatible with 1st edition.

The Friend Folio (2019) and The Friend Folio II (2019), Dungeon Masters Guild supplements featuring sample sidekicks, also echo the title "Fiend Folio".[35]

The upcoming The Basic Bestiary: Monsters from the Other Side, for the retroclone Labyrinth Lord, is explicitly a homage to the Fiend Folio.[36]
