Blackmoor, the second supplement to the original Dungeons & Dragons rules, is known for its introduction of rules for underwater adventures and hit location, and the addition of the monk and assassincharacter classes. Dave Arneson named the booklet after his original role-playing campaign world, Blackmoor. It has additional rules, monsters, treasures, and the first role-playing gameadventure ever published, The Temple of the Frog. Despite the name, the supplement included almost no information on Arneson's version of the world. Blackmoor added two new character classes to the game: the assassin, a sub-class of the thief; and the monk, a "monastic martial arts" sub-class of the cleric, intended to be a hybrid of the fighter and thief classes. The Sage character was also introduced, but changed to a Non-Player Character type and moved to the back of the booklet by the editor. The book also introduced a section on diseases and a hit location system, wherein each individual body part of a character or monster was assigned its own hit points. The odds of hitting any specific body part changed depending on the character's height and weapon reach. If any individual body part was brought down to zero hit points, the creature would be crippled or killed. The supplement introduced rules for underwater adventures, such as rules and guidelines for swimming, equipment weight restrictions when fighting underwater, and the effects of underwater combat on weapons and spells. Blackmoor also includes numerous new water-dwelling monsters and equipment useful for underwater adventures. A number of these underwater monsters and magic items were the creations of Steve Marsh, added to the supplement in order to compensate for material by Arneson left out of the final edit.
Publication history
Following the release of the original Dungeons & Dragons rulebooks, Gary Gygax and Dave Arneson decided to publish expansions of their respective campaigns. For Arneson, this expansion would be based on his Blackmoor campaign, which had originated in the first quarter of 1971. In March 1975, Gygax told a wargaming newsletter that Arneson was working on a final draft, and TSR began accepting preorders for the product and advertised it in The Strategic Review. The booklet was delivered late, in part by having gone through two editors and being temporarily misplaced. The final edit was done hastily in a few weeks. The Blackmoor expansion was published by TSR, Inc. in 1975 as a sixty-page, digest-sized book. It was the second supplement to the original Dungeons & Dragonsboxed set and bears the designation "Supplement II," with Gygax's Greyhawk preceding it in the same year. The book features illustrations by David C. Sutherland III, Mike Bell, and Tracy Lesch. The supplement was edited by Tim Kask, who also did development on it. The Temple of the Frog was later revised, expanded, and released as DA2 Temple of the Frog. The Blackmoor supplement was reproduced as a premium reprint on November 19, 2013, as part of a deluxe, premium reprint of the original "White Box" which features new packaging in an oaken box. The reprint includes: Volume 1: Men & Magic, Volume 2: Monsters & Treasure, and Volume 3: Underworld & Wilderness Adventuresplus four supplements: Supplement I: Greyhawk, Supplement II: Blackmoor, Supplement III: Eldritch Wizardry, and Supplement IV: Gods, Demi-Gods & Heroes. Each booklet features new cover art but is otherwise a faithful reproduction of the original, including original interior art.
Reception
Scott Caspar writing for website rpg.net says: "Blackmoor was the original campaign and this was its first published supplement. It holds up poorly to examination today, but it is still a worthwhile endeavor for anyone interested in the history of gaming or "Old School" gaming." He gives it 2 stars out of five
