📖 Overview
Blackmoor is a 1975 supplementary rulebook for the original Dungeons & Dragons role-playing game, written by Dave Arneson with a foreword by Gary Gygax. This second supplement to the D&D rules introduces new gameplay mechanics, character classes, and the first published role-playing adventure, "The Temple of the Frog."
The book expands the game's scope with rules for underwater adventures and a detailed hit location system that assigns hit points to specific body parts. Two significant character classes are introduced: the assassin, a thief sub-class, and the monk, a hybrid class combining elements of fighter and thief abilities.
Notably, while the book shares its name with Arneson's original campaign world, it contains minimal information about the Blackmoor setting itself. The supplement instead focuses on expanding gameplay mechanics, adding new monsters and treasures, and providing additional rules for combat and character development.
The historical significance of Blackmoor lies in its role in establishing core elements of fantasy role-playing game design and its pioneering status as the first publication to include a pre-written adventure module.

🤔 Interesting facts
🎲 Dave Arneson co-created Dungeons & Dragons with Gary Gygax, developing many core concepts from his original Blackmoor campaign in Minnesota during the early 1970s.
🐸 "The Temple of the Frog" was revolutionary not just as the first published RPG module, but also for mixing science fiction elements with fantasy, featuring a high-tech base hidden within a medieval temple.
🎯 The hit location system introduced in Blackmoor was so detailed it tracked 12 different body parts, influencing combat mechanics in later games like RuneQuest and GURPS.
🥋 The Monk class presented in Blackmoor was largely inspired by the 1970s kung fu movie craze, particularly the TV series "Kung Fu" starring David Carradine.
