Fourthcore Alphabet
A reference for Game Masters creating dark, deadly dungeons in the fourthcore style. Each chapter examines a key element of fourthcore design, explains its role in the genre, and provides a d20 table for generating numerous examples. The material is written with 4th Edition rules in mind but can be adapted to other fantasy roleplaying systems, including games focused on gothic deathtraps and challenging dungeon exploration.
