User summary: Characters in Demon's Lair are defined by Class (using a dual class system) and Race. The game's magic system is based on a magic "point" pool. Combat uses a three-die mechanic (attacking/defending/special) featuring a modified die-vs-die resolution system (attacker's attack die vs defenders defend die). The die type used in each role is determined by the character's core class. Demon's Lair is set in Terrania, a world containing several major continents, each containing several major political divisions. The game consists of two rulebooks, three supplements, and - to date - four published scenarios.
