Core Mechanic
Roll d20 + ability modifier vs. DC/AC. Real-time torch tracking (1 real-world hour per torch), risky spellcasting (fail a check and lose the spell for the day), and randomized character generation (3d6 down the line).
Best For
Tense, fast-paced dungeon crawling where resource management and player ingenuity matter more than character builds. Ideal for groups wanting old-school lethality with a modern, 5e-familiar ruleset.
Highlights
Real-time torch mechanic adds tension, near-zero prep with built-in random tables, 5e-familiar so easy to learn, fast combat
Considerations
Limited character customization at creation, random talent progression removes some player agency, real-time torch tracking requires consistent timekeeping, carousing is the only XP path
