Game system used by The Caverns of None Shall Pass, a gmaebook written by Andi Hagen.
The system uses a single six-sided die for tests. A character is created by selecting one of five races, dividing 12 points among 5 skills, and a "stamina" attribute of 2. Players also get to choose from a list of items prior to beginning the game.
During play the players can gain additional skill points.
Tests are made by rolling a six-sided and comparing it to a skill rating.
