Quick rules summary
Roll d100 against your skill value (plus any Advantage bonus). Success Levels are calculated as the tens digit of your skill minus the tens digit of your roll. A roll of 01-05 always succeeds and 96-00 always fails, regardless of skill. Doubles at or under your skill are a critical success, and doubles over it are a fumble.
