Every skill has a percentage chance of success, from 0 to 99. To attempt something uncertain, roll a d100 (percentile dice): rolling equal to or under the skill value succeeds, rolling over it fails. A roll of 01-05 is typically a Critical Success (an exceptional result); a roll of 96-100 (or a fumble range set by the Keeper) is a Fumble (a costly failure). Results are further graded into Regular, Hard (roll under half the skill), and Extreme (roll under a fifth of the skill) success — the Keeper calls for the appropriate difficulty based on the situation.
