User summary: Characters in Stellar Sanctums have eight Basic Stats (Strength, Agility, Health, Intelligence, Will, Virtue, Vice, and Perception), generally rated from -5 to +5. The rules suggest using D100 and trying to "roll under" the appropriate Basic Stat (which makes no sense, but that's the rule--see image). Opposed rolls (e.g., personal combat) work similarly. A Task Result Table is used to determine outcome based on the roll and the action type. The rules also present a separate method for handling "Vehicle" (smallish) and "Ship" (largish) movement and combat. These rules are not similar to the character rules, but generally do use percentile rolls. Mecha are handled under the "Vehicle" rules.
