The Cortex System is based on the Sovereign Stone System. The system described here is the one detailed in the Serenity core rule book. Margaret Weis Productions, Ltd refined and expanded the system for their Battlestar Galactica role-playing game. The system uses dice with 2, 4, 6, 8, 10, and 12 sides, described with the standard role-playing game notation of d2, d4, d6, d8, and so on. Each of a character's attributes and skills is assigned one of these dice types, with larger dice representing greater ability. So, for example, a character might have Strength d6, Intelligence d8, Athletics d4, Guns d10, and so on. When a character attempts an action, such as piloting a spacecraft, shooting a gun, or punching someone, the player rolls the die for the character's applicable attribute and the die for his/her appropriate skill, adds the results together, and compares the total against a difficulty number. Tasks of greater or lesser difficulty are represented either by increasing or decreasing the difficulty number or increasing or decreasing the dice the player rolls by "steps," with each step raising or lowering the die type by one. So a d10 with a two step penalty becomes a d6, a d12 with a one step penalty becomes a d10, and so on.
