Editing Cortex System (section)

== Mechanics ==
The system uses d2, [[d4]], [[d6]], [[d8]], ... you know the drill. Each of a character's attributes and skills is assigned one of these die 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 "[[dice stepping|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.
