Key

? means that it is undefined in that system.
Att means Attribute, intended to reflect stable abilities that affect many skills, such as strength and intelligence. In dice pool systems, the Attribute is often added to the skill rating to come up with the pool.
CombinedRoll is the total pool, a sum of the attribute and the skill rating, used in dice pool mechanics.
