Paradox Inversion Core presents a generic, universal system intended to support gaming in any genre or style. Characters are built from Attributes and Skills. Additionally, character Archetypes are used, and characters can gain experience and improve. The game uses a larger number of Attributes: Strength, Dexterity, Agility, Intelligence, Charisma, Alertness, Spirit, Endurance, and Offense. Characters also have a number of Derived Attributes, primarily dealing with combat ability. Attributes have numeric values ranging from zero to five, averaging two. An Attribute score reduced to zero typically has significant penalties.
