Intelligence - Ability to integrate and process concrete information into abstract concepts that allow character to predict future outcomes, and produce repeatable solutions. PC does an intelligence check when encountering abstract problems.
There are two types of intelligence, convergent (CI) and divergent, (DI).
Convergent intelligence is the ability to take multiple variables and narrow a problem down to one solution.
Divergent intelligence is the mental ability to take many or multiple variables and integrate them into a larger picture, aka creativity. High DI yields the ability to think outside the box and moreover, to see outside one’s current knowledge.
High CI allows the PC to think within their own host of previously acquired or newly available knowledge to find a solution to given or new problem.
Problems which require both of equal amounts of CI and DI simultaneously are handled by the first, general overall intelligence score.
Wisdom - Ability to understand broader ranging problems that one typically thinks of in terms of having ‘wisdom with age.’ PC rolls a wisdom check for example, when trying to decipher the overarching motives of a person or organization, or what to do when rearing a child.
Strength - Pure physical strength.
Charisma - Ability to enrapture and motivate other characters to do what you wish with a currency of awe (of you or your supposed knowledge or ability), gratitude, flattery, self-esteem (theirs and yours) and the overall ability to make others feel important and excited to be around you. This self-importance is typically something one is unconscious to; tacitly accepts, and yet requires to bolster their own self-esteem. That is why people cling onto charismatic characters, as they lose that self-esteem when separated from the charismatic individual. PC rolls a charisma check upon needing to influence another character to do something they want.
Biological Beauty - The amount of facial and bodily symmetry designated for disease resistance, and selective procreational survival.
Tedium - The ability to put up with boredom.
