Strength--> Lift/Carry, damage bonus/penalty, every point is a multiplier for maximum TK lift/Carry capacity.
Agility--> Dodge bonus/penalty, skills like balance, tumbling, etc, general flexibility and movement modifier, sometime Reflex save modifier
Dexterity--> attack bonus/penalty, parry bonus/penalty, pick locks, prestidigitation, speed-
based iterative attacks, etc, sometime Reflex save modifier
Body--> hit-point modifier, personal, unarmored damage resistance (minimal at best and requires a Fort save, so don't freak out) Fort save modifier for poisons, disease
Endurance--> skills like running, how much pain can the character take? how long can he hold his breath? Morale for NPCs, duration for things like Barbarian Rage, duration for maintained spells or psionics
Mind--> mental alertness, more or less (modify at will).
Perception--> listen, spot, all senses, really, modified by this one, also modifies spellcraft checks, certain artistic skills, such as musical performances, painting and the like, appraise skill, general detection, psionic mental-power modifier
Presence--> this is how much and how you are noticed by those around you. "As he stepped into the barroom, his shadow snuffed out conversations, like a wet blanket on a merry blaze." A lawful evil person with a high presence.
Influence--> this is exactly what it sounds like, and provides a modifier to things like intimidation or other forms of persuasion, gather info, leadership, morale boosts from NPC leaders for their henchies, a basic indicator of what people are willing to do for you if you ask them.
Appearance--> sheer good looks or cussed-ugliness. (modify as needed)
Sorry, but I couldn't pick just one. The ones in here that are part of the abilities list as it stands have been modified enough that I thought they deserved to be at least mentioned.
Thanks,
Steve
