Besides skill points, does int have effect on force powers?

Wisdom is the biggy for determining force powers?

Charisma determines what in force powers? What is a good number to start with.

To my knowledge, INT only affects skill points. Wisdom is indeed the biggy for Force powers, as it determines how many Force points you have, and thus how often you can use your powers. I believe for some Force powers charisma gives a bonus to the affect (like to hit, or whatever).

wisdom and charisma bonus both add to the number that enemies have to roll over in order to save against any offensive powers you have.

wisdom determines number of force points.

charisma probably plays more of a role in affect/dominate mind than wisdom (if wisdom plays any at all).

intelligence adds nothing to force powers.

The charisma multiplier is applied to total force points as well...
