Khorod said:Force Points in d20 Star Wars, very like Action Points.
Well, yes and no.
When you spend a Force Point in Star Wars, you roll 1 or more d6s, and add that result to all attack rolls, saves, abilty checks, and skill checks (fundamentally, all d20s rolls) until the beginning of your next turn.
Note that this means that one Force Point can, potentially, effect a large number of die rolls (such as, spending the FP at the beginnng of your turn, before you make a large number of attacks).
The number of d6s you roll when you spend a FP is dependent on (a) your character level, (b) whether or not your PC is Force-sensitive, and (b) if you're Force-sensitive, whether you're calling on the Light side or the Dark side.
If you get more than 1d6 on a Force Point, you add all of the d6s you roll together to determine the effect of the Force Point -- this is different from Action Points, where you use the highest result of the multiple dice.
Unlike Action Points, which can be spent to emulate feats, activate class abilities, etc., affecting die rolls is by far the primary use of Force Points. The non-die-roll uses are fairly limited (Jedi have to spend one to build a lightsaber, you can spend a FP to atone for a Dark Side Point, but those are the only ones I can think of off the top of my head).
Also, unlike Action Points, Force Points can be difficult to earn. PCs only start with 1 FP (2 if they're Force-sensitive), you only earn 1 FP each time you gain a level, and the only other way to earn a FP is by making a heroic action "at a dramatically appropriate moment." (OK, there's one other way: when a Jedi builds his own lightsaber, as part of the Knight Trials, he spends 1 FP, but gains 2 FP when the saber is completed, for a net gain of 1 FP.)
Finally, non-Force-sensitive characters can have no more than 5 FP at any one time.
I've seen variation on whether you roll the d6s once, and apply that same result to all your d20 rolls, or roll the d6s separately for each time you roll a d20, and I'm still not positive as to which version is RAW.
