After a while of playing, I was unsatisfied with how the force powers were used. Throughout the books, and possibly even the movies depending on how you interpret them, you see characters use force powers which they never trained. In my game I am considering an optional rule to allow force users to overextend their force use, allowing powers they may not have.
It goes as follows:
Cost: 1 Destiny Point and 2 Strain - Force user may be treated as having a basic Force Power (such as Move or Heal/Harm, etc), which they do not have. Alternately, they may be treated as having one upgrade (Control, Magnitude, etc) which they do not have, but have all prerequisites for. This only lasts for 1 round, regardless of whether the activation works or not.
Cost: 3 Destiny Points and 6 Strain - As above, except may have base power + 1 upgrade or 2 upgrades.
Cost: 6 Destiny Points and 12 Strain - As above, except may have base power + 2 upgrades or 3 upgrades.
We thought the advancing cost makes it very expensive, but if you just can't survive without the stretch, you can overload yourself to do something amazing.
I would love to hear your thoughts.
