Page 280 when it describes force power checks, right before Combined Force Power checks.

A force power is always "successfully" activated, even if the check does not generate any force points to spend on the power.

What does that mean?

Means the power takes up your action no matter what the result is and that something happens regardless of success or failure. Basically you reach into the Force you attempt to do something and even if it fails you still reached into the Force to attempt to do something. Maybe Lukes lightsabre is still stuck in the snow but you see it wiggle and move. Or maybe the X Wing starts to rise from the swamp but it then just falls back in. Something happens, whether or not that something is what you were hoping for depends on if the check generates the pips you need.

thank you, i was very confused with that sentence in the book. i was like, how can something succeed if it failed?
