My question is kind of academic, but I figured I'd post it anyway. Also I am currently Away From Book (AFB).
If I am reading it correctly, the leftside Control ability allows you to invest your Force Die (FD) to 1/round upgrade to difficulty of the next attack/check against you by one
Upgrade and strength allow the ability to be used 2/round with 2 upgrades.
I am assuming that this is a per FD benefit, meaning that if the second Control ability is purchased and your second FD invested, then 4/round you can upgrade the difficulty of an incoming attack/check (I'm not sure on the check part, I think it's just for attacks) twice.
I also realize this is a base xp investment of 20 (specialization) + 100 (talent tree for Force Rating 2) + 50 (Force Power Sense) = 170 xp, which is a significant investment for anyone, and assumes that you do not increase any of your starting skills.
Still it's a nice package.
