Hello, thank you all for taking the time to answering this question. I've attempted to look for an answer, and could not, so I apologize if this has been addressed.

I am currently in an Age of Rebellion game, where my character is an Ace Pilot. I am considering making him Force Sensitive. The talent tree is self explanatory. What I am having an issue wrapping my brainfruit around is the Force Powers themselves.

To this issue, I will be referencing the Enhance Power line (It is the one that interests me the most for my character).

I understand the mechanic in rolling Force Die x Force Rating when activating the basic power, the problem is understanding the Control/Range portion.

Looking at the first "Tree", you have 4 control ranks: One allows you to use the base ability on Coordination Checks, two allows you to use both piloting, and the last gives you an agility boost with committing a force die.

Question is thus: Do each of these Skill Control checks require their own Force Point to activate, or by unlocking the ones further down allow you to use them all?

Example being: If I have gone down the entire tree to unlock the agility boost, would I need one force point to get ALL of the boost to skill checks, or would I need one for each skill individual check?

The basic Enhance power applies to Athletics checks. Traveling down the tree, you are able to make it apply to Coordination, or Resilience, or Brawl... in all of those instances, it's going to behave the same as the basic power does, only for the specific skill checks. Essentially you've purchased Enhance Athletics, and then you purchase Enhance Coordination, and then Enhance Resilience, so on and so on. Each being a different application of the Enhance power.

In each case, you roll your normal check but you add your Force rating worth of Force dice to the roll. So say you're making an Enhanced Pilot (Space) check. You've got Agility 4 and Pilot (Space) 3 with a Force rating of 2. You're going to roll YYYGFF (that's 3 yellow Proficiency, 1 green Ability, and 2 Force dice). The regular dice resolve themselves normally, but you can spend any Force points rolled to give yourself extra Success or Advantage toward the overall Pilot check.

In regards to the two Ongoing Effects towards the bottom of the tree, they each say you have to Commit a Force die in order to activate and maintain the effect. Rather than a quick and sudden burst of Force, this is a focused and concentrated effort. So where you normally have Force rating 2, you can take 1 of those dice away in order to keep the Brawl or Agility effect running. Going back to the previous example, now your Agility is effectively 5, but you only have 1 Force die to roll with (the other is busy keeping the Agility boost active). You could commit both of your Force dice, giving you +2 Agility, but you wouldn't have any to roll for the Pilot check. Instead, you'd be rolling Agility 6 + Pilot 3.

In general, when a different power further down the tree requires extra Force points spent, they will say so. Specifically for Enhance, each tier down the tree is saying you get to use the basic power exactly as written, for a different skill.

Ah perfect, thank you so much for the information, that clears up EVERYTHING!

Now in regards to a more complicated Force power, such as the Move power on AoR pg 296...

The basic power requires you to spend 1 Force point to move a Silhouette 0 object around within Short range. You always have to spend this first point, regardless of what upgrades you may be using as well.

Once you start purchasing Magnitude, you can spend +1 Force point to affect (Magnitude) worth of extra creatures. If you had 1 rank, every +1 Force point you spend gives you an extra target. By the time you have 4 ranks, every +1 Force point you spend gives you an extra 4 targets. You could spend 1 to activate, and 1 more towards Magnitude, and start moving 5 targets around at once.

Same goes for Strength and Range. Since each one says "equal to upgrades purchased" that means each extra Force point spent will do Rank worth of stuff to the overall effect. Rank 1 Strength gives +1 Silhouette for every +1 Force point. Rank 4 Strength gives +4 Silhouette for every +1 Force point.

So like I said, the books will tell you where extra points have to be spent, and what spending them in different ways will do to the overall effect. You just have to read carefully. =)
