I've plumbed the depths of these forums for answers to these very questions. Here's the best I've got.

1. I'm certain it's just the one Discipline roll.

2. Adversary would affect it. After much discussion on another thread, I've decided that it would NOT be opposed. The sidebar you reference says that it is opposed unless "it is already a combat check" which this is. Dodge, Sidestep, Adversary, even cover would apply. Per RAW reflect would NOT apply, but a lot of GMs on these forums allow it at there tables.. that's a judgement call.

3. I had not noticed the rules didn't specify whether successes add damage. It's a ranged combat check, and every other ranged check has successes adding to damage.. so I would likely run it as such.. curious what others on these forums have to say on this one though.

4. Didn't quite understand you on this one. I will just break it down, as best my sleep addled brain can. Basic Power 2 force pips to activate. If you have one rank of Range, 2 more force pips to increase your distance to Medium, for a total of 4 pips spent. If you wanted to go to Long range, spend another 2 for a total of 6 pips spent.

If you had 2 ranks of Range instead of one: Activating your range talent with the 2 pips, activates all of the range talents you have purchased. IE: you spend only 4 pips (2 for the basic power and 2 for the ranged talent) and you go to Long.

Same holds true for Strength upgrades. If you have one strength upgrade and you spend one pip +1 dam. Spend 3 pips +3 dam. If you have all 4 strength upgrades: spend 1 pip +4 dam, spend 3 pips +12.

5. Yes soak is applied.

Hope that helps

Q1 Answer) It's just the Discipline check, with the established difficulty of two purple supplanting the normal process for determining the base difficulty of a ranged attack.

Q2 Answer) Adversary would upgrade the base difficulty of the Discipline check, same as any points of Ranged Defense the target might have adding setback dice to the difficulty. The line "ranged attack" is an indicator that anything that would defend the target versus getting hit with a blaster or thrown object works to avoid getting hit with Unleash.

Q3 Answer) That is correct, in that each uncancelled success adds to the damage, the same as it does with any combat check.

Q4 Answer) Yes. Thus, it behooves you to purchase more Range Upgrades if you're looking to routinely blast targets from further away.

Q5) Yes. Note that Harm specifically says that it ignores soak, while Unleash doesn't have that verbiage. Reason being that using Harm doesn't require a combat check; unless the target can defend against Force powers, they simply suffer damage. And without a combat check, there's no inherent way to boost the damage apart from Strength Upgrades. For Unleash, since it is a combat check, it has a built-in method to up the damage using a skill that many PCs are going to have sunk a fair amount of points into, thus soak gets applied to keep Unleash from becoming an instant one-hit KO attack.

For question about the range, it is just ones the cost of range.... the Range said spend 2 to increase range EQUAL to RANGE UPGRADES PURCHASED

So if you got range 2 (long) it is equal 2 not 2 times the cost.

it will be 2 points to encrease to long range , not 4.

yes with 2 range upgrades it costs 1 pip to increase range twice, and 2 pips increase range 4, with 4 range upgrades it would cost 1 pip for 4 range increases.
