Neat, oys about time that this power has a write up. Though isn't this just an application of telekinesis? And since you mentioned this in the description, how hard would it be to containe an explosion?
My though damage+10 with it needing to be maintained each round. Or the difficulty increasing by +5 each round needing a new roll indicating the explosion is trying to expand.

Thanks for the write up!

Well with an RPG, if you can justify something then you can do it if the GM agrees, so yes, Telekinesis could have the same effect if you wanted. Wookieepedia listed this as a seperate power, so who am I to argue with their research, they put far more effort into it than me.

My preference would be for a roll each round to maintain, rather than it just being one roll. To show the struggle the Jedi has to hold back the explosion or energy blast. I wouldn't increase the difficulty each round (there's a chance of a fumble on the wild die, so it would remain a struggle).
Target number, as always GM's discretion, but the Damage rolled might be a good target number, (or might actually be a little high if you're stopping something like the Explosion Kanan held back (but then again he was probably burning Force Points and Character Points at the end)).

Indeed, if the rule of cool applies an attempt can certainly be allowed. Some of my players are into the game mechanics a bit so my thinking has had to change.

I could see the maintain roll working as well. Dice can vary wildly after all. I've seen 15 on 10d6 before.
With Kanan he did look like he was struggling.
Thanks for the response.
