Now I got a scenario the might be an interesting twist...

Player one shoots at player two with the goal of player 2 redirecting the shot around the corner at targets they cannot see...How would you do that?

Well, I mean, Player 2 technically has to be able to see, or it's just pure luck at that point...

Maybe a ranged shot by Player 1, and they need 3 Advantage/1 Triumph for each shot they fire, and Player 2 needs to spend the Strain, but doesn't take any of the damage? Difficulty upgraded once, maybe twice, since Player 1 is obviously firing at a fellow player. I would say Player 2 doesn't need to worry about damage from the attack since in this case, Player 2 is anticipating the attack and Player 1 is probably aiming directly for where Player 2 has their lightsaber(s). Unless a Despair/ton of Threat gets rolled that is.

It sort of seems possibly broken, but I figure that the 3 Advantage/1 Triumph that could be instead spent on criticals, and the generally harder difficulty that might directly lead to injuring Player 2 who also has to burn Strain to do this, sort of balances it. But I guess you could also require a Destiny Point if you feel it needs more.

Perhaps an upgrade of difficulty to give an "Accident" a chance of happening, flip a destiny to do it? Require 3 Advantage or a Triumph to trigger the hit on the actual intended target, Both players suffer strain to activate the ability.

Edit: I think it should be a cinematic moment as well; the BBEG is about to escape and no one else can stop them.

Doing that on purpose actually sounds kind of cool, in the style of that brief moment in the first Avengers movie where you see Iron Man angling a repulsor blast off Cap's shield to take out a foe.

I think my interpretation of this kind of situation would be that, if a GM is willing to spend a despair on a ranged attack to change the target to a character that has the reflect abilities, the character that has every right to use those abilities as if he were the target of the attack.

Because he's now the target of the attack.
