Cyclops beam devastation

[Lord soth]

Does Cyclops optic devastation get to do concussive force with each swirl or is it only once? 

[Negoldar]

Only once. 

[RJ1040]

Let's say Optic Devastation is used against 2 targets. In the first attack roll against target A there is a Wild, and in the 2nd attack roll against Target B there is not a Wild. Which targets will suffer the effects of Concussive Force?

[Negoldar]

Target A will get it. Target B will not.
