AOE Splash Damage but, only hits other players

I hope I posted this question in the right place. Basically, all I need is how to tell a (spawned actor < spawned from another actor < spawned from the player) not to send variable information to the player that spawned the original projectile.

Thanks in Advance.

Not sure if I understand your question but it looks like you want to use the built in Apply Damage function. It needs the Damaged Actor (target) Event Instigator (The Controller instigating the damage) and the damage causer (in your case the AOE lightning?)

Then on the server check if the Instigator of the Damaged Actor is not the same as the Event Instigator before applying damage.
