I had set it to anything weaker than 100 damage
so Heavy Plasma, Sniper Plasma, Cyberdisk, stuff like that up into the hundreds is unaffected. That bigger flash is an important exclamation point.
but plasma rifle, reticulan plas, tri-shot, plasma sub, elite pistol - I figured for the overall power being inflicted its enough of a warning to see the green plasma projectile.
I actually would have wanted to make it a tiny bit larger but my art skills are crippled right now, I had to be sure it would stay lined up.
