Huh, that's probably tallying overkill damage as well, seeing as the precision shot only can only effect one enemy while the explosion can be applied to other enemies. But I'll test it in a short while on an enemy that won't die from one hit.

Ok try, but you give 5xx aoe damage

So It's weird. It only doubles the damage on Vex. Makes sense actually, but not in terms of game design xD. I'm going to make a thread with the clips I made, it'll be ready in a second. So I owe you an apology, because while it does in fact increase your overall dps to the Vex, it does not to the Hive at least. So it is inconsistent but you are also not wrong :-)

No problem man, the fallen also take that dps, but sometimes the firefly perk doesnt work.
