Right now there are 3 possibilities that can occur when Dwayna turns invisible at 50%.
1) 5 sparks spawn and you can kite them back to the center for the boss to reappear.
2) 1 spark spawns and you can instantly get the boss to reappear
3) 6 sparks spawn, and you can do nothing except wait for the boss to regen back to full health before you can try again.
More often than not, the 6 spark possibility appears, whether the boss disappears at 50% or again at 25%. This makes it near impossible for a regular party to defeat the boss, since you’re hoping for the bug not to appear both times (at 50% and at 25%).
The only other way to do this is to out DPS Dwayna’s healing when she turns invisible. Again, this is near impossible unless you have a fully glass cannon/condition damage spec party.
In addition, pets, summons, spirit weapons of any kind will also sometimes lure sparks, and cause the sparks to keep aggro on them until they die or disappear. Something to consider to fix also.
So here are my two cents:
1) Either fix the extra sparks bug (which apparently has been here forever, and still waits to be fixed)
OR
2) If you can’t seem to figure out how to fix the bug, at least temporarily lower Dwayna’s regen rate so that a normal party would be able to outDPS it.
