I know this is super old content, but I've been suddenly getting this trial a lot lately in roulettes for some reason. I'm terrible at remembering fights in old content, so usually I just wing it and everything turns out okay.

During the final phase of the fight, a random player gets a stack marker. Pretty straightforward. Everyone rushes in to stack on the player. But you're supposed to stay stacked for a few seconds after the initial burst because Nidhogg unleashes like three or four more blasts.

I notice sometimes after you're done stacking, he turns to individual players and one-shots them. There is no telegraph, no visual warning of any kind. He just randomly turns and decimates half the raid. That's not an exaggeration. That actually happened the other night where he turned and killed the healer and two DPS, one of them being me.

I cannot remember for the life of me how I always avoided this in the past? Videos don't say anything about it. I doubt it's a new mechanic. The only thing I can think of is that maybe we didn't stay stacked long enough? Or maybe the tanks were running it for the first time and losing aggro?

This has happened twice now and it's kind of embarrassing that I'm dying in this fight. Clearing Eden no problem. Killing Nidhogg? Huge, massive, problem.
