Megadestroyer never appears
He’s actually there, just under the surface, if you guys would have used enough of your AOE skills to get him to 25% health, his phase 2 would have started. But yeah, still a bug.
I’ve never seen this happened for the past 2 years. The question is how/why Megadestroyer spawned under the lava? Was there something in the way that causes him to spawn under the lava?
As a ranger, I tried to AOE the bright spot in the lava (on the assumption that corresponded to MD’s location), to no visible effect: no damage floating text appeared, and of course there was no health bar visible and no way to target a submerged adversary explicitly.
It is always possible I simply missed, but I am not certain AOE would have been effective.
