Yggdrasil here, looks like 2 ghosts, attacked them, died in about 2 sec as a tank with 13k hp because the 2 became about 10 each.
This is also happening on EU Central Alfheim. About 20 or so enemies stacked on top of each other
Same happening in EU Central Heracleion, unplayable.

Since bugged on Rauch. How is this not on the Known Issue list? Apparently you will need this for the void gauntlet quest so you better patch this when it comes out
Still bugged. Piles of ghost here, which insta-kill you.
