Akh Morn
This attack is very deadly here! Each cast will spawn two pillars of death, one heavy damage version on the main tank (which targets #1 on enmity list each pulse), and another one on a random DPS (which stays in place).
To deal with this, tanks need to hug each other to share damage of their Akh Morn or use their ultimate mitigation (Hallowed Ground, Holmgang, or Living Dead) to solo these. While DPS make sure to not stay in the second one for too long. The tanks usually decide pre-pull how they will handle these.

If a tank fails these they will die very quickly, then the main Akh Morn targets next player on aggro list and will kill the party one by one very quickly.
