Pull adds away from the named...cooperative effects
Traumatic Swipe to break the timing unity for the Trauma AoE and Vortex
Raid members must be within 17m of Named/Adds as much as possible.
Trauma based AoE - Runic Vortex. Happens roughly the same time the adds pop (every 45s).
Adds will spawn that need to be killed. They will pop the top of the room entrance ramp, or bottom of the room exit ramp.
Curse called Cleanse that Must be cured or it will spread and wipe the raid.
tl;dr - Cure curses. Survive AoE, kill adds, kill named.
