I probably should have posted this months ago but I thought it was pretty obvious, I am surprised by the amount of people meaning everyone I know that still hasnt figured this out so here.
Basically you just get as close to one of the pillars as you can and just stand there, dont move, use any dmg reduction cd's you have and then after about 5 seconds it will stop hitting you and you can continue just standing there doing nothing until the quest is complete. I will post a vid in about 10-20min.
