Yes, do it on my PM wizzy all the time. Cold absorb t3 weapon, Fire shield fire version, cold resist and I take about 60 damage per aura proc. In undead form with Death aura almost doing all the healing and an occasional NegBurst to top up. I stay just a bit away from the bottom of the stairs, refresh Cloudkill and Incend Cloud and throwing some nukes/dots while at it.   It's so easy it's not even funny .  Done it on elite as well, not much different from normal.

If WF Recon and one additional repair spell would do the trick nicely. If you dont have a t3 cold absorb weapon or alternative absorbtion you can also add Prot from Elements.

If not on self-healer you can ask one of the healers to heal you, p2 usually isn't heal/mana intensive at all.

  Imho, tanking is much easier and safer than kiting, especially if you can self-heal reliably. Once you try tanking you never go back to kiting.
