Let's just say that I'm a little stoked that we did it. Kudos to the other 6 for sticking in it and managing resurrections, and especially to the Wa/Mo who brought Healing Hands, which prevented a few deaths by buying my time to recharge skills. For those of you who're wondering, here's the build I was fiddling with when we went in (screened just after finishing):
Weapon: Kepkhet's Refuge (only one I used during the mission)
DF: 12+3
Protection: 12+4
Smiting: 3+1
Yes, I'll be sure to tell the monk we made it.
Go figure, you don't really need three (or even two) monks for some missions after all.
Just a little teamwork and a skilled set of players.

, so I must heal for 7 ppl but we still decided to continue and finished missions (Healing Seed ftw). The important thing is your teamwork and no one rushs.
