I recently finished B gloves on my 15 pray zerker. DT and MM are by far the worst quests to do. I died once during DT.
Blood diamond/Dessous: Used a Trident of the swamp. Easy kill.
Ice diamond/Kamil: Used Fire blast and had someone block the wolves part for me. Fight was real close.
Smoke diamond/Fareed: Used the highest level Water spell I could use with Ice gloves equipped. Died once, didn't think this guy could hit 35s, otherwise I would have eaten up. Beat him second time around, but it was a close fight.
Shadow diamond/Damis: Trident of the swamp. For some reason I could not get the safe spot to work against this guy. My character would just walk away from the torch and then Damis would deal so much damage. I ran out of food, but luckily I had venomed the guy so I just waited for it to kill him while I was hiding behind a wall, then I looted the diamond and tele'd away.
