scryl, drexer ultimate deathknight miscreated monster armiger

use from forge accuracy sets thats easy way to get alot accuracy

armiger needs  at least 180 accuracy 

kill little spiders if you have nukers

if not place hp burns on them and stun them

By "forge accuracy", you mean Perception, right? Thnx, I'll try that.

try manual runs sometimes auto mess alot

yes  thats very easy to get fast accuracy  

That's the problem, I could beat it on manual runs, but the Dungeon Mission requires 14 wins on Auto.

do you have coldheart maybe

Gearing is your issue. You said it in your op so you must know. Looking at your deliana she has almost no speed. Go farm speed boots. Spider until 17ish you don't even need any specific strat you just aoe nuke down and brute force right through it. You can do this with your elhain, athel, and udk. Why you have two starters maxed is another questionable choice and you seem to be working on a kael as well.

Crit cap your champions and get them over 170 speed. 

One thing that helps on auto - click the boss. It'll make sure everyone targets her instead of weak spiderlings.

No. Wish I did...

Truth be told, THAT is another problem, they ALWAYS target the boss. I could do it easier if I could get Zargala to target a Spiderling with skill #2 but she never does. So unless this trick can be done repeatedly, I can't. 

And targeting only the boss gets the tank killed very quickly with no progress made. 

You can turn the fight off of auto at any point, and as long as you turn it back on without doing anything, you're okay. So if you have zarg coming up soon, you can take a breather, evaluate, turn it back on auto, then target a spiderling so she kills it with her a2.

Realistically speaking though, as much as you hate to hear it, gear is your issue. UDK can tank all the spiderlings forever, so you just need tm control on the boss and healing for udk.

Truthfully, that is the biggest problem, UDK doesn't last long.

In a year or so, you'll pull one Coldheart.  As soon as you do, you will pull 12 more within a few weeks. Lol sorry that's the way it was for me with so many vital champs.  It took me 18 months to get the first, since then I swear I've eaten 50 of them.

Hahaha, yeah, I know what you mean.

Took me about 5 months to pull one of the other starters, now I think I have two of each EXCEPT the one I started with.

Hp/def% gloves and boots, res chest, hp/def ring/amulet, res banner. Get at least 3200 def, 60k hp, and 300 res. Since you don't need any other stats, that should be very doable.

Third time...

I'M ON A BUDGET. I HAVE TO USE WHAT I GET.

I'd love a res banner, but only prayers to the RNG are going to get me one. I can't simply choose from a dozen Banners, seeing as I have at most 2 for each Faction. 

But hey, I have that armor you mentioned... Should take another week of grinding to get enough silver to remove it from the Champions who have it and swap UDK's armor (that I thought would work last time), so I'll let you know then. Sigh....

I dont know what you're hoping for from people. You're asking for a team, I'm giving you one. If you can't reach the stat requirements with items, look for set bonuses or glyphs to help you get there. If that doesn't work? Farm more.

It's just frustrating. Nobody seems able to offer any help other than, "Use things you don't have."

You have the easiest step of the puzzle to solve. Gear is literally the only part that can be farmed. As for the stats specifically, use one of the various optimizers if you need - for UDK here specifically, since literally the only three stats you care about are HP, DEF, and RES, it shouldn't be hard at all to reach. Like I said - set bonuses, glyphs, masteries, etc. All should help you get there.
