Berserker Uber problem

[Nattarefrosten]

Hi
I have a lvl 89 berserker and im trying to Uber run with him... and its not
going great :( he kills baal and diablo easy but meph... baba and the merc only dies.. what can i do?

My gear:
helm: Arreats (socked with 15ias 5max)
armor: Enigma / CoH dusk when in Uber
wep: Death CS
shield: Storm (socked with Pdiamond)
belt: Verdungo 11/38
ring: Raven20
ring: Raven19
boots: Gore / once upped Goblin toe when in Uber
amu: Highlords ... what should I use in Uber?
inv: 2 WC charm, Torch 10/12, some life charms and some max/ar charms

Mercs gear:
helm: Kiras (socked with ias)
armor: Duress wyrmhide
wep: eth Bonehew (AmnAmn)

My build:
20 berserk
20 howl
20 shout
20 bo
5 wc
4 sword mastery
1 in conc, faster run, natural resist, battle cry and so on

I have 3500 in life and around +50res after mephs aura.
Can i do any changes with my eq or my tactics to kill meph?
Thanks in advance :D

I think you're ok for crushing blow and I'm assuming you've got life tap on your gloves in which case all you can do is maximise resists and get some lightning absorb when tanking meph. Merc will nearly always die but obedience and socketed guillames will ensure he goes down fighting. :)

Cant leech with Berserk, even with tap, and that weapon must swing mighty slow.
I'd prebuff with Treachery for maxing res and toss on TGods.
If you are using Drac's, I believe you get a bump in OW damage @lvl 90
Or you could try LoH, the 20% ias might help (check tables) + 350% damage to demons.(also +50% fire res can't hurt)

HL ammy is good imo.

Thanks for the replys

I am right now using LoH.. and yes it is a slow wep :)
If I would use treachery i would swing faster but i think i need my CoH for res..
and my dungo for life.. but could try the combo Tgods and treachery..
Would it work if I used Dracs and instead of berserk used Conc? i have 1+items
wich lands my Conc skill at about 13 or something like that... Then I could leech but would get poor AR..
Btw what is important to have high res against? only light or does meph use other elemental dmg?

[Barloc]

Actually with treachery, you just prebuff the fade prior to going into the portal, then toss the CoH back on( nice thought on the IAS tho ). That'll give you a nice res stack and max DR% with your shield, so no need for Dungo's that way (life bonus isn't huge either since it isn't affected by BO on +vita).
My Barb is WW and I use my base conc skill to uber with so I'm sure it'll be no different with you(well, except for your attack speed). I don't consider the AR real bad since it's about the same as my WW at max, plus I would commonly prebuff with demon limb for the AR bonus.

I can't remember which is worse with elemental with Meph, but stacking your res usually will do.Also, he should be dealt with after you've killed the other 2 as you've done before.

I do uber tristram with my berserker, and he uses Death as well. It's made in a berserker axe, but the key is having an Act 1 Faith Merc to let you reach 9 FPA.

My other gear is:
CoH (as was said, Treachery would be a good cheaper option too, especially if you need the IAS and you don't have an act 1 faith merc)
Thundergod's
Nature's Peace
Ravenfrost
Highlord's
Laying of Hands
Stormshield
Guillaume's
Gore's

That gives me 100% Crushing Blow and 100% Deadly Strike, so I am doing a ton of damage at the fastest FPA. I prebuff battle orders to level 55 before going in, and I have my resistances stacked so they remain at 75% (85% for lightning) after meph's conviction. Seperate the 3 bosses, use Howl to keep the minions off you, and keep an eye on your merc's life.
