I want to theory craft

So you want to do it on a budget hmm.
I would use angelic amu ring combo for that high ar, maybe could use 2xrings if I was wearing duriels shell,
so I dont have to use raven frost on the other finger for cannot be frozen.
Kira isnt bad helm for fighting mephisto, arreats isnt that pricey, guillaumes has cb and ds which will help with dmg on a budged barb and its the best melee helm imo.
Duress armor is pretty cheap and viable since it gives resists, cb, ow and dmg.
Treachery- ofc you will need this to prebuff fade, or you can accually wear it, 45ias and the fade will keep buffin.
Demon limb- ofc you will need it to enchant yourself for huge ar bonus
Goblin toes for shoes, easy to find, 25cb gg, upp them once
Draculs gloves are pretty important, unless you want to switch to life tap wand every now and then, or use marrowalk boots instead of goblins.
If you dont have draculs use life tap wand and put on LoH for fire res 20ias and 350% dmg to demons, soul drainers not bad too, since -50 monster def per hit,
But it will override your life tap every while.
Life tap wand- aim for lvl 6, 105 charges
Ofc there is still stuff like
Death set gloves and belt: cannot be frozen, 30 ias, 15@res Dont hate me for listing this...
IK set, which is usefull even if not complete, so you can use helm, boots, belt, gloves combo to get some skills, def, ias, resists, stats and ar,
though you ll have to use that life tap wand, but hey, this is budged or even untwinked right?
Beatdown sticks: there will be lot of options here I would say. I try to list some good cheap options:
Black runeword (thul io nef)- 120ed, 40cb, 15ias, 200ar, 10vita
I think this is like the cheapest option for ut weapon, you can put it in tyrant club (easiest to get 3sx), scourge (fastest But has dmg range like lightning), legendary mallet(best avrg dmg but slow)
Crescent moon(shael um tir)- in one word I would say: STATIC!!!! this will help you get the ubers down to half life pretty quick, watch though, since static is magnet for monsters,
You should lure them further from each other, or at least Mephi.
Bul kathos children:
I like this combo for frenzy barbarian its really nice, two items complete set, you get 2+all skills, 200 ar and 200%dmg to demons! Ubers are what? I dont think they are minions.
Both weapons have ias, so remember to put mythical sword to primary weapon slot bcs of its shorter range, it has 50fire res which is nice too and 20 str helps to wear the other one, sx it with shael I guess.
The offhand has 40cb and 20@res, not bad...
Bloodmoon- 50ow, underrated weapon
Lightsabre- Very fast, light absorb, mana leech
I even did ubers with azurewrath/grandfather combo but its kinda hard to find them...
Butchers pupils- never tried for uts, but if upped they are not bad
Headstriker- 100 ds on higher lvl char, can be upped too
Stormlash- this is uber weapon but its very hard to find, static, cb, ias, light absorb, probably the best weapon here
Stonecrusher- 40cb, -25 targets def, -100 def per hit (it is slow though and not easy to find either)
Put alot of crappy resist, life, ar charms in your inv, anythink you can find
Skills:
Frenzy 20
Battle orders 20
There are few options now:
Dual wield (synergy)
Taunt (synergy)
Weap mastery (awesome stuff)
Howl
Its up to you if you prefer max synergies for higher dmg but high lvl howl is awesome crowd control tool and since you frenzy, you ll be hitting mobs around your primary target,
So if you howl them away you ll be hitting uber boss with bot weapons.
I guess I would go with mastery and howl putting the rest points into dual wield, since it doesnt need mana on lvl 10 or so, and that baal is anoying with mana burn.
Choice is yours.
Ofc put point in iron skill and natural resists.
You can put one point into zerk to fight off imunes and if you maxed howl thats a synergy to it.
I wouldnt waste points in increase stamina and speed, since you are barbarian and frenzy you Got stamina and speed Within you.
So far for my theory craft, there are ofc etter options but I was just talking low budet.
Ideas, notes and criticsm ecouraged. C ya ;
