First buy a warrior as hireling cuz Wiz&Rouge can’t be very effective as Warrior as early stages on the game.
When i was like u i climbed till 200 and started to make a tank warrior build like that (i don’t take dmg on 500th floor):
(One dodge on the equipments will be block and Total AR%,All Resist on Pet will change with CB%,Block)
Cuz i’ve already made a build like this:
Momentum MH, Satyr’s Spirit OH, Druidic Chest, Nadroji’s Helm,Faun’s Gifts&Nadroji’s Accessories with Plagued Pet.If u have nı pet don’t worry just remove Nadroji’s Helm and use Faun’s Gifts Helm with Plagued Accessory.
Remove everything about not about element,move speed,dmg(of course keep set affixes 
).Add epic element dmg% on your all items.Also add crit chance,crit dmg,luck,gf as u can do as.Definitely use BloodMagic on your Warrior cuz MP is problem for warriors.Also u gonna get DMG bonus too.Use Zealous talent on ring blessed on chest (also u can add zealous to your equipments too).Make same thing on your Wiz just change Momentum Lance to Permafrost Gaunlet.Stay 200th floor for Nadroji Equipments.Use warrior as main.Change your Horn Special to Taunt.Select Dealer Perk on your Warrior.Gice your hero pts to STR>DEX>Fortune on Skill Tree.Keep farming till reach resources to make sets like them(my Wiz’s or Warrior’s).And select Treasured Perk as 2nd.Mustn’t use hammer or Vampiric Touch+BloodMagic(on wiz) like me.I just tried my chance and got them on first time so i kept them.I think u can climb till 350th floor without my current builds.When u reached there start to try drop Eternellized,Crystalline items.U’ll make a real build then.When u got them check this out:
