Wondering if anyone has time to explain some gf barb aspects.

Currently my lvl 75 can't kill anything using Berserk. HC so using the best I can, death cleaver and rune master.

But I do pretty much no damage to the counsel.

Oath runeword would be better until you swap to grief. Maybe that unbending will too

You are supposed to use your merc as main dps, maybe that changed in the last couple years since the last time i played a gf barb, but i doubt it

Yea.. I was trying to do some version where I do the damage even if I lose gf efficiency, but I've never made one before and it's obvious now I have no idea what I'm doing.

just spam that stun on council while your merc kills, wearing alibabas or lemmed cs, just equip your emrc with a weapon that has no cold dmg so corpses dont shatter so you can hork, eth bonehew is a good cheap option, you probably dont want to spend a lot in a gf barb

Berserk only if you run grief. If not, ebotd merch and you leap.

lvl 75 is the problem, go lvl up to 85 or so and you will see it just gets easier as both you and merc will better off.

but as others have said, let your merc do the killing , but help him with stuns from war cry
