Re: How do you usually handle high repair cost for runeword armors?
How much "+Extra Gold" do you have? Can you list which locations you run for gold in each game?

Lastly, single game or multiplayer game?
Don't remember correctly, but it's something like 1500% extra gold, though I could get to like 2000 if I bothered. I do the killing myself because I don't trust merc's amoebic AI to do the job

Build is a berserk babo with grief/rhyme. I do use a lot of warcries, though: level 10 warcry to make minions stand still and battle cry to smooth out the big 3 when they spawn with fana or xstrong mods. Merc uses insight, so that I can deal with mana burn and keep a good refil rate for warcrying. By the way, the big 3 can also get stunned from warcry, but the odds are like 5 or 10% per cry.
I get like 400-600 k per run and it doesn't matter if it's single player or multi player: the council goes down easily in both cases... lol. Ok, maybe 5 mins is an exaggeration, but it's certainly not longer than 10. I only run the hell council. Besides gold, you can get some pretty nice rares if you use a bit of mf (for instance lem lem alibabas on weap switch). Last ladder I got a mara 30 and a soj without playing much.
