Kira's guardian with um rune
Guardian angel with um rune or wealth if you're super pro
ebotd war pike
play super tight and you can get away with it. Mess up and merc dies fast without the ga. with ga, he can even tank hydras, 90% fire resist. But he can still get slapped , they hit hard sometimes those members, you have to stun them with war cry, many times. It hits only 10% of the time on those super uniques. But he will hit hard with ebodt.
And i twas originally my idea, to use gavel of pain on switch. I wrote often about it in threads many many years ago. So the deal is this. You run down the stairs, heal up merc n stuff. You try to herd them a little bit before you run down, so that you have nice easy access when you get up. When you get up, you immediately run up to the biggest bunch and cast war cry multiple times. Now, you hopefully stun 60-80% of them. Merc gets to work. Hey, that rhymed xD When he's taken down 2-3-4 of them, now you can freely switch to gop and cast amp damage on the rest. Usually merc now waltzes over them like a lawnmower, and you can start using find item, pick gold and sort the goods.
Usually there aren't big boss packs around, but they can happen, the vampire lords, and they can make life sour, so try to be observant and watch the loot - pick gold fast, pick the most expensive stuff, go to town, identify, sell, go back, pick stuff, tp out, go to act 4, immediately save and exit.
Don't waste your time ... that's one of my favourite motörhead tracks.
