For your Uber set up, I might suggest Goblin Toe boots for the Crushing blow, might help speed things up a bit.

Gores are still a good choice of course

Either one
Whichever I find first.

Go P8 on dclone and if you can't kill, then you can't. No need to go easier. This is p8.

Easy for you to say mister -.-
Melee is a lot easier on ubers than casting spells.

Clones regen is the problem
Get something with Prevent monster heal for your merc (just keep him alive ^_^) and you shouldn't have too much trouble, even as a caster.

agree

PMH doesn't work on ubers. OW is the way to go (malice)

This, PMH doesn't do anything at all on DClone, gotta have OW. Make sure your mercs IAS is high as well.

lol ofc, i refered to post cause thought of the "must stop their reg"
ow is the way

DC and Ubers can be killed both by melee sorc (zeal or regular) or casting sorc, although Blizzard is probably not the best choice (see your other topic).

Regeneration can be stopped by merc or sorc :
merc using poison or open wounds (duress for example, or Um/p.Emerald in Reaper's toll),
melee sorc using any source of OW,
casting sorc using damage per frame (as main attack or as anti-regeneration attack) : firewall, meteor.

While open wounds always works, poison or fire damage need res < 100% to be effective :
Lilith (185%) and Uber-Mephisto (110%) are immuned to poison (the last can be damaged by poison only if level > 9 Lower res is cast),
Diablo (110%) and Baal (115%) are immuned to fire, but an Infinity merc can take care of that.
