Is there a way running ancient tunnels with barbarian(item finder)

HEY yo diablo 2 community whats upp i hope u all are doing fine.
I was thinking is If it could be a way to kill those unique and champ packs on ancient tunnels with barbarian but guess what physical and magic immunity
I need a build idea for running ancient tunnels with it if that idea works and run per seconds is 0.40 avg i would give that guy reward in terms of high rune

 

Throw a Reapers Toll on your Act 2 Merc

 

@Fatty180 I'm sure people won't complain about it, but you don't need to offer rewards for advice/info. Many people are perfectly happy to assist you free of charge.

As Dark already mentioned; using a source of decrepify (like a Reapers Toll on merc) will work well to help lower phys immunity.

 

Crushing blow and Open wounds %. Speaking from personal experience, it certainly works. A. keeps them bleeding and B. CB will always take a chunk of life physical immune or not. Been there, done that and will give examples if needed. I main a level 94 Barbarian who is a 1 point frenzy/ww wonder. If I can do it, surely you can as well. Good luck.

I run the following in optimal times with a Barb TM equipped:

Tristram, Countess, Andy, Ancient Tunnels, Summoner, Travincil, Meph, RoF/Chaos, Frigid/Bloody bosses, Nihlathak, Baal.

My characters are designed with the intention of running anything in the game, so results may vary upon user.
