You can go Insight Merc as Zerk anyway? Unless you're doing CS with the Act 5 Merc build.
105 is definitely worth it either way.

Go with a3 cold merc (lawbringer, stormshield, guardian angel and kiras or coa)

No hork if you shatter corpses
You'd be plenty safe with the A5 Merc honestly

not going to hork when i become chos barb. Going to make megafast runs but i will probably use seal drop thing to get more drops

a3 cold merc is mush safer than a5 merc...

wish I could have a barb like yours lol but I'm really tired of this game. Just thinking about continue mine make me sick lol (done nightmare, I have to farm meph for upgrades)
Can't wait to see yours in chaos sanct

You'll have Howl + Stormshield + Barb HP + Decrepify slow + Sanctuary with the A5 variant, that's really fucking safe haha.

With 105 swap you have very fast hork and 50%+ chance. To each his own though, good luck will be watching.

No decrep vs decrep is safer. Ok boss.

If you have like an eth elite base he's pretty tanky and A5 mercs also have like steroid life rep compared to the others. Since Lawbringer comes with LL and he's (for the most part) hitting -50 physical res targets. He can also contribute to boss killing with CB if you're not doing only Left/Right seal runs.

So much to say about A5 guy LOL

I have to say that he marks a point, I would choose act5 versus act 3. Anyway I prefer act 2 cuz might aura + Reaper's Toll. Just shooting howl with your fcr + fhr (if you use 2x spirit ;)) is save enough for me i think.

sry for spam!

Berserk is magic damage and not effected by physical resistance.
Sanctuary is nice AF for a HC toon trying to aggressively run CS. Might is nice but I think I'd prefer Sanctuary for CS specifically.
