Act III merc for MF Hammerdin? Hello all! I'm looking for an excuse to use a different mercenary on a build (ha the things we do to entertain ourselves!). I'm wondering if an Act III merc on a mf hammerdin built for mainly Baal runs would be feasible. I was thinking a spirit sword and shield, vipermagi and shako? But I'd waste the concentration aura on him, wouldn't I? Perhaps if my resists are high enough I could plunk a few points in conviction? Any thoughts?
