I'm currently running A5 Merc with the following:
- Qarak's Will (old version with 250% Bloodlust damage)
- Khazra Plate
- Beads of the Snake queen Ammy
- Warmonger for helm
- Blind Anger Gloves
- Champion of Triune belt
He hits like a truck and really helps with farming in Dunc/Fautz, but he does die in some of the tougher parts of the game like higher rifts. Does anyone have recommendations for their best merc setups? I hear A3 Merc is really good as well.
