Bonestorm + Shadowblight is sadly the way to go as a minionmancer. While you have bonestorm active (with the 3 aspects that buff bonestorm) and disobidience + the fortify you get from reapers you are basically immortal while bonestorm is up.
If you go with army of the dead and kalan, you must rely on the blood mist panic button and play like a glass cannon, with bonestorm you go right in the middle and tank everything because you are fortified, have a barrier and a ton of armor so you can basically roll throung NM dungeons like an all guns blazing tank which means your runs will be much faster than with army of the dead and kanlan.
I’m talking about leveling at + 3 levels, pushing on Tier 80+ is different ofc.
