This a pretty standard [Nekros] build except the Edition of [Mag] Pull.
Why [Mag] Pull?
[Mag] Pull allows [Nekros] to use the Mod [Greedy Pull] which not only allows [Nekros] to easily collect loot but it also bring all health orbs to him allowing him to always active his [Health Conversion] x3 with a single cast of the ability. Also who wants to have to run in the hall to collect their loot on an afk farm, just pull it too you, congrats you can be lazy now! My main use for this is Steel Path to secure i pick up all items and can wait for kavat buff to grab steel essence without worrying about despawn.
As i said besides the [Mag] Pull this build is pretty standard so i'm not gonna bother explaining the rest of the build hope you guys enjoy the build!
