Mark of the Undead

This Build was for optional end build unless your not going for Nekros Prime.

• I choose the Health Regen mostly for Defense and Survival Missions you can use a different one before using forma.

• Primed Flow + Preparation Combination so you don't have to rely too much on Dispensary at the start of the round

• [Steel Fiber] and [Primed Vigor] as a primary Defense Mods since [Adaptation] will be much useful when it reaches max stacks (you can use [Umbral Fiber] and [Vitality] but I would say go for Nekros Prime and put that Umbral mods in there instead because Umbra Forma was not easy to get)

• Hunter Adrenaline for emergency backup when you receive damage after the shield goes down you can cast Terrify quickly

• Equilibrium is like an all purpose mod for Nekros whether it's low on health or energy this mod will be useful most of the time.

• [Despoil] + Shield of Shadow is like Mod Synergy it's better for this 2 mod to be in the same set.

Regarding ARCANES
Arcane Victory and Arcane Pulse was the cheap mods you can get and easier to farm.
but if you want something more useful Arcane Energize, Arcane Grace, or Arcane [Guardian] can be your best bet.
