[Nekros] is one of the only frames that can boost the loot from bosses that are immune to abilities like enemy Necramechs. This build subsumes an ability that shuts down their abilities as well to even the playing field on more difficult missions such as Isolation Vaults on Deimos.

Silence completely shuts down the abilities of enemies like Necramechs. This takes away their shields, [Reflection], and offensive options so that you can dispatch them more quickly. At the moment there is no other option that does the same thing on such a large scale.

Soul Punch is replaced as it's weak and useless for what we're trying to do with this build. Terrify keeps enemies away while you attack the mini boss.

Duration is high enough that Silence should last through the fight. It has a very fast casting time even if it runs out anyway.

Efficiency is bumped up a bit so that you can cast all of your abilities with or without [Primed Flow]. Without it you're barely have enough energy from an Arcane Energize proc to cast all of them.

Range is boosted high enough to keep all Necramechs near you under the Silence aura. Boosting it higher may be dangerous if you're farming parts as you have a maximum number of enemies that Desecrate can hit per second and high range can cause you to waste procs on enemies that are very far away rather than the difficult enemy that you just killed.

Strength is useless on this build. Your shadows from Shadows of the Dead will get torn apart even if you're at 100% Strength. They are just bodies to turn the enemies around so that you can hit weak points.

[Corrosive Projection] provides a small DPS boost through the entire mission and synergizes with multiple allies running it. Replace it and [Coaction Drift] at your own discretion.

[Vigorous Swap] provides damage and holster speed for status primers. Even melee weapons benefit as you can swap between two status proc weapons and then to your melee almost instantly even if the hostler speed does nothing to the final swap. Replace it if you decide to run Speed Holster or [Synth Reflex].

[Rolling Guard], [Adaptation], and [Vitality] allow you to stay alive against the onslaught of damage. If you're playing perfectly then you only need [Rolling Guard] and the other two can be replaced for more Duration or QoL.

[Despoil] helps our energy economy as we barely have enough energy to cast all of our abilities without Primed Flow. It hurts your survivability by a bit but it's a necessary trade-off. Max Efficiency and [Primed Flow] make this mod far less useful.

[Natural Talent] can be subbed in over a flex mod if you're having issues with the Shadows of the Dead cast time. These shadows provide distractions for the mini boss to shoot and should be up before you start the engagement.

Arcane [Guardian] synergizes with other survivability tools to keep you alive in more difficult fights. It can be replaced with offensive arcanes as you become more comfortable with the fight rotations and tools like shield gating and [Rolling Guard].
