Do you want to farm Necramechs efficiently, but [Hate] other people? Well have I got the solution for you! [Octavia] may be the queen of killing mechs with your eyes closed, but only [Nekros] can give you a chance for extra loot.

Ensnare only works once per mech, so you need a good chunk of duration to make it count because you can't recast it.

The given range and duration let you cast Ensnare from a safe distance and kill the mech before it wakes up. [Health Conversion] and [Adaptation] let you comfortably survive the infested waves before the actual mechs. Any additional tankiness (egs. [Shield Of Shadows]) will detract from your other stats and will probably not be enough to help you survive the mech's bombs or damage [Reflect] anyway.

Recommended to use a radiation heavy attack [Stropha] with this build. [Steel Charge] and Arcane [Fury] will further boost your damage. [Stropha] is highly recommended over [Redeemer Prime] because the projectile width and punch through really help to hit the mech's arms. If you attack from the side of the mech you can hit both arms with a single shot to greatly increase your damage.
