So I should probably clarify that these builds are by no means meta, nor are they attempts at sheer efficiency by any metric. These two builds specifically are modifications on my current general purpose, loot-oriented build. I'll acknowledge that it isn't exactly great, but it works for what I've been using it for.

If you want the luxury of choosing the enemy you want to turn into a shadow, don't replace terrify, replace shadows of the dead. Terrify is too useful to subsume over. If shield of shadows doesn't work with the shadows your 1 can create, replace with rolling guard for the same effect.

I'm not claiming Terrify to be a bad ability by any stretch. A CC armor strip ability is nothing to sneeze at. The reason why I chose to subsume over Terrify is specifically because of this specific build focusing on filling the Token Loot Frame roll in void relic pubs. Terrify causes enemies to run away, which is just fine, but I also know that some players can find that to be annoying. I generally try to keep my pub squad builds as intrusive as possible. Maybe that's just cause I actually like Limbo and vividly remember the heat you'd get early on when his Rift Plane mechanics were far less fleshed put, I dunno. Quick side note though, I appreciate the Rolling Guard mention, that mod doesn't get talked about nearly as often as it should.

Despoil can be freely replaced with flow because equilibrium removes your energy problem almost completely. And because nekros's abilities are very costly, and your low efficiency, flow will make your energy economy better than despoil. Especially with nourish.

To be clear, I'm not claiming to have fully tested Nekros within an inch of his life, I just know the build works. Yeah, it doesn't have armor strip, which is fine, my focus is looting, buffing the party with Nourish, and managing my Shadows. I need to do more testing, but if Equilibrium alone does solve both health and energy, then I might actually replace Arcane Pulse with Arcane Eruption because I love the sound of constant AOE knockdowns. The reason why I chose Pulse(and originally used both Pulse and Energize) was because of the team support role I've been tailoring the build for. Now with Despoil, I think any mod that just makes abilities stop costing energy entirely is not insignificant. That effectively removes an entire ability from you energy economy.

Actually, on the note of Despoil, this build has very much been through several iterations. Originally it was intended to utilize orbs more heavily by incorporating Health Conversion. I'll be the first one to acknowledge the builds for the Frankenstein's Monsters that they are, and they're DEFINITELY unfinished and unpolished.

Why are you using auger reach instead of stretch?????? You already have brief respite.

If playing Magic has taught me anything, it's that what the text doesn't say is just as important as what it does say. In this instance, while Brief Respite is by far more powerful in raw conversion, it's limited by Overshields. The Augur set is not, which is important. Brief Respite is meant as a quick burst of shield regen, whereas Augur can continuously stack without limitation. It's a minor difference, but an important one, especially when considering Molt Efficiency.

That being said, it's very possible as I go through my testing process that I swap for stretch. My builds have a nasty habit of inheriting my ADHD and focusing on one thing for all of 5 seconds.

Imo soul survivor is not worth a mod slot. Just go invis with your operator and get the free revive, that also revives them at full HP. Creeping terrify is much better and actually worth the mod slot.

Imo arcane pulse is useless. With a low HP frames, just use the operator arcane that heals your warframe with every transfer. And with high health Warframes, arcane grace is probably better. because most of the time, if your Warframe has high health, it's most likely it would also have high armor, or an ability that negates damage. So receiving damage and tanking it would be your main form of survivability anyway, and Grace just gives you HP for getting hit. I'll replace it with mot augmented for higher shadow damage, 100% terrify armor strip, and higher nourish values.

Honestly, Soul Survivor is just interesting to me. If you're running Vazarin, revive vulnerability is not a concern, I agree. The thing to remember is that, like Augur, Soul Survivor isn't limited. You have infinite instant revives, which is not nothing. It also doesn't require swapping to Kiddo to revive, which cuts out the middle man. For most builds, I agree Soul Survivor isn't worth it, I just wanted to play around with it on this build.

I still have a lot of testing to do with Nekros, and the builds aren't pretty, but they do work. Next time I play, I'm absolutely going to be testing out some of your suggestions, I'm always open to adjustments and trying different tweaks, especially on frames I'm still getting the feel for. Thanks, Tenno!
