[Overview]

This build maximizes [Nyx]'s ability to control the battlefield through mental manipulation, while hitting that 100% armor reduction on psychic Bolts. You're also an night unstoppable terminator, and that's just grand.

ABILITIES

Passive
Gaining better crit chance the more we wreak havoc means we want high crit weapons to really throw those red numbers through the roof. Use whatever crit guns you like, I personally use the [Soma Prime] with its Incarnon form and it melts Steel Path with ease.

Mind Control
With the ability to buff the targets we take from the enemy, this ability is now quite a good powerhouse. With the right weapon, even taking a lowly basic unit can be a power house. Its a great way to dish out damage and also take some of the heat off of us. Ideally you want to prioritize taking control of stronger enemies for maximum damage and tankiness. The damage buff and 4 second window are not affected by any of our stats, so you can't make it terrible on accident.

Psychic Bolts
As someone who has been playing [Nyx] since her inception, it is still dumbfounding to me that Psychic Bolts is good. This is very simple. At 125% power strength, Psychic Bolts will strip 100% of the armor or shields from the target. The bolts home in on targets, it only takes a single bolt to rip all of that armor away, and we get 6 bolts at max level. So you now have a great way to handle those pesky level 150+ Corrupted Bombards!

Chaos
Our best crowd control option. Everyone looks at everyone else and decides it might be a good idea to kill everyone. Now this doesn't mean they still won't target you, but it lowers your threat level, making it easier for you to murder everyone while they're distracted. Obviously if there's only you and one guy under the effects of Chaos, you're gonna have bad time. Targets that are immune to Chaos are stunned for a few seconds, so in a pinch, you can use it to escape or turn around a bad situation.

Absorb
With the recent update, Absorb is great for tanking, especially with Assimilation. This is our bread and butter for surviving in Steel Path. Turn it on at the start of your mission and turn it off when you need quick bursts of speed.

MOD CHOICE

Aura
Since Psychic Bolts can strip the armor off of high level enemies with little to no effort, [Corrosive Projection] isn't needed for this build. Instead you have your pick of what fits your style. I use [Worthy Comradery], which at the moment is not on Overframe.

Exilus
Since this build now revolved around becoming a terminator with mind melting psychic might, you want as much energy as you can muster. [Preparation] gives us max energy right out the gate, allowing us to immediately use our Absorb with tons of energy to keep us alive.

Survivability
Keeping Absorb up as much as possible is your survival tactic. With [Equilibrium], gaining energy is much smoother and thus easier to keep the bubble going.

Strength
The goal is to hit 125% power strength, as 125% is the magic number that allows Psychic Bolts to get 100% armor stripping, making high level targets a laughable pile of wet tissue paper. There's no real reason to go higher than 125%, so .

Duration
Duration is important for [Nyx], and after her rework can be more an important than ever. Long times for Mind Control targets and Chaos means you keep your passive buff longer, which means you kill quicker. In normal game play this might not be as noticeable as it in in Steel Path, where hordes of enemies suddenly turning on each other in other rooms allows you to easily start picking off targets.

Range
One of our most important stats, farther range means easier targeting for Psychic Bolts and more available enemies for Chaos.

Efficiency
Unfortunately there is really no room to make our abilities cost less, not without sacrificing something else that we would deem more important. If you really want to make your abilities cost less, I would suggest turning down Duration and/or Strength and use Arcanes to make up for it.

HELMINTH ABILITIES

While I enjoy all of [Nyx]'s kit, there are those that tend to not like Mind Control specifically. Since it's the only ability that we can really do without, I figure I'd list some of the fun alternatives.

Petrify
If you build around [Ore Gaze] it can get you more loot, importantly more energy to keep Absorb up. This does mean you need to use Arcanes and Archon shards to mitigate whatever mod you remove for the augment though.

Vial [Rush]
You move slower with Absorb, so the burst of speed is useful.

Dispensary
Probably the most useful one of the bunch, throwing out energy and ammo is great for the build.

Chyrinka Pillar
With guaranteed Radiation procs, this is great for keeping [Nyx]'s passive going.

Reave
Another decent choice if you want bursts of speed.

Roar
Since we primarily use guns to kill, this is a great choice to not only buff your own damage output, but those of your team as well.

Breach Surge
More crowd control, plus the Surge Sparks deal radiation damage.

ARCANES

Energize
Helps keep Absorb up longer while also allowing you to freely cast your abilities more often.

Molt Efficiency
Since we use Absorb to [Protect] us, our shields are always active. This means you can keep Mind Control targets well over 100 seconds and have over a minute of Chaos time in long missions.

ARCHON SHARDS

Crimson
Lots of variety here. You can use these to meet your 125% Strength requirement if you'd rather have other mods in the build. You can add yet more duration. You can increase the crit chance of your favorite secondary even more.

Amber
Only really useful for the increased effectiveness of energy orbs or to speed up casting speed.

Azure
If you want tons of energy at start, grab increased energy.

PUTTING IT ALL TOGETHER

[Nyx] isn't hard to play once you have everything in order. When you get into a mission, immediately use Absorb so that you are untouchable. When you find enemies, cast Chaos, and while they are stunned, use Mind Control on the target of your choice and beef them up with your weapon of choice. Throw your Psychic Bolts out at targets with high armor and melt them with ease. Repeat these steps as needed until you have sated you thirst for violence like the void demon you are!
