[Nyx] has several ways to crowd control and kill enemies by using secondary effects from her base abilities. We don't use a subsumed ability in this general use build but there are several small QoL improvements gained from different choices.

Mind Control is usually the ability that should be replaced unless you're doing a gimmicky [Mind Freak] build. Any of the other 3 abilities can be replaced there.

[Assimilate] allows you to drop survivability mods to focus on rounding out the kit. Make sure that you supplement your decreased movement speed with some form of tertiary movement like void dashing or melee combos. Any of the other augments can be substituted in but you'll be relying on your CC abilities to stay alive.

[Intensify] can be replaced with [Augur Secrets] to strip 99% of armor rather than 100%. Against the vast majority of enemies this allows you to abuse counter elements to do more damage than fully stripping their armor and losing Health Type modifiers. This isn't a good decision against shielded enemies due to shield gating.

[Fleeting Expertise] can be replaced if you're confident with your energy economy. Duration is the easy call but [Natural Talent] is useful on spam heavy builds.

[Enemy Radar] mods help you and your team to find enemies. The nature of this build forces you to sometimes track down stragglers.

Arcane Avenger can still proc even while under the influence of Absorb. Any other arcane can be chosen to suit your playstyle.
