The Aspect of Nyx turns the Black Coat into a summoner: activate its Omega Boost to produce Nightspawn that fight at your side.
The Aspect of Nyx gives the Black Coat a summon engine, letting you produce Nightspawn that fight alongside you once you activate its Omega Boost.
Instead of relying only on the coat punch and homing missiles, you trigger the Boost and spawn dark allies that add a second stream of damage. The aspect scales how hard those Nightspawn hit, doubling their damage at the top rank.
It is the Black Coat option for players who want a build that fights for them, layering summon pressure on top of the weapon already flexible kit.
This guide covers how the Nyx Nightspawn work, the rank scaling, the best build, and when to pick it over the other Black Coat aspects.
an Omega Boost lets you produce Nightspawn allies after you activate it. the Black Coat, adding a summon layer to its missiles and punch.
Magick sustain and boons that let your own attacks keep pace with the spawn.The Aspect of Nyx grants an Omega Boost that, once activated, lets you produce Nightspawn, dark allies that fight alongside Melinoe.
On the Black Coat, you already mix a melee punch, a force-field Omega Attack, and a six-lock homing-missile Omega Special. Nyx adds a summon layer: trigger the Boost, then spawn Nightspawn that deal their own damage while you keep firing the coat normal kit.
The aspect scaling stat is Nightspawn Damage, which the wiki tracks rising to plus 100 percent at rank VI. That means a fully invested Nyx build leans heavily on the spawn for damage, turning the Black Coat into a hybrid of weapon fire and an active summon.
Activate the Boost early in a room, not at the end. The Nightspawn need time on the field to earn their damage, so producing them as a fight starts gives them the whole encounter to work rather than spawning them as the last enemy falls.
The aspect scales Nightspawn Damage, so each rank makes the allies you produce hit harder.
| Rank | Nightspawn Damage |
|---|---|
| Rank I | +15% |
| Rank II | +30% |
| Rank III | +45% |
| Rank IV | +60% |
| Rank V | +75% |
| Rank VI | +100% |
Ranks II through V each cost Nightmare, and the rank VI jump to plus 100 percent unlocks through the Hephaestus Legendary boon Premium Service. Because the Nightspawn are the build payoff, the ranks matter more here than on a stat aspect: at rank VI your spawn hit twice as hard as at rank I, which is the difference between a side effect and a real second damage source.
Invest fully before you commit to a Nyx run. At low ranks the Nightspawn chip in modestly, but the rank VI doubling is what makes them worth building around, so treat Nyx as a payoff aspect you rank up rather than a quick pickup.
The strongest Nyx build keeps the Boost and Nightspawn rolling while your own Black Coat attacks fill the gaps.
Prioritize Magick sustain so you can activate the Boost often, then take boons that keep your missiles and punch contributing alongside the spawn. Crowd control helps the Nightspawn connect, and a defensive layer keeps you safe while they do the work.
Aspect of Nyx (Boost produces Nightspawn) Zeus (lightning on the homing missiles)
Apollo (damage and Daze on the punch)
Magick regen sources (keep the Boost online)
Hephaestus blast (group foes for the spawn)
Ares blade rift (extra damage while you reposition)In practice this build plays like the Black Coat with backup. You fire missiles and punch as usual, but a pack of Nightspawn adds steady damage in the background, and at rank VI that backup hits hard enough to carry rooms on its own.
The Nyx build wants Magick sustain, boons that keep your own attacks relevant, and control that helps the Nightspawn connect.
Zeus on the homing missiles keeps your personal damage high while the spawn work, and Apollo Daze protects you in melee. Hephaestus blast and Poseidon knockback group enemies so your Nightspawn focus a clump rather than scattering.
The aspect also pairs thematically with 
Selene Moon Hexes, since a Hex gives you another button to press while the spawn fight. In practice, Magick regeneration is the real enabler, because every Boost activation is another wave of Nightspawn.")
Do not stop attacking once the Nightspawn are out. They are a supplement, not a replacement; your missiles and punch still do the bulk of the damage at most ranks, so the strongest Nyx players fight actively while the spawn add pressure.
Pick Nyx for a summon build, and pick a different aspect for a free Hex, aggression, or Special scaling.
The Aspect of Selene grants Sky Fall, a free Hex, and is the strongest all-round Black Coat aspect for most players. 
The Aspect of Melinoe speeds your Attacks, Sprint, and movement for aggressive play, and the hidden Aspect of Shiva absorbs Special blasts to grow Destructive.
Nyx is the niche summon pick, best when you specifically want Nightspawn fighting alongside you rather than a stronger personal kit. For raw power most players take Selene; Nyx is for the summoner fantasy. The full Black Coat weapon guide compares all four aspects in depth.
On the Black Coat, the Aspect of Nyx grants an Omega Boost that lets you produce Nightspawn, dark allies that fight alongside you. The aspect scales Nightspawn Damage, rising to plus 100 percent at rank VI, so the spawn become a real second damage source.
The Aspect of Nyx is an aspect of the Black Coat, Xinth. It adds a summon layer to the coat's existing kit of a melee punch, a force-field Omega Attack, and six-lock homing missiles, turning it into a hybrid weapon-and-summon build.
Prioritize Magick regeneration so you can activate the Boost often, take Zeus on the homing missiles and Apollo on the punch to keep your own damage high, group foes with Hephaestus blast so the Nightspawn focus them, and rank the aspect up fully.
Nightspawn are the dark allied summons the Aspect of Nyx produces after you activate its Omega Boost. They fight alongside Melinoe and deal their own damage, scaled by the aspect's Nightspawn Damage stat up to plus 100 percent at rank VI.
It is a strong niche pick when you want a summon build. The Nightspawn add steady background damage, and at rank VI they hit hard enough to carry rooms. For raw power most players prefer the Aspect of Selene and its free Hex.
Activate the Omega Boost again, which costs Magick. The more Magick regeneration your build has, the more often you can trigger the Boost and produce fresh Nightspawn, so Magick sustain is the key to high summon uptime.
Pick Nyx if you specifically want Nightspawn fighting alongside you, and pick Selene for the stronger all-round build thanks to its free Sky Fall Hex. Selene is the higher-power default; Nyx is the summoner-focused option.
Rank VI gives plus 100 percent Nightspawn Damage, double the rank I value, which is what makes the spawn a real damage source rather than a minor side effect. Rank it up fully before building around it on a deep run.
