UPDATE OCTOBER 2024
[Nova] rework will allow you to use Slowva and Speedva simultaneously and changes the strength threshold for maximum slow and speed to 150% strength. Her new passive will also cause kills on slowed enemies to have a 15% chance to drop health orbs which helps with energy economy via [Equilibrium], whereas kills on sped up enemies have a 15% chance to drop energy orbs. Killing 20 slowed enemies on average drops 3 health orbs which is equivalent to 165 energy.

The updated augments [Neutron Star] and [Molecular Fission] now give additional useful effects rather than previously used exclusively for health tanking.
1. [Molecular Fission]: [Molecular Fission] now allows Null Stars to apply Molecular Prime to enemies hit directly by a star, so Null Stars will automatically seek enemies out in approx 12-20m radius and apply molecular prime if not already primed (or alternatively seek multiple enemies at once if you press 1 with [Neutron Star] to release all particles). This means you effectively can apply Molecular Prime against nearby enemies WITHOUT recasting Molecular Prime nor needing to wait for the slow spread of the wave to touch targets, which is extremely useful for a more mobile playstyle.
2. [Neutron Star]: [Neutron Star] causes all remaining stars to seek enemies upon recasting 1, meaning you can prime multiple nearby enemies with Molecular Prime on demand. In addition [Neutron Star] applies forced HEAT status in an AOE which causes a brief stun animation which is significantly prolonged by the slow from Molecular Prime while also partially stripping some armor over time (up to 50% after 2s - which is effectively a 3.7x damage multiplier against armored enemies). If you subsume Nourish, you can actually apply viral to each [Neutron Star] AOE and rapidly and passively prime enemies all around you with both viral and heat. Note however the heat statuses are slightly detrimental to weapons that rely heavily on Heat status DPS since you will cause "reverse heat inherit" where heat procs from a DPS weapon inherit the lack of heat mods on [Neutron Star], if [Neutron Star] causes the initial heat proc on an enemy.

PLAYSTYLE

1. Tap cast 4 (molecular prime) to slow enemies down by 75% or hold cast 4 (molecular prime) to speed enemies up by 75%.
2. Tap 1 to activate null stars, occasionally recast 1 to shoot all null stars to hit enemies with heat procs and molecular prime
3. Use 3 for quick map traversal and also as a shield gating tool while simultaneously escaping enemy fire
4. Use 2 for low level nuking

SURVIVABILITY

Shield Gating
In higher level steel path or endurance steel path (e.g. over level 500), we need to utilise a combination of shield gating and crowd control to survive. Shield gating is achieved via [Brief Respite] and Augur Mods to generate shields by casting abilities. Without [Catalyzing Shields] but with [Brief Respite] and about 3 augur mods (e.g 1 on frame and 2 on pistol), each cast of 2 gives about 0.9s gate, each cast of 3 gives about 1s gate and a cast of 4 gives 1.45s gate. With only [Brief Respite], casting 1 gives 0.5s gate, casting 3 gives 0.8s gate and casting 4 gives 0.9s gate. Adding [Catalyzing Shields] means every single ability cast gives enough shields for a 1.33s gate. Rolling Guard is very useful to provide additional i-frames as well as status cleanse. Crowd Control is easy due to Molecular Prime's slow combined with forced heat procs from [Neutron Star] which is automatically released as enemies get closer.

Tanking
Since Nullstars provides 90% damage reduction and now applies to both shields and health, keeping 1 active at all times (which is basically 100% with [Molecular Fission]) allows you to passively tank low levels (e.g. base SP up to level 500) quite easily. Swap [Rolling Guard] for [Adaptation] and add Arcane Blessing and [Guardian].

BUILD SPECIFICS

Duration
Duration affects the final expansion range of Molecular Prime as well as the number of null star particles. At approxiamtely 200% duration, Molecular Prime spreads 65m and Null Star has 24 particles. This means pressing 1 (with [Neutron Star]) can spread 24 stars to hit up to 24 enemies and apply Molecular Prime.

Efficiency
Neutral efficiency allows you to cast wormhole and molecular prime with relative frequency, although the [Molecular Fission] augment will allow you to passive apply molecular prime via null star particles. [Nova]'s passive also means you can generate tons of energy via health orbs and [Equilibrium]. This means you can run between 45% efficiency to 100% efficiency depending on preference. I prefer 100% efficiency if using wormhole alot as it is a very expensive ability or in endurance as you will be using alot of abilities for shield gating, and 45% efficiency for more casual missions where you don't need to cast alot. See this low efficiency higher range variant: https://overframe.gg/build/739390/

Range
Positive range increases the range of Wormhole, radius of Antimatter Drop and seek radius of Null Star and explosion radius of [Neutron Star]. You can adjust this between 145 to 235+ if you have the capacity.

Strength
150% strength is the threshold required for 75% slow and speed. Without shards you can use some combination of [Umbral Intensify] + [Power Drift]. WIth shards you can use [Augur Secrets] + two crimson shards. You can also use Precision Intensify if you prefer but then you don't boost the damage of 1 or 2 or the helminth you subsume (e.g. Nourish).

Aura
- Brief respite helps shield gating

Exilus
- Power drift to help hit thresholds
- Primed sure footed (best in slot but needs additional forma and login reward)
- Escape velocity or Prepration for speedrunning

Flexible Slots

• Rolling guard is optional but helps clear status effects and gives i-frames.
• [Catalyzing Shields] if optional since it allows you to have a full 1.33s gate after casting any ability.

Arcanes
Very flexible:
Molt Efficiency - extra duration
Arcane aegis - optional for passive shield regen/lazy gating
Energize is optional for energy sustain.

Helminth

Subsume over either 2 or 3, depending on if you prefer to be mobile with Wormhole or not.

Nourish - Gives energy multiplier, viral dmg boost to weapons and also adds viral damage/status to Null Star particles allowing 1 to passively prime viral in a huge AOE. Can adjust efficiency if you prefer to run at 45%. For a meme Neutron star DPS build with Nourish see : https://overframe.gg/build/442240/

Silence - Prevents eximus and acolyte abilities, stuns enemies briefly which is prolonged by slow from Molecular Prime

Pillage - Strips armor and returns shields for shield gating

Archon Shards
TWO Amber Cast Speed - greatly improves the feel of casting Molecular Prime
ONE or TWO Crimson Tauforged Strength - gives strength to hit 150% strength threshold, allowing you to drop Power Drift or even Umbral Intensify for Primed Sure Footed + Augur Secrets
ONE or TWO Crimson Tauforged Duration - adds more duration for molecular prime spread

WEAPONS

Molecular Prime's explosions can inherit many special effects such as the 2000% multiplier on 50% of non-crits from Incarnon Weapons as well as the % health augments such as Acid Shells Sobek, Thermagnetic Shells Detron, Vulcan Blitz Jat Kittag and Entropy Detonation Obex.

Each antimatter drop orb can absorb a maximum damage of 25,000 (not affected by crits or status) and output a maximum of 200K damage as radiation damage. Weapons that can easily hit 25,000 raw damage in one shot include Felarx, Opticor, Exergis, Tenet Arca Plasmor and Tigris Prime/[Sancti Tigris].

Here is a brief demonstration of the extreme crowd control offered by the build, and how to survive using only shield gating:
