Info
- Nova expends
25 energy to create 
6 / 8 / 10 / 12 antimatter particles that orbit her and automatically launch themselves one by one every 1 second at enemies within 
? / ? / ? / 10 meters inflicting 
? / ? / ? / 200 
Blast damage with 100% status chance. Each particle persists on Nova indefinitely until launched, granting her 5% Damage Reduction as they orbit her.
- Damage reduction is capped at 90%.
- The particles benefit from generic increases to weapon base damage, such as from
Arcane Arachne, 
Holster Amp, and Vigorous Swap, but not from weapon class specific increases like Steel Charge or Rifle Amp.
- The particles can also benefit from flat critical chance, such as from
Covenant or 
Arcane Avenger. However, they have a critical multiplier of 1x, so sources of critical damage like Tenacious Bond are required for any effect on the damage. - Most elemental damage boosts, such as Shock Trooper, have no effect.
- Valence Formation does apply both its effects.
Nourish applies both damage and 
Viral elemental weight that will compete with the innate Blast of the particles.
- The particles can also benefit from flat critical chance, such as from
- While active, a counter becomes visible on the ability icon that displays the number of available particles.
- Null Star has a 2.5 second cooldown between casts
- Nova cannot be knocked down while casting Null Star.
- Ability Synergy: With Molecular Fission equipped, enemies killed while affected by
Molecular Prime will restore a Null Star charge with a chance to restore a second charge. - Subsuming Nova to the Helminth will offer Null Star and its augments to be used by other Warframes.
- However, Subsumed Null Star's damage reduction caps at 75%.
- If
Garuda subsumes Null Star or Nova subsumes 
Blood Altar, then the particles will not target enemies currently impaled by Blood Altar.
Augment
- Main article: Neutron Star
Neutron Star is a Warframe Augment Mod for 
Nova's 
Null Star that allows it to inflict 
Heat damage with guaranteed status effect in a radius and recasting the ability will disperse currently active particles to seek out enemies before being replenished. Neutron Star's seek radius is doubled than that of Null Star's.
Tips & Tricks
- 90% damage reduction can be achieved with 150% strength or duration, as long as the other stat is not below 100%. Going beyond this is still useful, as it provides a buffer when particles are used up.
- When you are full on energy and come across extra energy spheres laying on the floor, you can cast a "free" Null Star and instantly go back to full energy. This allows you to easily keep stars active for each encounter.
- Stars will launch themselves at unaware enemies, alerting them if they survive. This makes this ability sub-optimal for stealth oriented missions.
- Each particle will stun on hit, allowing you to continually stagger a target while you attack them.
- Defensively, it is wise to use it before reviving an ally or accessing a terminal, as you are very vulnerable when doing either. Activating Null Star beforehand can stun or kill any enemies nearby that decide to attack you, preventing you from taking a lot of unnecessary damage.
- On higher enemy ranks Nova may wish to use the skill in the same manner as
Rhino's 
Iron Skin and recast it every time her damage reduction dips significantly below 90%, as this will prevent her from being blindsided by enemies that are stuck in corners or behind obstacles. This is particularly important in Grineer tilesets because infantry will often jam themselves into corners on either side of the round doorways and open fire as soon as the player passes by. - To focus on keeping Null Star particles for damage reduction, it can be beneficial to have Ability Range lower than 100%. Lower range will prevent particles from seeking enemies at a distance. This will however hinder her other abilities, particularly
Antimatter Drop. - Null Star particles will seek deactivated Bursa in range. It is advisable to stay away to prevent wasting the particles.
- The Molecular Fission augment will allow Molecular Prime to restore up to two charges of Null Star per enemy killed while under its effects.

Patch History[]
Update 37.0 (2024-10-02)
Null Star Changes:
- This ability is now recastable!
- As this is Nova’s main source of Damage Reduction, players were incentivized to reduce Ability Range if they wanted to keep as many Null Star particles as possible. With the ability to recast to maximize your Damage Reduction, DR-minded players have more build diversity available to them.
- Increased base particle count from 6 to 12.
- 18 particles are still needed to maintain 90% Damage Reduction, but it’s now much easier for players to hit that cap.
- With the increased particle count, the VFX will become more subtle the more particles you have. These particles will also dissolve while aiming down sights to prevent them from obstructing player view.
- Damage Resistance from Null Star now applies to both Shields and Health (previously only applied to Health).
- Changed damage type from Slash to Blast damage, with a guaranteed Blast Proc. Base Null Star damage has also been increased from 150 to
300(Despite the patch notes, Null Star does 200 damage). - With the above improvements, Null Star when applied via Helminth is now altered and has its Damage Reduction capped at 75%.
- This was previously 90% – we’ve reduced it in light of the changes above and to have it fall in line with the diminished effectiveness of Mirage’s Solar Eclipse Damage Reduction.
- Seek Range reduced from 7 / 8 / 10 / 12 to ? / ? / ? / 10 (unlisted)
- Neutron Star (Augment) Changes:
- Recasting will cause remaining particles to seek out enemies, and then replenish the particles orbiting Nova.
- Heat Damage and guaranteed Heat Proc now apply to all Null Star particles, not just the ones sent out via recast.
Hotfix 31.3.1 (2022-03-29)
- Fixed being able to hit 100% invulnerability when combining Nova’s Null Stars and Helminth’s +100% Duration Invigoration.
- The usual modding limit for maximum Duration on Null Star would allow a maximum of 90% damage reduction. But with the addition of the Nira’s Hatred mod and Helminth’s +100% Duration Invigoration, it pushed over that limit to reach 95% and even 100% damage resistance, which would make you invincible until you had lost a few stars. This was not intended and has been fixed to return it back to maintain the 90% max damage reduction.
