Imbued with the finest Prisma crystal, this refined Angstrum features boosted charge and reload speeds.

The Prisma Angstrum is the Prisma variant of the Corpus-built rocket pistol Angstrum.png Angstrum, featuring slightly higher critical chance, critical multiplier, and faster charge-up and reload speed.


  • This weapon deals DmgBlastSmall64.png Blast damage.
  • Rocket explode in a 3.6 meter radius on impact with a surface or enemy.
    • Initial hit and explosion apply status separately.
    • Explosion does not need direct line of sight to deal damage and will penetrate walls.
    • Explosion inflicts self-stagger.
    • Explosion has linear damage falloff from 100% to 60% from central impact.
    • Can benefit from Mod TT 20px.png Fulmination (Mod TT 20px.png Primed).
  • Can be charged to unload more of the weapon's magazine and fire extra projectiles.
    • Can be fired with a partial charge to fire only part of its magazine.
    • Charged barrage spreads rockets out, reducing the effective range considerably.
    • Multishot will cause partially-charged shots to spread out further, eliminating its long range potential.
    • Fully charged shot consumes the entire magazine, even when magazine mods are used.
  • Innate Vazarin Pol.svg polarity.


  • Tied with normal Angstrum.png Angstrum for highest base damage of all secondaries.
  • High accuracy.
  • Very fast charge speed.
  • Single Rocket Impact
    • High damage
    • Above average status chance
    • Above average crit multiplier
  • Single Rocket Explosion

  • Projectiles have travel time, slow speed, and are small, making long range shots difficult.
  • Very high recoil.
  • The weapon fires as soon as it has reached a full charge, which can lead to premature firing.
  • Extremely poor ammo efficiency
  • Extremely low magazine size of 3 rounds; requires frequent reloading.
  • Very low ammo capacity of 18 rounds.
  • Rockets have a short delay after firing before being able to fire again.
  • Enemies can destroy the rockets with gunfire or area of effect explosions.

The Prisma Angstrum can be sold by Baro Ki'Teer in the Concourse section of the Tenno Relay for Credits64.png 210,000 and PrimeBucks.png 475. Note that Baro Ki'Teer's stock changes with each appearance, and this weapon may not be available on a succeeding appearance.

The weapon can be traded, but only for unranked copies without Forma and Orokin Catalyst installed. The trading recipient must also have a Mastery Rank of at least 8.


  • The UI damage value of 1350 refers to the total impact and explosion damage from all three rockets.
  • The Prisma Angstrum's extremely fast charge rate before firing a full rocket swarm can allow players to eschew fire rate mods that would otherwise be needed on the normal variant, allowing for better damage-based builds.
  • Synergizing with Mirage's HallOfMirrors130xDark.png Hall Of Mirrors, the Angstrum with lowered accuracy can fire in a very large area of effect.
  • There is a slight yet noticeable delay between the Angstrum completing its charge and the rockets exiting the barrel.


  • The Prisma Angstrum is the first Prisma secondary ever released.


Patch History[]

Hotfix 27.2.2 (2020-03-06)
Reduced the following AoE weapons Radial Damage Falloff from central impact that were all previously 90%:

  • Prisma Angstrum: 40%

Update 27.2 (2020-03-05)

Self Damage Changes

We are getting rid of Self Damage and replacing it with something else: instead of Self Damage, it’s now ‘Stagger’. This change completely removes the chance of killing yourself, and instead now creates scenarios where you will interrupt yourself - or ‘Stagger’ - to varying degrees if you aren’t careful.

The degrees of Self-Interrupt start with a small stumble all the way to full knockdown depending on how close you are to the center of explosion. Any Mods referring to Self Damage will be converted to acknowledge Stagger.

With this Self-Interrupt system, we have added dozens of new recovery animations that harness a ninja-like recovery experience. By pressing ‘Jump’ at the correct time, you can execute a ninja-skill-based knockdown recovery to ALL in-game knockdowns. This ninja recovery window is indicated by a glowing FX on your Warframe.

In the original Dev Workshop, we said:
As a result of this overall systemic change, Weapons with Stagger will be getting approximately a 20% buff in Damage, with any weapons with AOE receiving a 50% Radial Damage Falloff from central impact.

This is no longer accurate after continued testing. What we are doing now is:

No damage buffs have been added, but any weapons with AOE are receiving ~20% increase in Radius. Additionally, AOE weapons are receiving a 90% Radial Damage Falloff from central impact. This means on the very outer section of the explosion Radius 10% of the Damage will be dealt. Tactics will be deadly - aim true, Tenno.

Why: Several players brought up the history of the Tonkor and we want to make sure we ship this change in a place that’s conservative in its starting point from a balance perspective. The complete removal of Self Damage does change the pace of destruction with some of the game’s most powerful weapons, so we want to make sure we can iterate upwardly instead of releasing a bonanza of explosions with no other choices.

Greater than 100% Status having meaning

Shotguns have a unique Role here based on a very patch-work history with how they interact with Status Chance. A Shotgun that shoots 99% Status Chance would give you 35% (roughly) status per pellet. 100% Status Gives you 100% Status per pellet. This huge jump in performance happens with just a 1% gain - why? Well, to answer that we have to look at our choice to make what the UI conveys reality. It would feel broken to shoot a Shotgun with 100% Status and not see a perfect spread of Effects. In reality, to make Status consistent we have to treat Shotguns as a special case.

Shotguns as a special case means we have buffed the Status Chance of all Shotguns by x3 or greater. The UI now behaves to show the reality that you are determining Status Chance per pellet.
