Notes
- The UI damage value of 1350 refers to the total impact and explosion damage from all three rockets.
- In other words, the damage that is shown in the Arsenal refers to the total damage that can be dealt from a single magazine.
- If you increase the magazine size, the damage would also increase.
- In other words, the damage that is shown in the Arsenal refers to the total damage that can be dealt from a single magazine.
- The UI status chance value of 52.5% refers to the status chance from all three rockets. The actual status chance per rocket is 22%.
- Tapping the fire button will let out a single, very accurate rocket which can be used to pick off targets from long or medium range; or be held halfway or fully to release half or the entire magazine respectively, which will cause a wide spread of rockets to cover large groups at closer ranges.
- The Angstrum must reach a given level of charge in order to fire a single shot or volley. Use Fire Rate mods such as Gunslinger to reduce the time required to charge.
- Use the reload button or change weapon to cancel charge to avoid unwanted shots.
- Keep in mind that Multishot will eliminate the dead-on accuracy of the single shot, as it will cause 2 or 3 rockets to skew outwards, with none of the rockets going right where the reticle is.
- The Angstrum's charge cannot be held. The weapon fires as soon as it is fully charged.
- Constantly tapping the fire button will not cause this weapon to stall like the Ogris. If you accidentally begin charging the weapon, without meaning to, you can stop the shot simply by spamming your charge button and hitting reload while you prevent the weapon from releasing a rocket.
- There is a delay between pressing the fire button, and the rocket actually being ejected. pressing the fire button again before it is ejected will cancel the ejection-jamming like the Ogris.
- Unlike a shotgun which shoots a completely random spread, the Angstrum is shown to form a geometrical structure (depending on the grenade quantity) of:
- One - A single accurate shot.
- Two - Two separate horizontal shots.
- Three - A triangle.
- Four - Diagonal square.
- Five - Pentagon.
- Six - Triangle with an offset center triangle.
- Seven - Diagonal square with a center triangle.
- Eight - Pentagon with an offset center triangle.
- Nine - Hexagon with a center triangle.
- Ten - Heptagon with a center triangle.
- Eleven - Octagon with a center triangle
- Twelve - Outer diagonal square, middle pentagon, center triangle
- Thirteen - Outer pentagon, middle pentagon, center triangle
- Fourteen - Outer hexagon, middle pentagon, center triangle
- Fifteen - Outer heptagon, middle pentagon, center triangle
- Sixteen - Outer octagon, middle pentagon, center triangle
- Seventeen - Outer enneagon, middle pentagon, center triangle
- Eighteen - Outer decagon, middle pentagon, center triangle
- Nineteen - Outer hendecagon, middle pentagon, center triangle
- Twenty - Outer dodecagon, middle pentagon, center triangle
- Angstrum's shots bounce off Nullifiers' barriers rather than exploding, and will detonate upon hitting another solid object. Beware as this includes the player who fired it.
Tips
- Use Magnum Force if you wish to cover a greater area, as the damage bonus granted by this mod can help counteract any loss of damage due to the accuracy penalty. Bear in mind this is at the expense of the Angstrum's charged shots at long range.
- Fulmination can also be used to fill a target area more completely as the increased blast radius provided by it will counteract the empty spaces in between spread out charged shots.
- To more accurately hit a group of targets, Bullet Jump straight up and aim glide at the targeted area and then fully charging up your shot so all of the individual rockets will connect and explode on contact with the ground. This way, the explosion will do much more damage spread out over a consistent area rather than just shooting on the floor.
- If charged and/or a Multishot mod is equipped ( Barrel Diffusion, Lethal Torrent), the rockets will fire in a precise shape based on how many rockets are fired, making it easier to aim.
- Increasing the magazine size will result in a higher projectile count when firing a totally charged shot. Bear in mind that increasing the magazine size will also increase the time it takes to charge the shot.
- Using Slip Magazine, Ice Storm, and Tainted Clip will increase the Angstrum's magazine to 7 (rounded from 6.9).
- With Primed Slip Magazine, it can reach 8 rockets
- With
- Combining the magazine build with Barrel Diffusion and/or Lethal Torrent will yield the chance of a totally charged shot firing 21 projectiles.
- With the above primed mod, it can reach 24.
- Using the previous combination with Mirage's "Hall Of Mirrors" wasn't found in Module:Ability/data can yield a total of 63 projectiles in one salvo. This is obviously not recommended for low configs.
- Can reach 72 if chances play out.
- Using
- Gunslinger and/or Lethal Torrent speeds up the charge time, allowing for faster firing rates. This is especially important if one is maximizing magazine capacity, as the charge time for a large magazine can be long.
- Mag's Magnetize synergizes well with this weapon, as it allows all the rockets fired to be redirected unto a single target, dealing massive amounts of damage. This is most useful against heavy units like Napalms, and against bosses that have no weak spots like Ambulas.
- It is highly recommended to equip a Pistol Ammo Mutation mod to remove practically all ammunition problems.
- Lethal Momentum can increase rocket velocity by up to 40%, significantly reducing the amount of lead time required for distant targets.
- The innate Script error: The function "Pol" does not exist. polarity can somewhat limit elemental modding potential, thus making it a less desirable polarity for elemental modding. If you wish to focus more on elemental damage, then it is recommended to either ignore the polarity or use Forma to turn it into a more suitable polarity.
- Putting Deep Freeze and making use of the secondary elemental damages that use Cold damage can make use of this polarity.

Trivia
- The Angstrum's name is derived from Angstrom, which is a unit of measurement that is 0.1 nanometers in length.
- This weapon appears to be of Corpus design, making it their second explosive weapon following the Penta.
- When charging, the rockets in the chamber lower into the gun itself.
- The Angstrum's concept of a conventional-appearing weapon (pistol in this case) firing rockets is similar to that of the Gyrojet from the 1960s.
- Its boxy design is similar to the IMI Uzi MP-2 machine pistol, including the way the weapon can be held.

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%:
- 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.
