Capable of firing multiple rockets at once, the Angstrum is a handheld instrument of destruction.
The Angstrum is a heavy pistol of Corpus design that fires tiny but powerful rockets. Its charge-based trigger allows for firing precise single shots, or emptying the entire magazine as a spread barrage for engaging single heavy targets or large groups. It was released in Update 13.3.0.
Use Magnum Force if you wish to cover a greater area (as there is no secondary counterpart for Firestorm), 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.
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.
Combining the magazine build with Barrel Diffusion and/or Lethal Torrent will yield the chance of a totally charged shot firing 21 projectiles.
Using the previous combination with Mirage's Hall of Mirrors can yield a total of 105 projectiles in one salvo. This is obviously not recommended for low configs.
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 Bullet Attractor 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.
Since the Angstrum shares ammo capacity with a primary that also draws from the sniper pool, a Sniper Ammo Mutation on the primary will also benefit the Angstrum.
Lethal Momentum can increase rocket velocity by up to 40%, significantly reducing the amount of lead time required for distant targets.
The innate 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.
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 clip 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 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 reticule 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 - Hexagon.
Seven - Hexagon with a center point.
Eight - Pentagon with a center triangle.
Nine - Hexagon with a center triangle.
Unlike other explosive weapons in the game, the Angstrum does not have 2 damages: the impact with the enemy and the AoE explosion. Instead, the rockets simply explode and deal only AoE damage.
This means that any elemental damage is also dealt in an AoE.
