CODEX

Stagger targets with blasts from this Corpus engineered plasma shotgun. Surviving enemies are consumed with radiation.

The Arca Plasmor is a Corpus-built plasma shotgun that fires highly damaging pulses of with a guaranteed proc. The projectiles it fires have high status chance, large thickness, and innate 3 meters Punch Through against bodies, making it highly effective in mowing down large groups of enemies, but suffers from a low critical multiplier and no bonus damage on headshots. It can be researched from the Energy Lab in the dojo.

Characteristics

This weapon deals high amounts of damage.

Advantages:

• Innate damage – effective against Alloy Armor, Robotic, and Infested Sinew.
• High critical chance.
• Very high status chance.
  • Innate confuses enemies and makes them indiscriminately attack each other.
• Shots have a guaranteed proc to enemies up to 15 meters.
• Projectiles have a thickness of 3 meters.
• Innate 3 meter Punch Through against bodies.
• Good magazine size.
• Very ammo efficient.
• Low zoom, making covering wide shots while aiming easier.
• Killed enemies will have their corpses vaporized, good for Stealth gameplay if silenced due to no bodies being left behind.
• Two innate polarities.

Disadvantages:

• Innate damage – less effective against Shielded, Infested, and Fossilized.
  • Damage cannot be increased with , , and mods.
• Has linear damage falloff from 100% to 33.33% from 10m to 20m target distance (distances are affected by projectile flight speed).
• Projectile has travel time.
• Limited range of 30 meters (can be increased with projectile flight speed mods).
• Low critical multiplier.
• No bonus damage on headshots.
• Very low reload speed.
• Lowest fire rate of all shotguns.
• Innate Punch Through does not apply to surfaces if hitting with the central portion of the projectile, requiring Punch through mods.
• Enemies defeated with this weapon disintegrate quickly, making it ill-suited to use alongside  Nekros'  Desecrate.

Notes

• Being that it is a pulse shotgun, accuracy mods seem to have no effect on spread.
  •  Vicious Spread however throws off accuracy by making shots veer wildly off from the aiming reticle at times, use at your own discretion.
    • This can be counteracted somewhat with  Hell's Chamber, which will cause the weapon to fire 2-3 waves of energy.
    • Vicious Spread can also be counteracted by using Mirages' ability, do note that projectiles fired by the clones bounce off solid surfaces instead of dissipating.
    • A possible bug,  Tainted Shell does not counteract Vicious Spread's accuracy decrease in any reasonable measure. Meaning that if you install both, the accuracy will still be significantly lower.
• The Plasmor's pulse has a range of 30m. This scales with projectile flight speed mods, including the  Jet Stream augment.
• Shots will only proc if the target is within 15m.
• The Plasmor has a reduced zoom by about 60% when aiming.
• While the weapon uses shotgun mods and it is classed as a shotgun, it does not use standard shotgun status mechanics, due to not having any pellets. This means the status is much more reliable per shot.
• While the critical chance of the weapon is good, the critical damage is only slightly better than normal.

Tips

• Can reach over 100% status chance:
  •  Shotgun Savvy and  Nano-Applicator combined with three of  Scattering Inferno,  Frigid Blast,  Shell Shock, or  Toxic Barrage.
  •  Shotgun Savvy or  Nano-Applicator combined with four of  Scattering Inferno,  Frigid Blast,  Shell Shock, or  Toxic Barrage.
• Due to its high inherent punch-through, the Plasmor is of great use in Arbitrations, easily passing through shielded enemies to get to shield drones.
• Because the range and damage falloff are determined by the weapon's projectile flight speed, adding in  Fatal Acceleration will increase the range and falloff limits by 40%, to 14m minimum falloff and 28m maximum falloff as well as increasing the range to 42m.
• Due to its innate damage, the weapon can use elementals and dual elementals that use or damage, such as VS Grineer or VS Corpus.
• Consistent procs from the weapon at medium range or less may negate the need for damage for crowd control, allowing the player to use damage instead which slows enemies and extends the Impact stun duration.
  • This also allows the weapon to have the advantages (and disadvantages) Cold damage brings.
• Short corridors favor this weapon highly, as a few pulses are normally enough to make short work of enemy clusters as long as no Arctic Eximus or Nullifier Crewmen are present, and the added Impact and Radiation procs will keep enemies at bay.
  • Applying  Seeking Force and  Seeking Fury will increase the lethality of the weapon to copious amounts, increasing survival chances against deadly skirmishes.
• The description of surviving enemies being "consumed by radiation" simply means that their bodies will disintegrate on death. While this is undesirable for a Nekros's  Desecrate, it is good for stealth if silenced since there will be no corpses to alert enemies.

Trivia

• The magazine for the weapon is a metal cylinder, which rotates clockwise after firing each shot and pumping the mechanism. No shells are ejected with each pump, perhaps implying the cylinder is filled with batteries or charge cells, which are depleted from a single pump and must be rotated to bring a new cell into position.
• Writings on the side of the weapon seem to translate as "G.S.1.1", and possibly "DANGER EXTREME HEAT".

Patch History

Update 25.8 (2019-10-01)

October 2019 Riven Disposition Change

• Arca Plasmor: 0.6->0.55

Hotfix 25.7.5 (2019-09-09)

• Fixed Arca Plasmor not being able to damage the Ropalolyst Synovia.

Update 25.7 (2019-08-29)

• Reduced the light intensity of the Arca Plasmor.

Hotfix 25.0.3 (2019-05-24)

• Fixed an issue that made Arca Plasmor, Fulmin and Catchmoon projectiles deal damage twice on the hit when the projectile is destroyed. This was not a case of ‘always worked this way’ as it was accidentally introduced by the Jovian Concord.

Update 24.6 (2019-04-04)

• Improved the left hand position for Arca Plasmor.

Update 24.0 (2018-11-08)
The previous Mainline update of Chimera 23.10.0 included a sneaky bug that removed falloff damage from the Arca Plasmor. The Arsenal continued to state the always present falloff (10.0 - 20.0) but it wasn’t truly applying. We have fixed this bug, which resulted in adding falloff damage back to the Arca Plasmor, and thus returned it to its original falloff state prior to Update 23.10.0. This also fixes the Conclave Arsenal displaying the incorrect falloff damage for the Arca Plasmor.

Hotfix 23.10.3 (2018-10-15)

• Fixed the Arca Plasmor's projectiles bouncing off walls instead of exploding on impact.

Update 23.10 (2018-10-12)

• Updated weapon FX for the Arca Plasmor, Castanas, and Sancti Castanas.
• Fixed certain wave projectiles (e.g. Arca Plasmor) bouncing off hit proxy shields (e.g. Volt’s Electric Shield, Gara’s Mass Vitrify).
• (Undocumented) Projectile now bounces off walls.

Update 22.14 (2018-03-01)

• Tweaked force feedback sound of the Arca Plasmor.

Update 22.12 (2018-02-09)

• Mag size increased from 6 to 10.

Hotfix 22.10.3 (2018-01-29)

• Fixed the Arca Plasmor dealing 0 damage on headshots.

Update 22.10 (2018-01-25)

• Headshots no longer deal bonus damage.
  • The Arca Plasmor was designed to hit multiple targets with a high-status chance, but with wide wave projectiles and inherent punch-through, a single shot could result in multiple headshots. With it being a shotgun, it was never intended to behave as a precision weapon, and the bonus pushed it too far out of that mold.
  • Headshots should still deal damage (without the multiplier).

Update 21.7 (2017-09-09)

• Introduced.

Last updated: Update 24.0 (2018-11-08)
