Characteristics[edit | edit source]

This weapon deals high amounts of Radiation b.png Radiation damage.


  • Fifth highest base damage of all shotguns, behind the GrineerFlakCannon.png Drakgoon, DETigris.png Tigris, SyndicateNLTigris.png Sancti Tigris, and PrimeTigris342.png Tigris Prime.
    • Innate Radiation b.png Radiation damage – effective against health.
      • Innate Radiation b.png Radiation damage gives the opposing team the ability to damage their own.
  • Projectiles have a thickness of 3 meters.
  • Good magazine size.
  • Very ammo efficient.
  • Low zoom, making covering wide shots while aiming easier.
  • Innate two Madurai Pol.svg polarity.


Notes[edit | edit source]

  • Being that it is a pulse shotgun, accuracy mods seems to have no effect on spread.
  • 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.

Trivia[edit | edit source]

  • 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".
  • The description of surviving enemies being "consumed by radiation" simply means that their bodies will disintegrate on death, making this weapon viable for stealth (if silenced).

Patch History[edit | edit source]

Hotfix 23.10.3

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

Update 23.10

  • 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

  • Tweaked force feedback sound of the Arca Plasmor.

Update 22.12

  • Mag size increased from 6 to 10

Hotfix 22.10.3

  • Fixed the Arca Plasmor dealing 0 damage on headshots.

Update 22.10

  • 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

  • Introduced.
