Arca Plasmor

Semi-auto radiation projectile shotgun

Released Sep 9, 2017

Arca Plasmor fires a slow, hard-hitting radiation projectile that staggers targets. Consider it when you want a deliberate shotgun blast with an area component, and can manage its limited magazine and projectile travel.

Arca Plasmor GUIDE

Understand Arca Plasmor

Useful when…

  • Firing into groups or close engagements where its projectile and nearby explosion can matter.
  • Using a shotgun with innate radiation damage and a listed 28% status chance.

Projectile and blast behavior

Its normal attack is a projectile traveling at a listed speed of 60. The attack lists 600 Radiation damage, 22% critical chance, a 1.6× critical multiplier, and 28% status chance. The weapon description says blasts stagger targets. It fires semi-automatically at 1.1 attacks per second.

Practical use and upgrades

The 10-round magazine and 2.8-second reload reward deliberate shots and reloading during a safe pause. Its two listed Madurai polarities are relevant when planning compatible mod slots. Critical chance is moderate at 22% and the multiplier is 1.6×; consider upgrades in light of those base values and the 28% status chance rather than assuming a bonus produces a particular final damage. The weapon requires Mastery Rank 10.

Related shotguns

Tenet Arca Plasmor retains staggering radiation blasts, with its description adding ricochets and greater range alongside slower firing and reloading. Coda Bassocyst is described with a different alternate-fire interaction tied to Mercy vulnerability. Corinth offers a separate choice between a shotgun blast and an alternate projectile that explodes mid-air and knocks down nearby enemies. These descriptions identify distinct mechanics; they do not establish that any one is a better fit for every player.

Limitations and tradeoffs

  • The projectile has listed falloff and travel speed, so firing and positioning differ from an instant hitscan shot.
  • The 10-round magazine, 1.1 fire rate, and 2.8-second reload limit sustained output.

Common mistakes to avoid

  • Treating the projectile as hitscan; it travels and has listed damage falloff.
  • Ignoring the long reload when firing through the entire 10-round magazine.
