Tenet Arca Plasmor

Semi-automatic radiation shotgun with ricocheting projectile blasts

Released Jul 6, 2021

Tenet Arca Plasmor is a primary shotgun for players who want a semi-automatic radiation projectile whose blasts stagger and ricochet. Its description says it has greater range than the classic and slower firing and reload speed; its listed attack has 18–36 meter falloff, so do not use those figures alone to infer a range comparison with the classic.

Tenet Arca Plasmor GUIDE

Understand Tenet Arca Plasmor

Useful when…

  • Consider it for projectile combat where its listed radiation damage, stagger, and ricochet behavior are useful.
  • Plan around its 10-round magazine, three-second reload, and two Madurai polarities.

How the attack works

Its Normal Attack is a projectile, fired at a listed rate of 1 per second. The attack lists projectile speed and flight as 120, with 760 Radiation damage, 22% critical chance, a 2× critical multiplier, and 34% status chance. Its falloff begins at 18 meters and reaches 50% reduction at 36 meters. The weapon description says the blasts stagger and ricochet and that surviving enemies are consumed with radiation; the attack data itself lists Radiation damage without specifying a separate consumption mechanic.

Handling and fitting

The weapon is semi-automatic, holds 10 rounds, and lists a three-second reload. Its description states that firing and reloading are slower than the Corpus classic. It has two Madurai polarities, a rank cap of 40, and a Mastery Rank requirement of 16. The description says it has greater range than the classic, but no classic falloff values are supplied here for a numeric comparison.

Related shotgun choices

The classic Arca Plasmor is listed at Mastery Rank 10 with 22% critical chance and a 1.6× multiplier. Cedo instead has a ricocheting glaive and precision buckshot, with its description tying increased damage to status effects on the target. Coda Bassocyst has an alternate fire that swarms targets not vulnerable to Mercy Kills and performs a ranged execution on vulnerable ones. These are distinct handling choices, not evidence that one is a direct upgrade over another.

Limitations and tradeoffs

  • The listed firing pace is 1 shot per second, and the description notes slower firing and reload than the classic.
  • The magazine holds 10 rounds and takes 3 seconds to reload.
  • The attack lists falloff from 18 to 36 meters.

Common mistakes to avoid

  • Treating its projectile as hitscan.
  • Assuming the classic Arca Plasmor has the same 18–36 meter falloff; no classic falloff figures are supplied.
  • Treating the description's radiation-consumption wording as a separately specified mechanic in the attack data.
