Built in the image of the lifeless corpse-moon that orbits Doisac, with secrets that only the most cunning Jiralhanae can unlock. Advanced Brute Plasma Rifle with increased damage, but can also serve as an utterly lethal melee bludgeon.
— In-game description[1]

Scale of Soirapt is a variant of the Type-25 Brute Plasma Rifle that was released in the Warzone Firefight content update for Halo 5: Guardians.



The Scale of Soirapt is a Ultra Rare-tier REQ available at level 4 energy. It is similar to the normal plasma rifle but it has more damage and can be used like a bayonet to instantly kill a spartan in the war games. Use this to either drain shields at afar then use a ballistic weapon to drain the spartan's health.

Changes from the Jiralhanae Plasma RifleEdit

  • Increased damage.
  • Melee attacks with this weapon kill in one hit and produce a flash on impact.


  • Soirapt is one of three natural satellites orbiting Doisac, the Jiralhanae's homeworld.
