But don't worry, the admin and editor team are aware of them and they will be resolved over the next few days as our Weapons Module goes through a much needed overhaul.
Sorry for any inconvenience!

Flick away the enemy with this heavy warfan. The Quassus scatters ethereal daggers that are even more deadly accurate when wielded by Xaku.

The Quassus is Xaku's signature warfan, possessing high damage and critical chance along with throwing ethereal daggers from Heavy Attacks that proc DmgSlashSmall64.png Slash, with these daggers being more accurate in Xaku's hands.


  • This weapon deals primarily DmgSlashSmall64.png Slash damage.
  • Heavy Attacks throws ethereal daggers, with each dagger doing 76 base damage.
    • The first heavy attack throws 12 daggers, each with a 2.5x damage multiplier; the second heavy attack in sequence throws 6 daggers, each with a 5x damage multiplier,
    • Damage of the daggers are affected by mods.
    • Daggers are considered a heavy attack. Their damage will scale from the combo counter and mods such as Mod TT 20px.png Killing Blow.
    • Daggers have a guaranteed DmgSlashSmall64.png Slash proc.
    • Daggers have innate 2.5 meter Punch Through.
    • Dagger damage does not diminish with distance.
    • Have travel time.
    • Have a limited range of ~35 meters.
    • Cannot use Thrown Melee mods Mod TT 20px.png Combo Fury, Mod TT 20px.png Power Throw, Mod TT 20px.png Quick Return (Mod TT 20px.png Volatile), Mod TT 20px.png Rebound (Mod TT 20px.png Volatile), and Mod TT 20px.png Whirlwind.
    • Multiple projectile hits from one attack against a single enemy may occasionally get merged into a single "instance" of the attack and Bleed proc, reducing the effectiveness of per-hit mods like Mod TT 20px.png Relentless Combination.

Patch History[]

Update 29.5 (2020-11-19)

  • Fixed the Quassus and Gunsen gaining different Melee combo counters on first hit with the Slicing Feathers Stance. They will both have the same 3 combo counter hits now.

Hotfix 29.2.1 (2020-10-01)

  • Fixed the Quassus leaving you "unarmed" after using heavy attacks.

Hotfix 29.1.1 (2020-09-18)

  • Fixed issue that stopped Pressure Point and its derivatives from not applying to Quassus Heavy Attack projectiles.

Hotfix 29.0.8 (2020-09-10)

  • Increased Heavy Attack projectiles from 35 to 76
    • Also fixed Quassus Heavy Attack projectiles being slowed down to 15% of their original speed after punching through an enemy.
  • Reduced horizontal spread of projectiles
    • Quassus throws 12 projectiles with a pretty wide horizontal spread, spreading the Damage across multiple targets. Individual damage was not where we wanted it. Increasing it over 100%, narrowing the spread and making sure it will hit additional targets after passing through, increases its lethality to intended levels.

Hotfix 29.0.2 (2020-08-26)

  • Fixed a crash when inspecting the Quassus’ stats in the Mission Progress screen while in the Cambion Drift.

Update 29.0 (2020-08-25)

  • Introduced.
