Quassus GUIDE

Understand Quassus

Useful when…

  • Normal melee with a Slash-heavy physical damage profile.
  • Charged heavy attacks that launch ethereal dagger projectiles.
  • Regular Impact slams and Blast heavy slams.

Attack modes

Normal attacks deal 27.6 Impact, 46 Puncture, and 156.4 Slash damage, with 30% critical chance, a 2× critical multiplier, and 12% status chance. The first heavy-projectile entry lists a 0.5-second charge, 46 projectile speed, 114 Slash plus 76 Puncture damage, 30% critical chance, and 1% status chance. The second lists the same charge and projectile speed, 228 Slash plus 152 Puncture damage, 30% critical chance, and 2% status chance. The entries do not specify what distinguishes the two heavy attacks. Regular slams deal 460 Impact in an area, with 50% falloff reduction by 5 m; heavy slams deal 690 Blast, with 30% reduction by 6 m. Listed range is 1.7 m and heavy wind-up is 0.5 seconds.

Projectile attacks and Xaku

Both heavy-projectile entries list a 0.5-second charge and projectile speed of 46. The description says the daggers are more accurate when wielded by Xaku, but supplies no numerical accuracy bonus. The projectile attacks are separate from the area Blast heavy slam.

Other listed melee weapons

Masseter is a Rank 8 heavy blade; its description says Grendel is immune to staggers and knockdowns during heavy attacks. Tatsu Prime is a Rank 14 two-handed nikana described as growing more powerful with each enemy’s demise, especially with Revenant. Dual Keres Prime is a Rank 14 dual-sword weapon with enhanced Heavy Attack Efficiency when wielded by Khora. These descriptions do not attribute Quassus’s projectile attacks to those weapons.

Limitations and tradeoffs

  • The first and second heavy-projectile entries have different damage and status values, but their distinguishing condition is unspecified.
  • The listed melee range is 1.7 m; the projectile attacks have a 0.5-second charge.

Common mistakes to avoid

  • Combining the two separately listed heavy-projectile entries into one attack.
  • Assuming a specific Xaku accuracy bonus.
  • Confusing the projectile attacks with the Blast heavy slam.
