Quassus Prime GUIDE

Understand Quassus Prime

Useful when…

  • Use its normal attack for a Slash-weighted melee damage profile.
  • Consider the two heavy dagger projectile attacks as separate charged attacks.
  • Use regular and heavy slams for their distinct area damage profiles.

Normal attack

The normal attack deals 26 Impact, 52 Puncture, and 182 Slash damage. It has 35% critical chance, a 2.5× critical multiplier, and 18% status chance, with listed attack speed of 0.833. Listed handling includes 1.7 range, 0.7 follow-through, a five-second combo duration, and a 55-degree blocking angle; the range unit is unspecified.

Heavy dagger projectiles

The first and second Ethereal Daggers attacks are distinct projectile profiles. Each has a 0.5-second charge time and attack speed of 2; projectile shot speed and flight are each listed as 46, with units unspecified. The first deals 114 Slash and 76 Puncture damage with 1% status chance. The second deals 228 Slash and 152 Puncture damage with 2% status chance. Both list 35% critical chance and a 2.5× critical multiplier.

Slam attacks

The regular Slam Attack deals 520 Impact damage with 10% status chance; its listed falloff runs from 0 to 5 with a 50% reduction. The Heavy Slam Attack deals 780 Blast damage with 34% status chance; its falloff runs from 0 to 6 with a 30% reduction. Units for these falloff values are unspecified.

Limitations and tradeoffs

  • Normal, projectile, and slam attacks have different damage and status profiles.
  • The listed range and falloff values have no specified units.

Common mistakes to avoid

  • Treating the two heavy dagger entries as one attack profile.
  • Applying the normal attack’s status chance to the projectiles or slams.
  • Assigning units to the listed range or falloff values.
