Build it. This weapon excels at heavy attack spam, dealing guaranteed Slash procs with its unique dagger projectiles. Its main weakness is the daggers’ inaccuracy without Xaku.
Heavy Attacks throw a horizontal spread of ethereal daggers. The first heavy attack throws 18 daggers, each with a 2.5x damage multiplier; the second heavy attack in sequence throws 9 daggers, each with a 5x damage multiplier. Daggers have a guaranteed Slash proc and innate 2 meter Punch Through.
Quassus Prime is the Primed counterpart of the Quassus warfan, offering a direct upgrade to its base version. It was released alongside Xaku Prime and Trumna Prime.
This weapon’s primary damage type is Slash, and it features innate V and Bar polarities, with a Naramon polarity in its stance slot.
The defining characteristic of the Quassus Prime is its heavy attack, which launches ethereal daggers. These daggers are considered heavy attacks, scale with combo counter and relevant mods, and inflict guaranteed Slash procs.

Builds
Given its high critical chance and multiplier on heavy attack daggers, combined with guaranteed Slash procs, a heavy attack focused build is optimal. Prioritize critical stats, heavy attack efficiency, and elemental damage to maximize the daggers’ damage output and proc potential.
