Build it. This weapon offers excellent critical stats and a unique ammo efficiency buff. Its main weakness is high recoil.
Landing a successful hit or inflicting Status damage has a 4% chance to grant 100% Ammo Efficiency for 4 seconds, refreshing on subsequent shots. It takes an Incarnon Genesis adapter from the Steel Path Circuit, which is where most of its 2026 power comes from.
The Magnus Prime is the Primed variant of the Magnus heavy pistol, offering significant improvements over its base counterpart. It boasts enhanced critical chance, critical multiplier, and status chance, alongside a slightly faster reload speed.
This weapon was released alongside Nidus Prime and Strun Prime. It also serves as a crafting component for the Akmagnus Prime, requiring two Magnus Prime pistols.
A notable feature of the Magnus Prime is its unique ‘Chamber Cascade’ buff. This passive ability grants 100% Ammo Efficiency for a short duration, which can be refreshed, making it highly ammo efficient in sustained fire.
