The Magnus sports as a general-purpose version of the Sicarus, as it primarily deals Impact damage, while it deals such damage on Semi-automatic. It also comes along with greater damages on both Slash and Puncture damages, plus a decent status chance. The sacrificed characteristics are DPS, as the gun is not in Burst-fire and it spares less magazine capacity.
With a decent critical chance and damage to sport with, the Magnus can be installed with Pistol Gambit and Barrel Diffusion to further increase deliverance of critical hits on weak spots. Adding Target Cracker will deal damage up to 320%.
Though the Magnus's recoil is not too severe, Steady Hands can still prove beneficial especially at longer ranges or when firing rapidly.
While Magnus excels against shields and is moderately effective against Infested, it is somewhat disadvantaged against Corpus Crewmen and most Grineer.
