I have been using this weapon as one of my top-10, for the shear amount of damage numbers filling up my screen.
This is the Lazer-Minigun you have been waiting for.

-What Fire Mode?-
Primary, i dont use secondary at all.

-Where is the damage?-
1. Because the fire rate and multishot (and punchthrough) allows us to Crit often, [Hunter Munitions] triggers at a very high rate.
2. With such a large Status Chance, [Galvanized Aptitude] also reacts with [Hunter Munitions] in order to produce far more devestating damage over time.

This website states a Sustained DPS of around 72,700 (which is already pretty good), but its actually WAAAAAY higher once you take the shear amount of DoT's into that calculation. You can easily breach 750,000 DPS without Warframe powers or a riven.

-If i have a riven, what should i aim for?-
A. Crit Chance & Crit Damage would be a good replacement for Point Strike.
B. Damage/Multishot & Cold would be a good replacement for Primed Cryo Rounds.
C. Fire Rate & Multishot/CritDamage/Damage would be a good replacement for Vile Acceleration.
^ Im currently using a C-riven. 52.2% Fire-Rate - 85% Multishot - 144.4% Damage.

-Any variations?-
If you feel like Stability isnt an issue, switch [Stabilizer] for [Vigilante Supplies].
