This is one of the most fun weapons in Warframe. You rapidly shoot explosive missiles! And you get a tonna slash procs! What's not to like? With this build, you can comfortably take this weapon into most content in the game.
You might replace [Serration] with Vile Acceleration, but it reduces the ammo economy of this weapon. Also, a riven should go over Serration too.
EDITS
--I swapped [Infected Clip] for [Bladed Rounds], as [Acceltra]'s 6% status chance makes modding for status mostly useless. I still kept Primed Cryo Rounds due to its large increase in base damage.
--Swapped [Terminal Velocity] for [Vigilante Supplies]
