GENERAL
This weapon is interesting. It got so low of base CC but the base status is pretty high. I've tried using full status build without any critical related and it is still really strong (I tried against level 120 Corrupted Heavy Gunner). Also, the base elemental damage is Corrosive, so you can build this weapon with 3 combo elemental: Corrosive, Viral, Heat. The fact that the status is so high it can strip armor so easily since you can get those 3 elemental combo proc at the same time.

WEAPON FUNCTIONALITY
This weapon got a kinda trash fire rate and projectile speed, putting fire rate mod will gives a big impact in terms of DPS and since you don't have to put critical mods you got some spared slots and putting some fire rate will be a great idea. The weapon itself will explode upon contact so with this you can go for [Heavy Caliber] for more damage without worrying about weapon accuracy. Exilus mods can be anything, can be put with [Terminal Velocity] to increases the projectile flight speed.
