(Update: swapped to Deadhead because of veilbreaker buffs)
(You can use secondary encumber for a more rewarding playstyle but depending a lot of rgn)

This is an very complicated gun to use, even when using [Ice Storm] or merciless... But i opted to go an high risk, high reward playstyle for the [Euphona Prime]

With no [Hornet Strike], your damage will be hard to apply... So you will have to rely on Cascadia flare's heat procs which it'll be difficult to stack and keep active because we'll be using both firemodes to make out the most of this gun

Once you activate your galvanized mods, you will have to use buckshot more to add status effects for [Galvanized Shot] and then you can go ahead and use slug shot once you got at least 2 status procs... Then it goes on

I decided to use corrosive instead of viral as this weapon falls off to kill most heavy grineer... Even thought i [Hate] not being able to use [Ice Storm] which makes this gun much easier to use
(i've decided to swap it back due to my headshots being able to kill them if status overloaded)

Corrosive or any armor strip is able to shred acolytes

For rivens, i would try getting anything that increases +reload speed or +mag capacity... But never -damage vs grineer
