Imperator Vandal build for Profit Killer Mirage: https://overframe.gg/build/157402/

This build covers IPS (Impact, Puncture, and Slash), Radiation, and Cold

Self Explanatory Build:

Mod for radiation then cold after it. Yes, radiation is covered in the Kuva Nukor Build ( https://overframe.gg/build/157419/ ), so the ImpyV will be primarily for just dealing with the Cold shield and when she has no shields at all.

DPS and fire rate are heavily exaggerated (but who doesn't love a chain-gun of death?) but essential for speedily ridding that darn Cold shield that pops up on Profit Taker

If you wanted a riven for this weapon, I would suggest something with CC/CD to add some extra oomph to the ImpyV

REMEMBER: sparingly use ammo when shooting out the cold shield, legs, and her body before swapping back to normal weapons, that will drastically keep the cooldown timer for re-deploying the archgun nice and low.
