This build is based on the one given by GrindHardSquad in his video The Most Powerful Guns You Can Craft In Warframe Right Now. It's main focus on proccing as many slash effects as possible. You can swap around the Bane mod as necessary.

I changed the Deadhead arcane for Merciless as I prefer the reload and ammo bonus.

I switched the Pax [Seeker] with Residual Shock and combined it with a Theorem Demulcent on my warframe. The theorem gives another 180% extra damage when at max stacks. I choose Shock as it gives me another element type for [Galvanized Aptitude] to work with. But, you can switch to any of the residuals according to your personal preference. I just like seeing my enemies getting electrocuted.
