Magnetic Might goes in the empty spot. It's not in the mod list for some reason.
I suggest you pick Fire for the innate but shock should work fine.
Galvanised Shot gives 40% per Status Effect x3 and this setup has EIGHT elements, with a 100% application rate and 20% to add 2 at a time.
Semi-Pistol Cannonade adds another 300%
Cascadia Empowered adds 6k more per shot thanks to the eight elements.

I don't usually go super high but this was doing just fine in Elite Archimedes against level 400 enemies. At 200+ it was oneshotting when hitting weakspots.
