Key to this build is Cascadia Empowered. It will add the damage to this build (750 per status effect on rank 5, one shot triggers about 15-20 status effects, even more once [Galvanized Diffusion] stacks are build up). This is currently not shown in the numbers here on overframe.

I use this with Yarelli (build for strength and duration) in combination with her Aquablades, which add slash procs and inrease damage even more. Arcane Velocity for additional fire rate also helps to increase DPS. Yarelli's passive and the multishot will trigger the arcane despite the low crit chance.

Feel free to change the elements as needed.

This build works for me and my playstyle. Works on steel path (< lvl150)
