PoE Storm Brand, Inquisitor, Physical builds

I've been doing some theorycrafting with the new entropic devastation gloves but i struggle to find a good synergy. Here's a scuffed inquisitor attribute CoC bow PoB (some end-game stuff), do you guys have any ideas of how to improve the build? Maybe going champion is better for fortify + impale stuff?

I think that's the way to link. Had this on my pob when checking for damage. Don't know if I changed anything since Forgot to mention staff mastery 30% inc defenses is huge. 14% life as es on chest. Leech from the cluster jewel as well as es leech from elemental mastery I believe. It ain't huge but it's still sweeeet. Since channeling can be dangerous I also said 5 hits per second like a dumbo. It's a lot more but I am too dumb to do quick maths. 20-25 balls each hitting every 0.4 seconds.
