PoE ShayaanKiani builds

Hey I tried pob a high budget tanky rf elementalist. Crit immune, 90 max res, capped chaos res with fourth vow, curse immune, edurance charges, 190 movement speed and still around 13 mil dps. Not sure if there are better ways to scale defences fourth vow seemed like a decent option. POBB:

Had an idea for a tornado shot impale champion that uses steelworm alongside perseverance to scale defences. Getting damage on the build is the tricky part, has anybody played any impale builds and have some ideas on how this can be improved?
