3.2 seeking Spark build

Howdy, hope this is the right place to ask. I was curious if anyone had been working on any sort of witch-spark build or if inquisitor is the only viable option.

If you get an Inpulsa's and a really good +1 ammy, I'd do x5 curse occultist spark

Here's a 3.1 that has OKish gear. This tree is designed for 4x curse, but the new occultist means you shoot for 5x no matter what. Modify it as you see fit to get the 5th curse. https://pastebin.com/U7CJnYN0
