CWC Covenant poison build idea

So I saw this build on poe.ninja last week some time and unfortunately it has gone missing. The idea for the build was to use The Covenant along with two Consuming Dark's to convert most fire to chaos, and then channel Incinerate to trigger Bodyswap to move around.

I'm not the greatest at making my own builds but I've taken a couple ideas and I'm trying to merge them together. For defence I feel that utilizing "While Stationary" effects sounds quite promising, that is why I have added Natural Affinity, and why I am also using Arctic Armour.

When it comes to scaling damage, I am pretty lost. I am unsure if I should try to focus on the damage over time aspect with Blackflame chaos ignite and poison, or to drop the ring in exchange for something different.

https://pastebin.com/q5bgb87x is the build link, I understand it will most likely make you throw up as it's traveling everywhere for not much, but I figured I'd just see if anyone had any suggestions on what to do/where to go.

Thanks for any assistance, Zud
