PoE builds similar to POE-Triggering 10800 skills a minute (Cold version)

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.

Here is my unoptimized POB, need to balance cost reduction currently cause inspiration is a dead link, need to have exactly 1 mana cost: I started this build because in theory Bodyswap is the best movement skill in the game since it has no cooldown and auto targets. It just has hard to scale damage (life stacking is a trap imo), and you need a lot of cast speed to make it feel good. Soulthirst + Ignite solves those issues and has respectable dps. For a non-meme version use auto flasks (20+ second flask duration is fine) and stack mo

Added wave of conviction for Fire exposure, since pob doesnt see i have fire exposure on gloves. I have level 91 Corpse on Unearth, i dont know how much life corpses have, i see many debates on internet. So i put a midle ground there 200k, maybe its more maybe its less. What i know is, it does a lot of damage. The only mana i need is 65 mana for flammability, more would be a waste, less would be a waste of damage. ( was thinking the second curse for Elemental weakness curse, would be a good damage boost on bosses only).
