Tier 6 firestarter chem build

I have a question and maybe seeking advice/ or help.

I have tier 6 fire chem build with the capacitor build. upon fire chem and chem activation im ticking about 335K per tick before any dmg buffs start to apply. I have eclipse build as the basic but want to know what the absolute highest damage and tick numbers I can achieve. I really like this build but don't know what else to do to get it at max potential. highest tick ive done is about a little over 550K. who can help?
