Chaos DOT Sorceress help

So I'm messing around on Mobalytics and wanted to see if I could make a char that is straight Chaos damage. Found the Sorcress is the best starting point for that.

I don't know much about the game, if I am honest, and would love if someone could look at this and see if it works at all. I know there's Chaos Lich builds, but I genuinely don't want to use minions.

so far it is
- chaos nodes
- some volatility
- fire because of black flame skill
- unsure if black flame implies that fire skills still burn/ignite even if they do chaos dmg.

I tried to use POB2, but voltility and ignite are not yet included
