PoE One_Kaleidoscope_271, Physical builds

Helo guys, earlier i made a post requesting some builds and i decided to put together a variation of cast while channeling. Just a regular CWC with EK but based on poison, IF someone can give me ideas. &x200B; The main gripe is mana sustain and how to make poions last longer. More HP pool would hel a lot too. &x200B; A Chain source would do wonders i think, but i cant think of one atm
