Poison Plant Build

So I have this idea for using plant spells for poison/chaos damage. And so far during the campaign it seems fine, but I’m mildly concerned about T15+ maps. My theory so far is to avoid crit damage and go hard into poison magnitude/%increased chaos damage. Because cheaper, I think. Also, I was thinking about adding bleeding.

My core gems for entangle would be: poison 3, bleed 3c admixture, branching fissure 2, and zennith 2. Currently 8/8 lich haven’t done abyssal convert yet
