Coc Bow Trickster with poison?

Hi,

Im theory crafting for days now trying to find the perfect build to start a trickster on budget.

i have a few questions about the viability of my current plan.

First question: got a bow with lvl 18 coc, 8,65 Crit chance,
1.2 attks per sec, 26 crit and 50% if crit recently,
arrows pierce 2 targets, and 26% poison dmg.
Is this bow any good?


Second question
I found a build from the character: Lordie,

Its also a coc build wich uses essence drain, contagion and wither(totem)

with toxic rain to proc the drain.

Im planning to use poison in it(first cause the Fenumur helm gives chance to give power charge on hit on mobs with aspect of spider, second to use an agony crawler if i get a 5-6 linked chest.


Essence drain hit for about 600 basic flat chaos dmg per hit. Can i build poison around this? Or should i just focus on chaos dmg only?



Wonder if anyone has an answer for my very spesific question.

Thanks!
