Looking for a propper poison bow build

hey there guys! I hope i can get a help on this post. I've been curious about the poison builds and i like bows also. I've been searching around them but im like not clear yet about it. Apparently there are 2 ways, making ele dmg to chaos and then theres a quill rain one mostly with using flat chaos dmg and such.

I'd like to know which one is better and if theres a link i'd appreciate it a lot!

Thank you and Happy playing everyone!

there are some ppl currently playing this build in this topic, try looking at their profile.

Im also playing this style, here are some recap

Pros:
-Cheap: a cheap 5L with embalmer or trying to get your 6l quill rain with under 4 ex (scouring + chance a 6l short bow from the porcupin divination card) get the first one within 40 chances but the 2nd in 3 ex value of chance and scouring.
-Almost instaleech (quill rain + thief's torment)
-Can facetank boss as long as it's not 1 shot (should have enough atk sp to sustain)
-Knock back all the time so you are safe vs melee atkers
-Good dmg, atk most bosses for 3 sec and run, they're already dead.
-ez lvling
-can easily do uberlab
Cons:
-Bad vs bosses with phase
-Rely on evasion & dodge.


Comparing between chaos & ele style (volkuur)

Chaos: cheaper, less dmg
Ele: can be very expensive bcz we need a good set of abyss jewel with atk sp life and ele dmg.

Here's an ele build and vid
