Poison Pathfinder Build

https://maxroll.gg/poe2/planner/ha62w0zr

I am working on a poison build for my pathfinder. Your primary skill is gas arrow. You use toxic growth to apply wither and pair that with despair to debuff bosses. Plauge bearer will charge very fast while making you can use it to burst down large packs that run into your poison clouds you can also use it to apply a strong poison to vine arrow and boost its damage.

Grim feast and wind dance gives a good mix of defenses. You can add acrobatics once you have sufficient evasion to maintain around 75% - 80% evasion with it. You can add eternal youth once you get the pathfinders flask acendecy skills if you do this you may want to add alchemists boon and some other flasks nodes in the passive tree.

I am not sure of the dark entries cluster is worth it. +1 to chaos skills buffs all of our poison skills but the travel nodes to get the notable will not scale our poison. If there is a way to reach the pure chaos node or another source of added chaos damage such as Ming's Heart then the cluster may be more valuable.

Ming's Heart may provide a lot more damage but I am not sure if the reduced defenses are worth it considering how powerful Snakebite and Ryslatha's Coil are and the limited defensive stats they provide.

I am not sure what the optimal set of supports for gas arrow are either. I have seen some people removing comorbidity but I believe with pathfinder doubling poison stacks it's worth using. I have seen some people using persistence on gas arrow as well for longer poison clouds duration but I personally prefer despair to last longer.

Let me know if you have any suggestions to improve the build.
