Gameplay Help and Discussion - Incredibly nooby and probably stupid questions about poison arrow - Forum

I really want to make a poison arrow build, but I have some questions..

Because I want PA to be my main skill, should I still take +projectile damage and +bow damage passives? Or just stick to health and the +chaos/dot passives? I'm just not sure if they will do much for me if my main skill is chaos damage.

Would anyone be willing to throw together an example passive tree I could look at? Just for some ideas on how to build? I will be playing on rampage.

Is there a point to hitting the same mob twice with PA? Does it increase the duration of the DoT? Or should I just throw down a PA cloud and attack with something else while the mobs are dotted?

I'm not sure if this is just lag or something else, but it seems like if I don't actually hit the mob with PA, they don't seem to take any damage from just walking through the poison cloud on the ground.. am I missing something or is that the way it is?

Will I be able to do maps?
