I have just an idea that i like to share.
A/P
shadow arts: 12 (10 +1 +1)
spear mastery: 10
critical strike's: what's left
skills:
Barbed spear
might throw
seeping wound (E)
wild throw
shadow refuge
critical eye
res sig
a whatever skill
Maybe you guys can work it out further.

actually, this sounds like a great idea for a build, but it needs some adjusting. make sure that critical strikes is at 13 so seeping wound does -4 degen. definatley raise spear mastery to 12. take out critical eye and add caltrops or feigned neutrality and for the last skill use dark escape/dash. you dont need such high shadow arts, so lower that to 9-10. if its possible, take out caltrops/feigned neutrality and get some blocking skill in there like maybe critical defenses.

You'd want 12 spear mastery, at least 13 critical strikes and the rest in shadow mastery.

Well, i'm using my own build for a while. I changed it like 15 time's But you do verry nice damage with the build. I use Eshau's Spear (you can gaing it in the beginning outside Yoholon Haven) My highest strike is with might throw of 149 damage. The build kills verry fast and from distance what is verry easy. Your idea of neutrality feing and dark escape is great. You can rush away when you are losing
