since its an hibrid build it would hard to build it optimal until T4 gear... It starts as a int build and later goes uses might.
But that class imo is all around the DOT's, you need the cards to work it tho...
this is my thought it i were to use this build...
58 points is around lv 37 with almost all the other archertypes on lv 35.
the only cards i feel its a must are the 2 ones that causes poison on the shadow skills, and the one that removes the channelling from the holy shakles, i dont know if the card the makes and aoe zone with holy cross counts as DoT (i think it does, but i havent try it)
i left 8 free points that can be used on anything you would like.
