Poison is the best choice for pve, swap all your elements on poison
U need this affixs:
Plagued (set affix)
+2 all sets (nadroji ring, or mythstone +2 all sets)
An axe for first time a good, on it there is blight (if u swap element on poison), and nice wpd.
The amulet is good, but then if you need a place to affix, remove all skills and all talents, NOT SET NUMBERS.
Helm nice, just change affixs
Look through the code, there you will find plagued and drudic items, there you will find something to complement your build
