No, for pet wd helm should be Mask of Jeram and nothing else if you want to be effective. If you want to have full zuni set, then it's probably better if you go for boots + chest + mojo. Since you won't be in the middle of the fight, damage reduction is not that crucial as it is for jade build.
Is that Mask of Jeram supposed to show a static +75% pet dmg? Or is that new to 2.1 and Blizz just let it slip in the game guide w/o telling anyone?
For Jade:
Belt: Hwoj Wrap for survival, Harrington/Witching Hour for damage
Offhand: Uhkapian serves incredible survival.
Your elemental damage should always aim for cold damage as it's the main damage resource of Jade.
A strong weapon means a slow & strong 1H weapon and it's Sunkeeper.
How "mandatory" is +cold dmg for Jade doctors? I have 5 pieces and am thinking of farming for a RoRG. But I have no +cold dmg gear (except the crafted lego axe) and am not sure I want to farm for the new items/enchant mats. I know the DoT skills are cold-based, but...
