I think the new helm got magic damage boost.
The ring with magic damage boost and fcr.
The belt with 20fcr and frw is great i guess.
DR% will be hard on such a build, so sometimes you want dungo, other times you want coa or BER BER diadem.
The new jewel boost magic damage.
Sometimes a hybrid can be fun.
You can build them like before, but there exist more items now to boost your magic damage as well as there are boots which adds magic res.
So to counter theese new boost you need to have -30% enemy magic res i think.
