To give you some ideas (the general build concept is called 2-handed Forcewave spammer - needs high casting speed). Only belt and medal has a suffix (to show you which are good to fix the resistance hole) [edit: and weapon to show you which one could work, the ring is from your build], otherwise rather bare (means: no affixes on MI’s - no augments in armor slots, only invested the necessary skill points to make the character work, etc.)
