Immunity from Crowd Control

My build is Grace of Inarius with Ring of Royal Grandeur with Necromancer. I sometimes get killed, even with Final Service passive skill, in an explosion when I get drawn into it forcibly. Invigorating Gemstone or Krelm’s Buff Bracers would give me immunity and when I play Rift, transporting is also a lot easier with the immunity. But Nemesys Bracers and Bane of the Trapped gemstone seem irreplaceable in my build. Any suggestions?

Does Necromancer have a Wrath of the Berserker (barb) or Vengeance (DH) type skill? If so, reduce its cooldown so you can keep it going constantly. Being in that state usually includes immunity to control impairing effects.
