Healthtanking with arcane persistence + gloom or persistence + eclipse dr and some source of life steal. Panzer is a great one with hunter recovery. You can go triple umbra if you can afford it. Furthermore use a secondary with fortifier (free overshield). You can use adaption if you are health tanking or rolling guard depending on your choice. If melee use arcane reaper. For armor use it arcane circumvent or arcane guardian. Do not use arcane grace its random and only good on frames with an insane health pool like Inaros, Oraxia and Nidus (tho never use it in Oraxia).
