just stack tal rasha, then meteor them to death while you are channeling for easy high damage. Aquila Cuirass and Karini will keep you very much alive. Molten Wildebeast's Gizzard and galvanizing ward when used with ashnagarr's blood bracer gives a shield of about 700k so you should be readily able to survive most hits that would one-shot you. You can swap the gizzard out for taeguk for more dps if needed. You can also swap out magic weapon - force weapon for magic weapon - deflection for a little more shield mitigation.
I've been doing easy 95s with this build at 950 paragon so i'm sure someone could push this way higher than myself.
