1) Separate mages from Tal Rasha, so you can keep your amazon form. With Wild and Free walk speed you will avoid their missiles very easily, using hit-and-run strategy. Clean the most part of Lost City for that reason;
2) Obviously, bring more resists to your char. Use perfect gems in most of your gear. Drink potions if you see your hp falling down below 50%. Then, use fire elementals to tank mages while you perform an attack.
Good luck!
