I am stuck with my first character on Legendary Act 3. I am playing on smartphone. I die way too fast to the Dragon enemies to continue. I am not sure what the problem is or what to do about it. I tried farming the Hydra in Act 1, but its drops don't seem better than what I have. Would someone please give me advice on how to continue? I would hate for the ride to end here. Thank you in advance!

I am trying to post pics of my build, hopefully I do it right .
