Need help with Purifier


Any suggestions how to improve my Purifier? Since my tanky skills come from life leech I got two huge troubles: healing away huge single dmg and getting stunned.
Because my build is extremely simple and funny to play with, I want mainly improving healthpoints and stun ress.
Obviously I lack the right gear - any suggestions for the right items for this build and farming locations (max Act 5).
