Issues with my shadow trickster build

I have been playing with a friend (first proper playthrough). I noticed i started dying a lot quicker and noticed my energy shield wont go above 25/800. Is there an item that causes this? i cant see it anywhere.
Thanks in advance

Your character isn't public so i can't be sure, but that sounds like you have the Ghost Reaver keystone allocated on your tree and very little evasion (25) it should fix by getting more Evasion/ES armor or refunding Ghost Reaver.
