Every Item in this build has a good Build path except Rylias Crystal Scepter. Because of this, the build should keep you in line with your enemy and gives you plenty of power spikes in defense.

Number 1 thing to remember you will be healing a ton, so you are weak to burst. If there are 3 or more enemies don't initiate. Wait for someone else to or just keep poking them and running away. You will heal significantly faster. When you slow the game down and stall out fights you should win.
