1st advise, get rid of that leoric signet. The amount of xp you will be getting is good enough especially in party's without the ring. A replacement ring to  buff your dps and ehp by a mile hence allowing you to farm xp efficiently. Your ehp is wayyyyy too low and your Vit definitely needs a major buff. I would prefer using a lifesteal skorn so that I can use better passive. Using bloodthirst very rugi one passive slot. Even a 4.+ LS of skorn is good enough together with immortal king's belt but for a skorn user, definitely recommend using WH for the additional AS.
