Beam and don't die (I hope so).
Searing Charge could be in the place of Shadow Walk, and Umbral Edge could be in the place of Arrow Storm if you don't find these with ease.
Essence of Metal or Efficiency could be in the place of Essence of Charcoal (Frostbite)
I level up my Double Tap (passive) to achieve 100% crit chance, then Incendiary Round if I don't have the Essence of Momentum yet. Otherwise, Arrow Storm and Shadow Walk if I don't have the Essence of Virtue yet.
When I can choose between Life, Attack, Attack Speed and Haste: Haste > Attack Speed.
