Blink + Charcoal + Rigidity provides initiation with a barrier from the start. Glacial core will become the engine that continues to power charcoal and Rigidity for damage and barrier.
Umbral Edge powered auto attacks will be the primary source of damage and should generate steady healing, barrier, and attack speed boost. This healing will work to keep us topped off and feed the Glacial Core for more healing and damage.
Frostbite will provide some on demand shield and burst damage with the help of Giant. Focus on stacking Essence of Frost as often as possible.
Arrow Storm and these essences will be the icing on the cake that will multiply everything else going on .
