I played a few games with this build! Its still day one so Im sure everyone will be trying many different builds But I found this to be good to start.

Rotation: Verdant Spheres, Gravity Lapse, Flamestrike, Living Bomb

When you have your ULT, if you can get it off before initiation, use Pyroblast and then the above rotation. If you cant Use Pyroblast first, Stun them and then Ult, Living Bomb, and use your Flamestrike to pick them off as they run away!

This is my first build guide so bare with me as I work through it.
