I am trying to follow a wave of light build, but every time i cast it, it activates on my hero as an AOE around myself.
I thought it was a ranged attack? I see tons of youtube videos where guys are casting it from a screen length away.
Do i need a specific item? I'm missing something here...
Try using it with epiphany
You need Tzo Krin's Gaze.
