Yeah, it’s a spell from Heroes of the Storm. Demon Hunters are based on Illidan in HoTS. The Hunt is the funnest ability in that game. I might actually pick up my DH if this is the case.
It can easily be OP, though. They have nerfed The Hunt down to just being a distance closer and 1-second stun in Heroes.
It also has a 90-second CD last I played.
