Dota 2/Banehallow the Lycan

Lycanthrope, commonly shortened to just Lycan, is a melee strength hero that can play the role of a jungler, a carry or a pusher. He can Summon Wolves to fight with him, overwhelming his enemies. He can let out a loud Howl that boosts his and his allies' damage. His Feral Impulse makes him a faster and deadlier attacker, which will influence his summons. Of course, Lycanthrope isn't just a fancy title. He can willingly Shapeshift into a deadly wolf, greatly enhancing his caombat capabilities.

Summon Wolves
Summon Wolves summons 2 wolves to fight for you. These wolves are very helpful when you're jungling, as they increase your damage output without needing you to get close. The wolves are also much faster than you normally, so they can chase down enemies you can't catch up to. Once they get to level 4, the wolves can also be used to scout, and if you decide to go for a kill, an enemy will easily be caught by surprise if you initiate it with your invisible wolves. These wolves will also benefit from you other abilities, so make note of that.
