Nightstalker is a powerful ganker early on with high durability and powerful nuking ability and physical strength. When night falls, no one can escape from his grasp not even able to try to fight back. His natural durability and high night speed allows him to get through towers and creeps to chase heroes fearlessly.
Nightstalker lacks the ability to handle a group of enemy at once, but quite good at disabling enemies both physical and magical and initiate with his ultimate to reduce the vision range.
