Roshan, sometimes also referred to as Roshan the Immortal, is the most powerful neutral creep in Dota 2. It is the first unit which spawns, right as the match is loaded. During the early to mid game, he easily outmatches almost every hero in one-on-one combat. Very few heroes can take him on alone during the mid-game. Even in the late game, lots of heroes struggle fighting him one on one, since Roshan grows stronger as time passes.
