What is Stun?

Stun is a status effect in Dota 2 that completely disables a hero's ability to move, cast spells, use items, or attack for a certain duration. An enemy affected by a stun becomes vulnerable and cannot respond to anything happening around them while the effect lasts. Stuns are one of the strongest forms of crowd control in the game and are often used to initiate fights or prevent enemy heroes from escaping.
