What is Fear?

Fear is a status effect in Dota 2 that forces a hero to run away from the enemy for the duration of the effect. During this time, the player completely loses control over their hero — they cannot attack, use abilities, or activate items, making them vulnerable to attacks and other forms of control.
Fear is especially useful for scattering enemies and creating chaos during fights, as affected heroes are unable to coordinate with their team or follow planned strategies. This effect can effectively disrupt engagements by forcing opponents to flee without resistance.
