Stuns, slows and knock-ups lose fights. Our data documents only a few answers, so this guide is short on purpose.
A hero who is locked down cannot dodge or cast. The game offers few clean answers to crowd control, and these are the ones our data describes.
Numbers and effects below are the in-game text from our database, not typed in by hand.
