Shaco's basic attack critically strikes for extra damage when striking a unit from behind. Units can't be Backstabbed more than once every few seconds, modified by Shaco's cooldown reduction.
Shaco becomes invisible and teleports to target location. His next attack is guaranteed to critically strike.
Shaco creates an invisible, animated Jack-in-the-Box, which will fear, and then attack, nearby enemies.
Shaco's Shivs passively poison targets on hit, slowing their movement speed. Against minions and monsters the poison also slows attack speed. He can throw his Shivs to deal damage and poison the target.
Shaco creates an illusion of himself near him, which can attack nearby enemies. (Deals half damage to turrets.) Upon death, it explodes, dealing damage to nearby enemies.
Crafted long ago as a plaything for a lonely prince, the enchanted marionette Shaco now delights in murder and mayhem. Corrupted by dark magic and the loss of his beloved charge, the once-kind puppet finds pleasure only in the misery of the poor souls he torments. He uses toys and simple tricks to deadly effect, finding the results of his bloody “games” hilarious—and for those who hear a dark chuckle in the dead of night, the Demon Jester may have marked them as his next plaything.
