The capability of opponents being knocked off the map is a subtle reference to an inside joke where Jesse Perring, a Riot Games Inc. employee who is stated to have taught Lee Sin his Dragon's Rage move, is capable of kicking players off the map.
Active - God Fist: Punches his target, dealing 250 / 450 / 1000 (× SP) magic damage, knocking them back to the edge of the battlefield, and stunning them for 3 / 4 / 10 seconds. Any enemies the target collides with during the knockback are also dealt half the damage and stunned for 1.5 / 1.5 / 10 seconds. If the target cannot be pushed any further, they are knocked out of the battlefield instead, removing them from combat. If the target is still alive, he will dash to them.
