Kayn Counters

Learn 's counters and discover matchups where they have an advantage! When you're starting a game of League of Legends you should always keep in mind if you'll be at an advantage or disadvantage against your opponent, so you can know whether to bully them or play safe. You can find detailed breakdowns of each matchup on CounterStats, and you can also check out some Kayn guides to see how to build and play against other champions you may find yourself up against!


This counter data is for Kayn Jungle in Plat+ games. The percent shown is the enemy champion's counter rating against Kayn. Counter rating is our own statistic that factors in counter kills, overall kills, early lead ratio, comeback ratio, and win percent to give the whole picture of that champion's effectiveness as a counter pick.

Kayn Skins

Kayn's Abilities

Self
Kayn's Passive
Kayn's Passive
Kayn wields an ancient, sentient weapon that battles with him for control. Dealing damage against champions causes them to drops orbs that are automatically collected upon leaving combat, filling a bar above Kayn's portrait.

Once the bar is full, he can choose to either be overwhelmed by Rhaast or expel him to become the Shadow Assassin, based on whether he has damaged more melee or ranged champions, respectively. Once primed, the other option becomes available after 4 minutes. Kayn can continue collecting orbs for his other form to reduce the wait time.

The transformation can only be performed by interacting with Kayn's portrait while on the summoning platform, permanently changing his abilities.
