the Shadow Reaper
Patch 26.20 · Stats from the 26.18 Master+ sample (1,954 games).
Kayn, the Shadow Reaper, walks through terrain with Shadow Step and hides inside an enemy with Umbral Trespass, while his scythe makes him choose between Rhaast and the Shadow Assassin. Counted Master+ Kayns were junglers who took Dark Harvest more than Conqueror, opening their most common path on Voltaic Cyclosword. He came out ahead of Shyvana and Graves. Against Viego, Wukong and Master Yi he was close to even.

Avoid extended fights — its sustain grows with every trade it survives
Deny the reset — it wants a kill to come back out; a warded exit removes it
Punish the cooldown — Kayn is exposed while its rotation is down
Ward the flank — vision is what turns its best opening into a worse one
Respect the spike — Riot rates the kit 8/10, so a practised player gets more out of it than the average

Riot's notes from patch 25.S1.1 to 26.20 change Kayn in 5 patches. The latest is patch 26.3, published 2026-02-03.
QReaping Slash
Blue Kayn specifically became much weaker in the new season and we'd like to fix that with some direct buffs. There's not much fancy here except that as an assassin, he should be lethal when fighting up close and personal with his targets. As a reminder, Slayer Kayn replaces his Q when transformed.
PThe Darkin Scythe
Shadow Assassin Kayn is a bit too good at taking down his targets at the moment so we're here this patch to give them a fighting chance. We don't want Rhaast to be caught in the crossfire of these nerfs so we're taking aim at some of Blue Kayn's assassin-specific damage that often comes in the form of W poke from the fog of war.
QReaping Slash
WBlade's Reach
There are a decent number of lane Kayn (Layn) players out there and we'd like to give them a fair shot at winning their games. To do that without buffing Jayn (jungle Kayn), we're buffing mana costs to give him better access to wave clear and scrapping with his lane opponent.
Base Stats
Kayn has been an above average champion as of late, and Blue / Red Kayn are actually fairly even in terms of winrate, which is pretty cool! As a result, we're going for a generic nerf to both Kayns that won't hurt his already weak early game, and won't change the actual feel of the champion.
PThe Darkin Scythe
Base Kayn and Red Kayn are about where we want them power-wise, but Blue Kayn isn't performing quite well enough. He doesn't need more late game burst, so we're raising up the floor of his passive a bit to give him a more powerful spike upon transforming that he can use to try to snowball the game.
Riot's data lists 9 looks for Kayn with their own art, the base skin included and 27 chroma variants.

Riot Data Dragon 16.20.1. Growth curve: League of Legends Wiki — Champion statistic.
Kayn, the Shadow Reaper, is a Fighter and Assassin champion in League of Legends. Riot rates the kit 8/10 for difficulty, 10/10 for attack, 6/10 for defense and 1/10 for magic. Kayn spends Mana and has 9 skins with their own art. Kayn's base armor of 38 is the 9th-highest of 173 champions on patch 26.20 (shared with 4 others).
A peerless practitioner of lethal shadow magic, Shieda Kayn battles to achieve his true destiny—to one day lead the Order of Shadow into a new era of Ionian supremacy. He wields the sentient darkin weapon Rhaast, undeterred by its creeping corruption of his body and mind. There are only two possible outcomes: either Kayn bends the weapon to his will... or the malevolent blade consumes him completely, paving the way for the destruction of all Runeterra.
