Kayn is a slippery, insatiable nightmare who uses his victims' bodies as a recreational vehicle. The Shadow Reaper's ult is horrifying enough, but even scarier is his tendency to emerge, suddenly, from any wall in the Rift.
I hope you enjoy my guide to the Shadow reaper

Hello my name is LordZeta1313 and i am a silver V top main. i have been playing for a little over a year now. i am a YouTuber-in-progress as DarkinBladeGaming. among my champion pool are Aatrox, yorick, gangplank, cho'gath, malzahar, nocturne, swain, darius, sion, and more

I hope you enjoy this guide, which is an updated version of an oudated guide that i made a few months ago (the celerity and DH changes made it obsolete)

Passive: The Darkin Scythe

Kayn wields an ancient, sentient weapon, that battles with him for control. Each instance of damage (excluding damage over time) and takedowns Kayn deals against champions causes them to drop orbs, red by melee champions and blue by Ranged champions, that are automatically collected upon leaving combat, filling their respective bars by 2.5 − 7 (based on minutes) points per orb.
If Kayn is damaged by an enemy champion, he will instantly collect all dropped orbs opposite to the attacker's range type and fill the corresponding bar of his attacker's range type.

If out of combat, and once one of the bars is full, which scales down with game time, Kayn will either be overwhelmed by Rhaast or expel him to become the Shadow Assassin, based if the filled bar is red or blue, respectively. Once primed, the other option becomes available after 4 minutes.

The transformation can only be performed by interacting with their portrait while on the summoning platform, permanently changing their abilities and granting them Homeguard.

SHADOW ASSASSIN: Kayn deals 12% − 44% (based on level) of post-mitigation damage dealt against enemy champions as bonus magic damage, lasting for 3 seconds upon entering in combat with an enemy champion, refreshing after 8 seconds out of combat with them or by using Umbral Trespass.

RHAAST: Rhaast heals for 34.5% − 43% (based on level) of the post-mitigation Attack damage physical damage that he deals with spells against enemy champions

Q: Reaping Slash

Kayn dashes forward, dealing physical damage to all enemies he passes through before flourishing his scythe, dealing the same damage again to surrounding enemies.

The dash's speed scales with Kayn's total movement speed.

RHAAST: Both instances of damage are modified to 50% AD (+ 5% (+ 4% per 100 bonus AD) of target's maximum health) physical damage, capped against monsters.

Both instances of Reaping Slash deal 55 bonus damage against monsters.

PHYSICAL DAMAGE:
60 / 80 / 100 / 120 / 140 (+ 65% bonus AD)

200 / 250 / 300 / 350 / 400

TARGET RANGE: 350

COST: 50 MANA

COOLDOWN: 7 / 6.5 / 6 / 5.5 / 5


W: Blade's Reach
After a short delay in which he can't perform any other actions, Kayn performs an upwards sweep with his scythe, dealing physical damage to all enemies in a line and slowing them by 60% decaying over 1.5 seconds.

SHADOW ASSASSIN: range is increased by 200. Additionally, Kayn conjures a at the casting position to perform in his stead, allowing Kayn to perform other actions.

E: Shadow Step
Kayn gains 40% bonus movement speed, is ghosted and can ignore terrain collision for 1.5 seconds. Immobilizing effects will interrupt shadow step.

Kayn heals himself upon moving through terrain for the first time and, if he's not in combat with enemy champions, duration is increased. While inside terrain, Kayn's vision pierces all obstructions although he cannot see into brush.

Entering combat with a champion after the effect is enhanced reduces the remaining duration to 1.5 seconds. The effect also cannot remain active out of terrain for longer than 1.5 seconds.

SHADOW ASSASSIN: Casting removes Slow icon slows and makes Kayn immune to them for the duration. Additionally, entering terrain will increase the bonus movement speed to 80% for
the remaining duration.

EMPOWERED DURATION:
7 / 7.5 / 8 / 8.5 / 9

PASSIVE: Whenever Kayn damages an enemy champion, he applies for 3.5 seconds.

ACTIVE: Kayn infests a marked enemy champion for up to 2.5 seconds, revealing them and becoming untargetable for the duration. Reactivating ends it earlier.

Upon reactivation or at the end of the duration, Kayn wrenches himself free from their body in the cursor's direction, dealing physical damage to the target.

SHADOW ASSASSIN: gains 200 bonus range and emerging from the target resets The Darkin Scythe's cooldown.

RHAAST: Umbral trespass is modified to deal 10% (+ 13% per 100 bonus AD) of target's maximum health physical damage, and heals him for 7% (+ 9.1% per 100 bonus AD) of target's maximum health.

TARGET RANGE: 550

COST: 100 MANA

COOLDOWN: 120 / 100 / 80

Passive:
This is your biggest strength and biggest weakness. In the early game you essentially have no passive, but in the mid game you get to chose between two different playstyles. Note that Rhaast is more efficient if you are behind, but the Shadow assassin in a nightmare when ahead. Choose wisely.

Q:
This is your bread and butter. Use it as your main damage source that you can land reliably. The dash allows you to keep up with fleeing enemies, shredding their healthbars for making the choice of retreat. RHaast can use this to output percent max health damage reliably.

W:
This is your most damaging ability in the early game, and becomes a massive part of your kit in the late game. Try using it from brush to ensure that you land the high damage. With Rhaast it provides A knockup instead of a slow, and with SA it no longer roots you while you channel it.

E:
This is what makes Kayn a pain to fight. Unlike most top laners, you can roam pretty easily, and pick up a few kills in Mid-lane if you are lucky. I recommend only doing this if the enemy top laner is missing or dead. It is also an option if your turret is destroyed early on. The heal makes for a great escape tool if you need to leave a lost fight. As SA the slow immunity and massive speed boost allows you to make even more escapes. Another trick is to use this to ambush your opponent by moving through the northern wall.

Ultimate:
This is a deadly tool in the right hands. It makes turret diving very easy, and although the damage is not massive, the utility it provides is invaluable. The heal on Rhaast is massive and the Passive reset is lifesaving for SA.

Manamune is mostly for the stay-in-lane-forever type of people. This item fixes Kayn's mana problems. These don't usually don't show up in the jungle due to the presence of blue buff. You E eats up you mana quickly, but with this you should be able use it more often. The extra AD from all that mana is also good

Dead Man's Plate is mostly for Rhaast, as the stats it gives don't benefit SA much. If you want to be a bit risky you can buy this item solely for the passive, as the MS and slowing AA work well with SA's assasinations.


Stormrazor is mostly actually a decent item on Kayn. The stats are okay, but the passive boosts SA's assasinations while the damage is welcome in the teamfights the Rhaast lives for. Note that you will always have Storms edge if you exit you ultimate after the full duration. This item falls off late game as Rhaast simply cannot spend a moment of his Time AAing and SA will often kill his targets without triggering storms edge.

Frozen Heart is an item that should only be used on Rhaast, as the stats are horrible on SA. The attack speed slow is best for the teamfights that Rhaast partakes in often.

Pyke is one of the trickiest lanes to play against, but not because Kayn loses the matchup. If you play it right you will absolutely stomp him. There are two strategies. One is to constantly fight Pyke, getting as man orbs as possible, then you have to wait, because Rhaast is very ineffective against Pyke. SA stomps Pyke, but Pyke is melee, which means attacking him empowers Rhaast. The recommended strategy is to not fight Pyke, at all, seriously, Don't poke, don't harass, just CS and only go in if he makes a major mistake that you can get a kill off of. The reason I recommend this is because You will get Rhaast first. When the game reaches 15 minutes or if you have an almost full bar of red orbs (you shouldn't have any blue orbs at this point unless you get ganked by a ranged jungler) head down mid and try to get a kill. Once you turn into SA proceed to annihilate pyke.

I hope you enjoyed my guide, as i spent a lot of time on it. THis guide is an updated version of A guide i made a while ago. The Runes from that guide are still in this one, though you may have to look a little to find them.

Happy shower(er...soul, yeah soul)hunting!
