Abilities

Edit

The Darkin Scythe

	Innate: Kayn wields an ancient, sentient weapon, that battles with him for control. Enemy champions drop orbs for each instance of damage (excluding damage over time) they receive from Kayn and everytime he scores a takedown against them, red orbs by melee champions and blue orbs by ranged champions. Orbs will remain on the ground until automatically collected by Kayn regardless of range once he leaves combat, filling a bar above his portrait.
	Once the bar is filled, Kayn can return to the summoning platform to interact with his portrait to either be overwhelmed by Rhaast or expel him to become the Shadow Assassin, or wait 4 minutes until the other form becomes available, reduced by 5 seconds for each collected orb of their type after that. After choosing a form, Kayn transforms into Rhaast or the Shadow Assassin over 6 seconds, during which he is invulnerable, untargetable, and unable to act. Kayn cannot select a form if he is unable to cast abilities.
	The transformation type is decided based on the highest amount of damage dealt to the respective range type. If the two forms are within 8% of each other, the last champion range type hit will determine the transformation. If both types are hit at the same time the trasformation will default to Rhaast. The transformation will permanently empower some of Kayn's abilities and grant him Homeguard for the first time.
	Shadow Assassin: If Kayn has been out of combat with enemy champions for over 8 seconds, or he casts Umbral Trespass, he deals 12% − 44% (based on level) of post-mitigation damage dealt against enemy champions as bonus magic damage, lasting for 3 seconds upon entering combat and also applying on the first instance of damage dealt. If this effect is ready, it will not go on cooldown by receiving damage.
	Darkin: Rhaast heals for 30% − 40% (based on level) of the post-mitigation physical damage that he deals to enemy champions with his abilities.
"I am the shadow of death."      "Oh, the wrath I will unleash!"

Targeting input	Passive

Notes

• The bar gets filled up completely at 500 points.
  • Melee orbs grant 2 points per hit and 6 points per takedown.
  • Ranged orbs grant 3 points per hit and 7 points per takedown.
  • Each bar has a bucket system.
    • The bucket starts at 60 points.
    • Each time an orb is taken the system checks if there's an amount of points in the bucket equal to or higher than the amount received from the orb.
      If there is, Kayn is given an additional orb of the same type he received, while also subtracting that amount of points from the bucket.
    • The bucket fills by 0.8 points per second if out of champion combat for 70 seconds.
  • The amount of points received per orb is then multiplied by 3 − 10.39 (based on minutes).
• The orbs will be collected even if Kayn dies.
• Entering transformation will not destroy in-flight projectiles.

Reaping Slash

TARGET RANGE: 350 EFFECT RADIUS: X SPEED: X + X% Movement speed CAST TIME: none COST: 50 Mana COOLDOWN: 7 / 6.5 / 6 / 5.5 / 5

	Active: Kayn dashes in the target direction, dealing physical damage to enemies he passes through, before swinging his scythe, dealing the same damage to surrounding enemies.	Physical Damage: 75 / 95 / 115 / 135 / 155 (+ 65% bonus AD) Total Champion Damage: 150 / 190 / 230 / 270 / 310 (+ 130% bonus AD)
	Both instances of Reaping Slash deal 40 bonus damage against minions and monsters.	Non-Champion Damage: 115 / 135 / 155 / 175 / 195 (+ 65% bonus AD) Total Non-Champion Damage: 230 / 270 / 310 / 350 / 390 (+ 130% bonus AD)
	Darkin: Reaping Slash's damage is modified to deal 55% AD (+ 5% (+ 4% per 100 bonus AD) of the target's maximum health) physical damage for both instances. This damage is capped against monsters but does not include the bonus damage.	Capped Monster Damage per Hit: 200 / 250 / 300 / 350 / 400 Total Capped Monster Damage: 400 / 500 / 600 / 700 / 800
	The dash's speed scales with Kayn's  total movement speed.

Notes

• Spell shields will block only a single instance of damage - either the dash or the slash.
• If the dash is interrupted, Kayn will not swing his scythe.
• Reaping Slash's swing can be performed quicker if the dash stops prematurely upon colliding with terrain.
• As the Shadow Assassin, an alternate icon for Reaping Slash is used but has no modified effect.
• Other abilities can be queued while casting Reaping Slash.
• All item actives can be used during Reaping Slash.
  • Stopwatch and Zhonya's Hourglass will not stop the dash or the damage from occurring.
  • Using an item active that has a dash (e.g. Hextech Rocketbelt, Galeforce) will override Reaping Slash's dash if used before it ends, preventing the slash from happening. If used after Reaping Slash's dash ends, Kayn can reposition where the slash happens.

Blade's Reach

TARGET RANGE: 700 / 900 WIDTH: X CAST TIME: 0.55 / None COST: 60 / 65 / 70 / 75 / 80 Mana COOLDOWN: 13 / 12 / 11 / 10 / 9

	Active: Kayn performs an upwards sweep with his scythe in the target direction, dealing physical damage to all enemies within a line and slowing them by 90% decaying over 1.5 seconds.	Physical Damage: 90 / 135 / 180 / 225 / 270 (+ 130% bonus AD)
	Shadow Assassin: Blade's Reach's range is increased by 200. Additionally, Kayn conjures an untargetable living shadow at the casting position to perform Blade's Reach's sweep over 0.55 seconds in his stead, reducing the ability's cast time to 0.
	Darkin: Blade's Reach also knocks up enemies hit for 1 second.

Edit

Shadow Step

CAST TIME: none COST: 90 Mana COOLDOWN: 21 / 19 / 17 / 15 / 13

	Active: Kayn gains  40% bonus movement speed, ghosting and the ability to ignore terrain collision for a duration. If Kayn has been in combat with enemy champions within the last 3 seconds, Shadow Step will instead last 1.5 seconds.	Duration: 7 / 7.5 / 8 / 8.5 / 9
	Kayn heals himself upon moving through terrain for the first time from casting Shadow Step and he gains unobstructed vision while inside.	Heal: 100 / 115 / 130 / 145 / 160 (+ 40% bonus AD)
	Receiving damage from or dealing damage to an enemy champion while Shadow Step is active reduces its remaining duration to 1.5 seconds. This effect also cannot remain active out of terrain for longer than 1.5 seconds and will cancel immediately if Kayn performs a basic attack or becomes immobilized or polymorphed.
	Shadow Assassin: Shadow Step's  cooldown is reduced to 8 seconds at all ranks. Additionally, Kayn gains 100% slow resist and, upon entering terrain, the bonus movement speed is increased to 80% for the remaining duration.

Notes

• As Rhaast, an alternate icon for Shadow Step is used but has no modified effect.
• The bonus movement speed stacks multiplicatively with other sources of movement speed boosts.
• Self immobilizations such as Stopwatch / Zhonya's Hourglass also count for interrupting Shadow Step.
• Recall is disabled while Kayn is inside terrain.
• Enemies cannot see Kayn while he is inside of terrain unless they have terrain-piercing vision, such as Heightened Senses, Hawkshot or unobstructed vision.
  • However, enemies and allies (including Kayn) will be notified if nearby terrain is infested if Kayn is within 1000 units - with an indicator being placed on the terrain with a direct line between Kayn and the enemy champion. Slightly less than standard sight radius, but more than the camouflage detection radius.
• Kayn can move up to 550 units beyond the outer-edge of the battlefield.
• Shadow Step can interact with player-generated terrain.
• If Kayn is inside terrain when the effect ends, he will be placed correspondingly to the nearest valid space.
• Sleep will not interrupt Shadow Step.*

Edit

Umbral Trespass

TARGET RANGE: 550 / 750 EFFECT RADIUS: 300 / 500 CAST TIME: none COST: 100 Mana COOLDOWN: 120 / 100 / 80

	Passive: Kayn marks enemy champions he damaged in the last 3.15 seconds.
	Active: Kayn vanishes and dashes to a marked enemy champion. Upon arrival, he channels for up to 2.5 seconds, attaching to the target and revealing them. Umbral Trespass can be recast after 0.75 seconds during the channel, and does so automatically if the channel ends without reactivation or is interrupted.
	Recast: After a 0.75-second delay, Kayn deals physical damage to the target and dashes out from their body in the target direction while still being untargetable.	Physical Damage: 150 / 250 / 350 (+ 175% bonus AD)
	Shadow Assassin: Umbral Trespass gains up to 200 bonus cast range and emerge range. Additionally, emerging will reset The Darkin Scythe's  cooldown.
	Darkin: Umbral Trespass is modified to deal 10% (+ 13% per 100 bonus AD) of the target's  maximum health physical damage, and heals him for 7% (+ 9.1% per 100 bonus AD) of target's maximum health.

Notes

• The initial cast counts as an ability activation for the purposes of on-cast effects such as Spellblade.
  • Detonating the ability manually does not.
  • The ability activation happens when Kayn is attached to his target and the channel starts.
    • Kassadin cannot gain a stack for Force Pulse because Kayn is untargetable during the activation.
• The ability will recast if Kayn is ordered a movement command.
• The amount of time it takes for Kayn to attach to his target is between 0.5 seconds (cast from max range, not as Shadow Assassin) and 0.25 seconds (cast from point blank range).
  • This duration is fixed, meaning Kayn will attach regardless of how far away the target gets while he is dashing toward them.
• If the target dies, enters resurrection, or is sent to the Realm of Death while Kayn is attached, he will instantly detach and reappear on top of the target's location. This does not occur if Kayn is in the process of emerging from the target.
  • If those same conditions occur before the attachment, Kayn will reappear at the target's location after completing the dash. There is no compensation if this happens.
  • Kayn will automatically emerge when attached to a clone that expires.
• If Kayn dies while attached and the recast is available, Umbral Trespass' damage is dealt immediately. If the recast is not available, Umbral Trespass' damage is not dealt at all.
  • Entering resurrection while attached does not deal Umbral Trespass' damage regardless of if the recast is available or not. Kayn will still detach in this case.
• During Umbral Trespass, Kayn will not take the self-inflicted damage from Death's Dance's Ignore Pain.
• As Rhaast, Umbral Trespass will not heal if the target dies during the 0.75-second delay before emerging.
• Umbral Trespass' interactions with crowd control:
  • Being stunned or silenced or falling asleep while attached will cause the ability to recast automatically (even during the 0.75-second delay before Kayn is able to recast after attaching).
  • Umbral Trespass cleanses Kayn from drowsiness.
  • Kayn is immune to fear during Umbral Trespass.
  • Roots will not prevent Kayn from initiating the recast.
  • Displacements cannot interrupt the initial dash and neither can they apply while Kayn is attached. If the airborne source applies a debuff, Kayn attaches to his target immediately, ending the dash prematurely in the process. The debuff is also removed instantly.
• Until the recast or after the duration, the ability will have had no effect on the target for the purposes of Electrocute or the 'in-combat' status.
• Spell shields will prevent Kayn from infesting the target, but will do nothing to mitigate the recast when used once he has already infested them.
  • If Kayn targets an enemy that is currently being protected by a spell shield, the ability will simply go on cooldown without making him infest his target.
    • This is also true for Fiora's Riposte.
• Umbral Trespass cannot be cast on targetable zombie states such as Sion during Glory in Death.
• The damage is not blocked if the target becomes untargetable.
• Kayn will copy his target's total size for Umbral Trespass' duration, even if their size is smaller than his.
• The screen will direct to the target's position upon attaching.
• As Rhaast, an alternate icon is used for the initial activation of Umbral Trespass.

V7.14 Added

  • Shadow Assassin: Kayn's basic attacks and abilities deal 12% − 44% (based on level) of post-mitigation damage 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.
