Kayn's Abilities

The Darkin Scythe 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.

Reaping Slash Kayn's Q Ability

Kayn dashes forward, dealing 75 / 95 / 115 / 135 / 155 (+0.65 per bonus attack damage) physical damage to all enemies he passes through before flourishing his scythe, dealing the same damage again to surrounding enemies.

Both instances of Reaping Slash deal 40 bonus damage against minions and monsters.

7 / 6.5 / 6 / 5.5 / 5

Blade's Reach Kayn's W Ability

After a short delay in which he can't perform any other actions, Kayn performs an upwards sweep with his scythe, dealing 90 / 135 / 180 / 225 / 270 (+ 1.3 per bonus attack damage) physical damage to all enemies in a line and slowing them by 90%, decaying over 1.5 seconds.

60 / 65 / 70 / 75 / 80

13 / 12 / 11 / 10 / 9

Shadow Step Kayn's E Ability

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 by 100 / 115 / 130 / 145 / 160 (+ 0.4 per bonus attack damage) upon moving through terrain for the first time and, if he's not in combat with enemy champions, Shadow Step's duration is increased to 7 / 7.5 / 8 / 8.5 / 9 seconds.

Entering combat with a champion after the effect is enhanced reduces the remaining duration to 1.5 seconds.

21 / 19 / 17 / 15 / 13

Umbral Trespass Kayn's Ultimate (R) Ability

550

120 / 100 / 80 / 80 / 80

Kayn's The Darkin Scythe: Shadow Assassin

The Darkin Scythe: Shadow Assassin Kayn's Passive

Kayn's basic attacks and abilities deal 8-30% of post-mitigation damage as bonus magic damage (depending on level), 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.

Reaping Slash: Shadow Assassin Kayn's Q Ability

Blade's Reach: Shadow Assassin Kayn's W Ability

7 / 6.5 / 6 / 5.5 / 5

After a short delay, Kayn conjures a living shadow at his casting position that performs an upwards sweep with its scythe, dealing 90 / 135 / 180 / 225 / 270 (+ 1.3 per bonus attack damage) physical damage to all enemies in a line and slowing them by 60%, decaying over 2 seconds.

Shadow Assassin grants Blade's Reach 200 bonus range.

60 / 65 / 70 / 75 / 80

13 / 12 / 11 / 10 / 9

Shadow Step: Shadow Assassin Kayn's E Ability

Kayn removes slows on himself, 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 by 100 / 115 / 130 / 145 / 160 (+ 0.4 per bonus attack damage) upon moving through terrain for the first time and, if he's not in combat with enemy champions, Shadow Step's duration is increased to 7 / 7.5 / 8 / 8.5 / 9 seconds.

If Kayn enters terrain at least once, Shadow Step will be improved for the remainder of its duration to grant 80% bonus movement speed and make Kayn immune to slows.

Entering combat with a champion after the effect is enhanced reduces the remaining duration to 1.5 seconds.

Umbral Trespass: Shadow Assassin Kayn's Ultimate (R) Ability

750

100

120 / 100 / 80 / 80 / 80

Passive: Kayn's basic attacks and abilities mark enemy champions for a few seconds.

Active: Kayn can activate Umbral Trespass to infest a marked enemy champion for up to 2.5 seconds, revealing them and becoming untargetable for the duration. Reactivating Umbral Trespass ends the effect early.

Upon reactivation or at the end of the duration, Kayn wrenches free from their body in the cursor's direction, dealing 150 / 250 / 350 (+ 1.75 per bonus attack damage) physical damage to the target.

Shadow Assassin form grants Umbral Trespass 200 bonus range and emerging from the target resets The Darkin Scythe's cooldown. Kayn can also exit between 300 and 500 units away from his host based on cursor position.

The Darkin Scythe: Rhaast Kayn's Passive

Rhaast heals for 30-40% of the post-mitigation damage that he deals with spells against enemy champions (depending on level).

Reaping Slash: Rhaast Kayn's Q Ability

Kayn dashes forward, dealing 55% of his total attack damage (+5% (+4% per 100 bonus attack damage) of target's maximum health) physical damage to all enemies he passes through before flourishing his scythe, dealing the same damage again to surrounding enemies. The damage against monsters is capped at 200 / 250 / 300 / 350 / 400.

Both instances of Reaping Slash deal 40 bonus damage against monsters.

7 / 6.5 / 6 / 5.5 / 5

Blade's Reach: Rhaast Kayn's W Ability

After a short delay in which he can't perform any other actions, Kayn performs an upwards sweep with his scythe, dealing 90 / 135 / 180 / 225 / 270 (+ 1.3 per bonus attack damage) physical damage to all enemies in a line, knocking them up for 1 second, then slowing them by 60%, decaying over 1.5 seconds.
