Kayn

Innate: Kayn has a secondary experience bar that tracks progress toward his Rhaast and Shadow Assassin forms. He gathers orbs from champion takedown and each instance of damage (excluding damage over time) dealt against champions. Once he has earned enough orbs, he unlocks a form based on whether he earned more from melee or ranged champions (for Rhaast and Shadow Assassin, respectively), with the other form unlocked later.

Kayn can move near the summoning platform to transform over 6 seconds, restoring to full health and mana and becoming invulnerable, untargetable, and unable to act for the duration. Kayn cannot choose a form if he is unable to cast abilities. The transformation will grant a passive bonus and permanently empower some of Kayn's abilities based on the form chosen. He gains a one-time Homeguard once the transformation is complete.

If this effect is ready, it will not be lost by taking damage.

Both instances of Reaping Slash deal 40 bonus physical damage against minion and monster.

20px|border|link= Darkin Bonus: Reaping Slash's damage is modified to deal 65% AD (+ 6% (+ 3.5% per 100 bonus AD) of the target's maximum health) physical damage with each hit, for a total of 65*2% AD (+ 6*2% (+ 3.5*2% per 100 bonus AD) of the target's maximum health). This damage has a cap against monsters that does not include the bonus damage.

20px|border|link= Shadow Assassin Bonus: Blade's Reach's radius is extended by 200 units. Kayn conjures an untargetable shadow at the casting position to perform Blade's Reach's sweep over 0.55 seconds in his stead, removing the ability's cast time.

Active: Kayn gains 40% bonus total movement speed, ghosting and the ability to ignore terrain collision for a duration. If he has been in combat with enemy champions within the last 3 seconds, Shadow Step will instead last 1.5 seconds.

Kayn heals himself upon entering terrain for the first time from casting Shadow Step and he gains unobstructed vision while inside.

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 immobilize, excluding from sleep, or polymorph.

Passive: Kayn marks enemy champions he damaged in the last 3.15 seconds.

Active: Kayn vanish and dash to a marked enemy champion. Upon arrival, he channel for up to 2.5 seconds, attach to the target and true sight them. Umbral Trespass can be recast after 0.75 seconds during the channel, and does so automatically after the duration or if it is interrupt.

Recast: After a 0.75-second delay, Kayn deals physical damage to the target and dash out from their body in the target direction, detaching himself from them and becoming targetable again at the end of the dash.
