Riot has revealed the latest champion, Kayn, The Shadow Reaper. Kayn has two forms, Shadow Assassin, a normal-good-boy form, and Darkin, an evil-demon-form. Darkin should be familiar to anyone in the know with Aatrox’s lore, as they are a race of malevolent demon-people. Kayn’s scythe, Rhaast, is one of those demon-people.

Here is his super weird kit:

Passive: The Darkin Scythe

Kayn wields an ancient weapon and fights the darkin within it, Rhaast, for control. During each game, one will consume the other. Kayn hones his shadow skills by hunting ranged opponents, while Rhaast fuels his bloodlust by going toe-to-toe with melee enemies. If Kayn wins the struggle, he ascends to become the shadow assassin. If Rhaast is the victor, the darkin consumes his host and takes center stage.

Shadow Assassin: Deal bonus magic damage during the first few seconds of combat with champions.

Darkin: Heal for a chunk of all spell damage dealt to champions.

Q: Reaping Slash

Kayn dashes forward, striking nearby enemies at the end of the dash. Both the dash and the strike itself deal physical damage. Reaping Slash deals bonus damage to monsters.

Darkin: This ability deals bonus percent-health damage against all enemies except minions.

W: Blade’s Reach

Deal damage in a line that significantly slows all enemies hit.

Shadow Assassin: Leaves behind a living shadow that casts Blade’s Reach in Kayn's stead. The living shadow's Blade has increased range.

Darkin: Blade’s Reach briefly knocks up struck enemies.

E: Shadow Step

Kayn gains a burst of movement speed and the ability to walk through walls for a few moments. When he first enters a wall, he'll heal for a small amount and the duration of Shadow Step will be greatly extended. Kayn won't get the duration extension if he's in combat with enemy champions.

Shadow Assassin: Gain additional movement speed and immunity to slows when activating Shadow Step.

R: Umbral Trespass

Kayn may infest any nearby enemy champion who he has recently damaged. Trespassing into a champion makes Kayn untargetable for a few seconds. Reactivating the ability during this period ends the effect early. Kayn then wrenches himself free from his victim's body, dealing a burst of damage.

Shadow Assassin: Umbral Trespass can be cast from further away and resets the bonus magic damage from The Darkin Scythe after Kayn's exits his victim.

Darkin: Umbral Trespass deals extra damage as a percentage of the victim's maximum health, healing the Darkin in the process.
