How To Play Kayn Wild Rift ? 

Skill:   

The Darkin Scythe (Passive)

After Kayn has not been in champion combat for a few seconds, his attacks and abilities deal additional damage to enemy champions for a few seconds. This is great for an assassin champion; when you are roaming around the map, keep track of his passive, so when you go in for a fight, you can use all your abilities and auto attacks to deal more damage to the enemies.

Reaping Slash (1)

Kayn dashes and deals physical damage, then spins his scythe to deal the same damage. This ability has two instances of damage. When killing jungle camps, you can use this ability up against the wall to reduce the cast time, meaning you can clear the jungle much quicker. This ability also deals additional damage to minions and monsters.

Blade's Reach (2)

Kayn swipes the scythe upward, dealing physical damage and slowing enemies hit decaying over a second. When playing Shadow Assassin, Kayn can move and use other abilities whilst using Blade's Reach, increasing the ability's range.

You can use Blade's Reach to your advantage at the start of a fight. There will be no channel timing when using this ability, so with the combo above, you can do it quickly and deal a lot of burst damage.

Shadow Step (3)

Kayn gains movement speed (increased in Shadow Assassin form), becomes immune to slows and can move through terrain for a few seconds. Kayn restores health upon entering terrain, so when you are low on health, try to enter any terrain to get a little bit of health back.

The cooldown is also reduced when in Shadow Assassin form. This makes it so you can move around the map much quicker and try to get onto the back line carries to deal a lot of damage.

Umbral Trespass (Ultimate)

Kayn infests an enemy champion for a few seconds, becoming untargetable whilst inside an enemy champion. When the infestation ends, the target is dealt Physical damage. You can recast this ability early to end the infestation early, deal damage quickly, and jump straight back out.

With Shadow Assassin, the ability's range is increased, the distance Kayn can exit is also increased, and it refreshes Darkin Scythe's cooldown. So make sure before you use Umbral Trespass that you use Darkin Scythe so you can quickly refresh the abilities cooldown to deal more damage.
