How to play and combo preview

Kayn is a jungler fighting Rhaast, the Darkin of his weapon: either Rhaast triumphs (healing based on the ability damage dealt to champions), or Kayn masters him and becomes the Shadow Assassin (bonus damage in the first seconds of a fight). Shadow Step lets him pass through terrain and his ultimate hides him inside an enemy to deal huge damage.

How to play against Kayn

• Umbral Trespass requires Kayn to damage a target first. Try to dodge Blade's Reach to deny him a long range cast of Umbral Trespass.
• When Kayn is in terrain near you, you will get a visual warning on the edge of the terrain he's in.
• Damage Kayn while he's in Shadow Step to shorten its duration, or apply hard crowd control (stun, charm, knockup, etc) to end Shadow Step immediately.
