The Shadow Reaper Kyan is one of the best choices for playing in the jungle now. His abilities can not only farm jungle fast but also will help you escape from danger or vice verse engage the fight. Kayn’s passive The Darkin Scythe Kayn wields an ancient weapon and fights Rhaast, the darkin within it, for control. Either the Darkin will triumph, or Kayn will master Rhaast and become the Shadow Assassin. Darkin: Heal for a percentage of spell damage dealt with champions. Shadow Assassin: For the first few seconds in combat with enemy champions, deal bonus damage. Thanks to it you can choose between different playstyles depending on the circumstances in your game. Shadow Assassin is a great choice with a significant amount of burst damage. And Darkin will give up some of your mobility in exchange for mild crowd control, %max HP damage, insane healing, and utility. 

Kayn Rune Set

Our Kayn Rune Set is a bit different from the classical one. You will usually see Conqueror rune first, but it won’t be available in the next season. So you should change it for Press the Attack.
