Reaping Slash on Kayn. As the match progresses, it is best to maximise 
Blade's Reach into Reaping Slash and at last 
Shadow Step. Blade's Reach is a very strong ability of Kayn in order to build up a lead and dominate your opponents. The passive is called 
The Darkin Scythe and there is no need to set it manually on a Kayn Build.
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 to champions.
Shadow Assassin: For the first few seconds in combat with enemy champions, deal bonus damage.

- Short Story: The Blade of Millennia by Michael McCarthy
Kayn stood confidently in the shadow of the noxtoraa, surrounded by dead soldiers, and smiled at the irony. These triumphal arches of dark stone were raised to honor the strength of Noxus—to instill fear and to demand fealty from all who passed beneath them. Now this one was a tombstone, a monument to false strength and arrogance, and a symbol of the fallen warriors’ own fear turned against them. - Short Story: The Lure by Dan Abnett
