Don't always select the same Kayne form. Make note of what players are chosen on each time before selecting Kayne's form.
Select Shadow Assassin if your team needs extra damage or if you need to eliminate a hyper carry in team fights.
Darkin Kayne has much more sustain, but can still deal plenty of damage. Choose the Darkin form if you need more sustain in fights.
You build blue essence (shadow) by attacking ranged champions and red essence (darkin) for damaging melee enemies.
LoL Kayn players may find him to be a complex champion to build out properly. You will see that his build varies when he is fighting either generic or homogenous team compositions, indicating you should not select the same Kayn build every single round of League of Legends
The most essential items to include in your champion's build include: Prowler's Claw, Guardian Angel, and Death's Dance. Those who added these items in their builds had a greater winrate than players who utilized other builds for Kayn. Likewise, if you are trying to beat a well-mixed enemy team arrangement, you should really consider grabbing him the Domination, and Inspiration runes. In recent games, he won the largest fraction of his rounds when equipped with these runes.
We set our Kayn build guidance by analyzing 146,307 recently ranked League rounds with him selected. We only advise the highest winrate Kayn builds that were used by ranked players enough times for us to advise them. With so many rounds in our dataset, we are quite confident in our suggested builds.
