Kayn is currently ranked in Tier B for the Jungle role. This suggests he is a middle-of-the-pack performer compared to other junglers in the current meta. His carry score is a moderate 5.8 out of 10 based on analysis of over 3,000 games.

Kayn Jungle currently holds a win rate of 48.5% in Platinum+ ranked games. While this is slightly below the 50% mark, specific high-performing builds can significantly increase this percentage. His pick rate remains stable at 5.8% with a 3.6% ban rate.

Based on Platinum+ data, Kayn is a Tier B champion with a high difficulty rating of 8 out of 10. While he has carry potential, his current win rate of 48.5% suggests he might be challenging for players who haven't mastered his unique transformation mechanics. Players in lower tiers should practice his pathing extensively due to his complex playstyle.

Kayn is a high-skill champion with a difficulty of 8/10, making him rewarding for dedicated players despite his current Tier B status. His skill max order of Q into W into E has an impressive 67.0% win rate, showing that mastery is highly effective. If you enjoy a flexible Fighter and Assassin playstyle, he is a solid choice.

Kayn's overall win rate is currently 48.5%, which is slightly low for the Jungle role. This is likely due to his high difficulty level and the fact that there were no direct buffs to his kit or items in Patch 16.2.1. However, his core item builds like Eclipse and Black Cleaver still maintain very high individual win rates.

Youmuu's Ghostblade is the best first item, yielding a 54.0% win rate over 152 games. It provides necessary mobility and early damage to help Kayn reach his transformation faster. This item significantly outperforms his general 48.5% win rate when rushed early.

Kayn is a versatile pick who can function as both a Fighter and an Assassin, though he is currently in Tier B. You should pick him when your team needs a flexible jungler who can adapt their build, especially since his Q max builds reach a 67.0% win rate. He is best picked when you are comfortable with his 8/10 difficulty rating.

Kayn's primary power spike occurs when he completes his first item, Youmuu's Ghostblade, which raises his win rate to 54.0%. Another major spike happens as you max your Q and W abilities, which leads to a 67.0% win rate. Play aggressively around these item completions to snowball your lead into the mid-game.

Kayn is strongest in the mid to late game once he has secured his transformation and core items like Eclipse and Black Cleaver. While his base win rate is 48.5%, his core 3-item builds reach win rates between 57.0% and 59.0%. His early game is mainly focused on farming and gathering orbs to reach these powerful item milestones.

Kayn received no direct changes in Patch 16.2.1. Additionally, there were no changes to his core items or runes in this specific update. His performance remains consistent with his Tier B ranking from previous data.

The data suggests that the Conqueror setup is the most reliable choice, maintaining a 49.0% win rate. While you should always consider enemy compositions, the primary path of Precision with Triumph, Legend: Haste, and Last Stand is the standard for his Fighter playstyle. Secondary runes like Axiom Arcanist are also highly effective for ultimate uptime.
