Playing against Kayn

How to counter and exploit weaknesses

1

Ward beyond walls: Kayn passes through walls with his E, classic river wards aren't enough.

2

Blue form (assassin) is squishy: a CC kills him quickly. Red form (Rhaast) has sustain: Grievous Wounds is mandatory.

3

His R makes him untouchable — don't waste abilities when he's inside an ally.

4

Before his transformation, Kayn is relatively weak — invade his jungle early to delay his transformation.
