Playing against Kayn
How to counter and exploit weaknesses
Ward beyond walls: Kayn passes through walls with his E, classic river wards aren't enough.
Blue form (assassin) is squishy: a CC kills him quickly. Red form (Rhaast) has sustain: Grievous Wounds is mandatory.
His R makes him untouchable — don't waste abilities when he's inside an ally.
Before his transformation, Kayn is relatively weak — invade his jungle early to delay his transformation.
