Playing as Rengar
Tips to maximize your impact
- Fight near brush
Fight near brush: from a brush, Unseen Predator (passive) makes your next auto leap onto the enemy.
- Roar after taking damage
Cast Battle Roar (W) right after taking damage in a trade: it heals you for part of the damage taken in the last few seconds.
- Pick your empowered spell
At max Ferocity, pick your empowered spell: Savagery (Q) for damage, Battle Roar (W) to break free of CC, Bola Strike (E) to root.
- Hunt down an isolated carry
Cast Thrill of the Hunt (R) to find an isolated carry: it reveals the nearest enemy champion, then camouflages you and lets you leap without brush.
Playing against Kayn
How to counter and exploit weaknesses
- Dodge his Blade's Reach
Dodge Blade's Reach (W): Umbral Trespass (R) can only target a champion he just damaged, and this ranged hit is how he marks you from range.
- Save your CC for his E
If you have CC, land it during Shadow Step (E): once immobilized, he loses the spell and can't move through walls anymore.
- Save your spells for his exit
Don't cast your spells during Umbral Trespass (R): hidden inside your ally, he's untargetable. Save them for when he bursts out.
- Ward your jungle too
Ward your jungle too, not just the river: Shadow Step (E) lets him go through walls and show up from unexpected paths.
- Pressure him before he transforms
Pressure him before his transformation: until he picks Rhaast or Shadow Assassin, The Darkin Scythe (passive) gives him no healing or bonus damage.
