Rengar

Rengar is built around ambushing from the tall grass. Through his passive, Unseen Predator, his basic attack can launch him at a target whenever he stands in brush, so every grassy patch on the map becomes a possible strike zone. Each ability cast builds Ferocity, and at maximum Ferocity his next ability comes out empowered. Playing him well means managing that rhythm: stack Ferocity fast, then pick the empowered effect that fits the fight.

Every basic ability pays off when Ferocity is spent. Savagery deals bonus damage on a stab, and when empowered it hits harder and grants attack speed, which suits dueling or chewing through objectives. Battle Roar hurts nearby enemies and heals him for recently taken damage; empowered, it breaks crowd control. Bola Strike slows from range and, when empowered, roots, giving him the lockdown assassins depend on. The real skill is saving Ferocity for the right empowered cast instead of firing it off the moment it is available.

Thrill of the Hunt is his signature ultimate. Rengar turns invisible, gains movement speed, and marks the closest enemy champion within a wide radius, then leaps at that marked target. The result is a unique kind of pressure: the enemy carry knows a hunter is near, cannot see him, and must respect a leap that is hard to predict.

Rengar is listed for mid and top lane as a snowballing Assassin/Fighter. He suits aggressive players who like ambushes, one-shot combos, and showing up exactly where the opponent least expects. The cost is commitment: he goes all in on a dive, and if the burst does not finish the job, he has few ways to escape.
