Rengar

Innate: Upon casting a Champion ability or using Savagery first attack, Rengar generates a stack of Ferocity for 1.5 seconds, refreshing on subsequent triggers and stacking up 4 times. At maximum stacks, his next basic ability consumes them all to become empowered with an additional effect and grant him an additional cast along with 30% / 40% / 50% bonus movement speed for 1.5 seconds. Generated Ferocity is prevented from expiring for 10 seconds after entering champion combat. Reaching 4 Ferocity with Savagery or Bola Strike locks the empowered version of the ability from being cast for 0.1 seconds. Similarly, consuming all Ferocity with an empowered ability locks the unempowered version of the ability from being cast for 0.1 seconds if it is not already on cooldown, increased to 0.25 seconds for Battle Roar.

Innate: While in brush, Rengar gains Unseen Predator, which lingers for 0.35 seconds upon exiting brush. Unseen Predator is lost immediately if Rengar exits the brush using Flash or Hexflash.

Unseen Predator: Rengar's basic attacks have massively increased range and cause him to dash to the target's location if they are beyond his normal basic attack range, triggering on-attack effects, and attacking the target upon arrival and landing closer than his normal melee range. Unseen Predator will generate 1 Ferocity if none of his current Ferocity was generated this way. Rengar can cast any of his abilities during the dash.

Bonetooth Necklace Innate - Bonetooth Necklace: Scoring a takedown against an enemy champion within 3 seconds of damaging them grants Rengar a Trophy, once per unique champion and up to 5. An additional Trophy is made available through the event The Hunt is On! with the Head of Kha'Zix. Trophies grant bonus attack damage equal to % bonus AD.

Active: Rengar gains 40% bonus attack speed on his next two basic attacks within 3 seconds.

Ferocity Bonus: Bola Strike's damage is modified to deal 50 - 335 (based on level) (+ 80% bonus AD) physical damage. The target is root instead of slow.

Passive: Rengar also gains Unseen Predator while camouflage from any source.

Active: Rengar prowls for a duration, gaining bonus movement speed. After a 2-second delay, he also becomes camouflage and gains Unseen Predator.

During this time, Rengar will detect the nearest enemy champion in range, true sight and gaining sight of a 100-unit radius around them. Enemies detected are true sight for the remaining full duration.

The nearest detected enemy within 1600 range is also marked, alerting all of their allies within 1200 range about Rengar's presence.

Rengar's next basic attack within Rengar range against any enemy or with Unseen Predator to the marked enemy deals 100% AD bonus physical damage, then inflicts armor reduction for 4 seconds.
