Rengar

Innate: Rengar generates 1 Ferocity upon casting a basic ability or using Savagery first attack. At 4 Ferocity, his next basic ability consumes them all to become empowered with an additional effect and grant him an additional cast along with % bonus movement speed for 1.5 seconds. All Ferocity is lost after 10 seconds of being out of 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, attacking the target upon arrival and landing closer than his normal melee range. Unseen Predator will generate 1 Ferocity on-hit if none of his current Ferocity was generated this way. Ferocity generated by Unseen Predator has a distinct color. Rengar can cast any of his abilities during the dash.

Active: Rengar empowers his next two basic attacks within 3 seconds to gain 40% bonus attack speed. His first attack has an uncancellable windup, gains 25 bonus range, and deals bonus physical damage, reduced by 40% against structures. The attack will critically strike for AD bonus physical damage.

Ferocity Bonus: Savagery's damage is modified. Rengar gains % bonus attack speed for 5 seconds.

Savagery basic attack reset Rengar's basic attack timer.

Passive: Rengar stores 50% of the post-mitigation damage he has taken in the last 1.5 seconds as grey health on his health bar, increased to 100% of damage taken from monsters.

Active: Rengar roars, dealing magic damage to nearby enemies and 65 to 130% bonus magic damage to monsters, and consuming his grey health to heal for the same amount.

Ferocity Bonus: Battle Roar's damage is modified. Rengar cleanse himself from all crowd control.

Active: Rengar throws a bola in the target direction that deals physical damage to the first enemy hit and slow them for 1.75 seconds, as well as true sight them for 2 seconds and granting sight of a 150-unit radius around them for the same duration.

Ferocity Bonus: Bola Strike's damage is modified. 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.

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.
