Welcome to my Rengar guide! Here you will find a guide on how to hunt your prey with the savage Rengar!

Rengar is a melee fighter who excels in both top lane and the jungle. With the help of his abilities and his unique resource called Ferocity, Rengar is sure to add plenty of his enemies heads to his trophy collection.

I started this guide off with a lot of basic information about the champion because I want my readers to understand the champion before getting into details like runes and item builds.

Thank you to everyone who supports and votes for this guide!!!!

Lore - Rengar The Pridestalker

On every wall of his den, the trophy hunter Rengar mounts the heads, horns, claws, and fangs of the most lethal creatures in Valoran. Though his collection is extensive, he remains unsatisfied, tirelessly seeking greater game. He takes time with every kill, studying his prey, learning, and preparing himself for the next encounter with the one monster he never managed to defeat.

Rengar never knew his real parents, but was raised by a human who was revered as a legendary hunter. He was an ideal pupil, intently absorbing the lessons of his father, and improving them with his uncanny feral instincts. Before his mane had fully grown, Rengar set off on his own and claimed a wide territory for himself. Along its perimeter, he mounted the skulls of his slain prey - a warning to would-be aggressors. He thought undisputed reign of a region would fulfill him, but instead, he grew restless. No beasts in his domain proved challenging prey, and without formidable adversaries to push his limits, Rengar's spirit waned. He feared that no worthwhile game remained, that he would never again feel the thrill of the hunt. Just when things seemed their bleakest, he encountered the monster. It was a disturbing, alien thing, distinctly out of place in his world. It bore huge scything claws and devoured any animal that strayed across its path. Overzealous at the prospect of a challenge, Rengar ambushed the monster in haste. It far outclassed anything he'd hunted before. Their fight was savage, and each suffered crippling wounds. Rengar lost an eye, but the most grievous blow was to his pride. He had never before failed to make the kill. Worse yet, the severity of his injuries forced him to retreat. Over the following days, he hovered on the threshold between life and death. He was wracked with pain, but beneath it, he felt a glimmer of joy. The hunt was on. If such powerful beings existed in the world, he would find them, and stack their heads high. The monster, however, was a kill he wanted to savor. On his den's largest wall, he reserves a space for the beast's head, a trophy he swears will one day be the centerpiece of his collection.

"Prey on the weak and you will survive, prey on the strong and you will live." -Rengar

Unseen Predator (Passive) - While in brush or stealth, Rengar will leap at the target when using his basic attack. Rengar builds 1 Ferocity with each ability he uses on enemies. When reaching 5 Ferocity, Rengar's next ability becomes empowered, granting it a bonus effect.
Range: 600 or 750 with 9 trophies on Bonetooth Necklace

Unseen Predator has no cooldown and the leap can be used repetitively. For example, when chasing through brush, Rengar can continually leap onto his target. The buff will also last for ~.5 second after leaving brush or stealth. Upon reaching 5 Ferocity all of Rengar's empowered abilities become available for use. Note that his cooldowns are not reset. After Rengar consumes his Ferocity, all of his abilities resume what remains of their cooldowns.

Savagery - Rengar's next basic attack deals bonus damage and grants him increased attack speed for 4 seconds.
Cost: None
Cooldown: 8 / 7.5 / 7 / 6.5 / 6 seconds
Physical Damage: 30 / 60 / 90 / 120 / 150 (+1.0 per attack damage)
Attack Speed Bonus: 30 / 35 / 40 / 45 / 50 %

Empowered Savagery - Savagery deals bonus damage equal to 150% of Rengar's attack damage, and the Attack Speed bonus is doubled.
Cost: 5 Ferocity
Cooldown: None
Physical Damage: 30 / 60 / 90 / 120 / 150 (+2 per attack damage)
Attack Speed Bonus: 60 / 70 / 80 / 90 / 100 %

Savagery is your main damage ability and Empowered Savagery ends up doing a ton of burst damage and a lot of sustained damage through the attack speed boost. This ability will also reset Rengar's attack timer so landing an auto-attack before using it will maximize the damage. Also, the attack speed buff from both Savagery and Empowered Savagery stack, so using them back to back is encouraged.

Battle Roar - Rengar lets out a battle roar, damaging enemies and gaining bonus armor and magic resist for 3 seconds.
Cost: None
Cooldown: 15 / 14 / 13 / 12 / 11 seconds
Magic Damage: 50 / 80 / 110 / 140 / 170 (+0.8 per ability power)
Bonus Armor & Magic Resist: 15 / 22 / 29 / 36 / 43

Empowered Battle Roar - Battle Roar also heals Rengar for 40 (+20*level).
Cost: 5 Ferocity
Cooldown: None
Magic Damage: 50 / 80 / 110 / 140 / 170 (+0.8 per ability power)
Bonus Armor & Magic Resist: 15 / 22 / 29 / 36 / 43
Maximum amount healed at level 18: 400

Battle Roar helps you stay tanky in fights without having to build a lot of defensive items. Rengar gets his sustain for Empowered Battle Roar which will heal him even if the ability does not hit an enemy. These two versions of the ability will not cause the armor and magic resist to stack, but will refresh the duration.

Bola Strike - Rengar throws a bola at his target, slowing them for 2.5 seconds. The slow decays over the duration.
Cost: None
Cooldown: 12 / 11 / 10 / 9 / 8 seconds
Physical Damage: 60 / 105 / 150 / 195 / 240 (+0.7 per bonus attack damage)
Slow: 50 / 55 / 60 / 65 / 70 %

Empowered Bola Strike - Bola Strike initially roots his target for 1 second. The slow is applied in full after the 1 second, and decays over the remaining 1.5 seconds. Crowd control reduction will reduce each duration separately.
Cost: 5 Ferocity
Cooldown: None
Physical Damage: 60 / 105 / 150 / 195 / 240 (+0.7 per bonus attack damage)
Slow: 50 / 55 / 60 / 65 / 70 %

Bola Strike is Rengar's only CC ability. This is a target ability and applies full on-hit effects such as the ranged slow from Frozen Mallet. This ability can be priceless during ganks, especially if Empowered Bola Strike is used to snare the enemy.

Thrill of the Hunt (Ultimate) - Rengar activates his predatory instincts, stealthing after 1 second and revealing all enemy Champions in a large radius around him. He gains movement speed and generates 1 Ferocity per 0.75s while stealthed. Lasts 7 seconds or until he uses an ability.
Cost: None
Vision Radius: 2000 / 3000 / 4000
Cooldown: 140 / 105 / 70 seconds
Movement Speed Bonus: 20 / 25 / 30 %

Thrill of the Hunt is what makes jungling on Rengar so attractive. The real power behind this ability is the vision it provides. It allows you and your team to see all champions within the vision radius, including champions inside of brush and other stealth champions. This ability can also be used as a great escape for when things go bad or to just get focus off of you in a team fight. Also, activating Savagery will not break stealth. Knowing when to use this ability will separate the good Rengar players from the great. NOTE: The fade time on this ability is now 1 second instead of .75 and taking any damage, pushes the fade time another 1 second (up to 3 seconds). Using this ability as an escape tool is not as reliable as before!
