Not Updated For Current Season

The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.



Offense: 21

Honor Guard

Defense: 5


Utility: 4



+ Great burst and AS steroid
+ Easy ganks from brush
+ Naturally tanky
+ Slow / Snare CC
+ Decent built in sustain
+ Stealth that revels enemy champions

- Easy to harass early game, especially by ranged champions
- Counter-jungled easily due to lack of escape
- Ultimate can be countered by Oracles


Ability Sequence
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

(Passive) - While in brush or stealth, Rengar will leap at the target when using his basicattack. Rengar builds 1 Ferocity with each ability he uses on enemies. When reaching 5 Ferocity, Rengar 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.


- Rengar 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!





Greater Quintesence of Armor Penetration


Greater Mark of Attack Damage x9 - Early attack damage will help you last hit minions and help you come out on top of any early fights.
Other Mark Options:
Greater Mark of Desolation - Another good choice for any AD champion. These will help you late game when enemies start to build up their armor.

Greater Seal of Armor x9 - Standard pick for almost all melee champions. It will help lower damage taken from most of the popular top lane champions.
Other Seal Options:
Greater Seal of Vitality - A good replacement if you plan on building like a bruiser rather than a fighter/assassin.

Greater Glyph of Scaling Magic Resist x9 - Another standard pick for almost every champion these days. This will help in late game when the enemy AP carry is dishing out a ton of damage.
Other Glyph Options:
Greater Glyph of Cooldown Reduction - Being able to use your abilities faster means you gain ferocity faster which can improve your damage output quite a bit.

Greater Quintessence of Armor Penetration x3 - Once again this will help early game with last hitting and trade offs. These can easily be changed for one of the options below.
Other Options for Quints:
Greater Quintessence of Movement Speed - Being able to keep up with a fleeing enemy helps Rengar utilize the attack speed boost from Savagery , and also helps you travel the map a bit faster.
Greater Quintessence of Health - I would only suggest using these if you are new to the champion and find yourself dying a lot early game. Rengar is easily harassed and these can help cushion the blow.



Ignite. Helps secure your kills and get the upper hand on healing enemies. Standard pick for most top lane champions.

Ghost. Great for escaping, but also very key to chasing. This will help you stay with them even after they Flash away.


Smite. Required for all junglers. Use this to not only clear the jungle, but as a way to secure/steal jungle mobs like Dragon and Baron.

Ghost. Once again, great for catching up with fleeing enemies even after they flash away. If you are worried about getting counter-jungled, you may want to replace this with Flash.


Flash. A decent replacement for Ghost as it will allow you to flash over walls in the jungle. It also allows you to overextend a bit more seeing as you can escape most ganks by hopping over a wall or out of reach.

Exhaust. Some people prefer this to Ignite . It is a solid choice and will give you the upper hand on 1v1 fights. This can also replace Ghost when jungling to help with ganks.

Heal. A decent choice if you are new to a champion, but you will be sacrificing your kill secure spell. Do not use this when jungling!


REMINDER: This is just one of many ways to build Rengar. I do not list a full 6 items here because a good player adjusts their build each game based on the type of enemies they face. To round out this build you will need to add 2 items from the Situational Items section. If you would like a example of a full build please refer to the Purchase Order from the Solo Top icon at the top of this guide.


Mercury's Treads

Standard boots for any champion that has to get within melee range. The CC reduction is priceless and the magic resist is just icing on the cake. You will see in the Situational Items section that these can often be replaced with Ninja Tabi when facing heavy AD enemies.

Bonetooth Necklace

This is a unique item that only Rengar can purchase. I find this item extremely worth getting and makes you feel like a real hunter! If you find yourself with this item late game and you haven't gotten at least 6 stacks you might want to think out selling it for another item.

Frozen Mallet

Grab this for the passive alone! Once you hit an enemy they will never get away and you will rip them apart with your high attack speed. The large boost to your HP and AD also help make this a core item.


The boost to AD and sustain from this item is too good to pass up on Rengar. Some even choose to build this before Frozen Mallet for extra killing power.


wriggle's latern

Mercury's Treads

Like I said in the section above, these are standard for most melee range champions and can be replaced with Ninja Tabi in certain situations.

Wriggle's Lantern

While Rengar doesn't need a ton of help in the sustain department thanks to Empowered Battle Roar , the passive on this item will speed up your jungle clear time. Don't forget to utilize the free ward!

Bonetooth Necklace

Rengar's signature item. As a jungler, you should be able to stack this item pretty high which makes it that much better of an item to have. The increased range on your passive leap with 9 trophies makes ganking that much easier.

Frozen Mallet

This item is too good to not use on Rengar. The perma-slow this item gives you is priceless and will help ganking that much easier.
