Full AP Rengar – A Complete Guide

In League of Legends, almost all champions are known to build Attack Damage or Ability Power. Only a handful of them can build both due to their abilities’ AP/AD ratios. Rengar happens to be one of those champions. He is known to build AD but you can also make him work by itemizing Ability Power on him. This, however, changes his playstyle significantly, so let’s look at Full AP Rengar in this guide.

Rengar is one of the most popular assassins in League of Legends. He is mainly played in the Jungle but you can occasionally see him in the Top Lane as well. Known for his ability to one-shot most targets with a quick combo, Rengar famously builds AD items that provide lethality and critical strike chance to get as much damage as possible.

It is the more popular way of playing him and has a higher win rate. AP Rengar on the other hand is a different approach to playing the champion. 

t is more often played in the Top Lane rather than Jungle. Instead of relying on Savagery (Q), most of your damage comes from Battle Roar (W), allowing you to approach skirmishes and team fights differently. P1Tony, a Master AP Rengar one-trick has said that playing AP Rengar is simply a more fun way to play him. It is an off-meta build

In short, it is an alternative way of playing Rengar, allowing yourself to adopt a different playstyle and approach to the champion.


For AP Rengar, the go-to keystone is First Strike. It provides extra burst damage that you benefit from as your goal is to burst down your targets and you can earn gold based on your damage. It is the most optimal keystone for AP Rengar in season 12. In combination with First Strike, you pick Magical Footwear, Future’s Market, and Cosmic Insight.

The secondary choice of runes for AP Rengar is very similar to the primary AD Rengar runes. You opt for Electrocute to give you maximum burst damage over your short combos. It is picked in combination with Sudden Impact, Eyeball Collection, and Ultimate Hunter / Treasure Hunter.


Although you still start with a Doran’s Blade or Doran’s Shield, Rengar’s build completely changes after the starting item. The recommended build for AP Rengar is as follows:

Lich Bane, Hextech Rocketbelt, Rabadon’s Deathcap, Void Staff, Hullbreaker, Sorcerer’s Shoes.

The build may change depending on the game, allowing you to potentially go Zhonya’s Hourglass or Banshee’s Veil. As the game progresses, your first recall should get you a Hextech Alternator which builds into a Hextech Rocketbelt as your first item.

After that, you can opt for Sorcerer’s Shoes and Lich Bane followed by a Rabadon’s Deathcap. You can pick up a Dark Seal if you have a lead on your enemies, building a Void Staff next. Finishing the build off with a situational item, you can build a Hullbreaker for split pushing as Rengar but you can choose other items instead depending on the game state.

The magic penetration from Sorcerer’s Shoes, combined with that from Hextech Rocketbelt, is an irreplaceable choice. Lich Bane provides an AP-scaling empowered auto-attack as well as 10% extra movement speed, allowing you to possibly rush this item before getting boots.

Your next item is a big power-spike, Rabadon’s Deathcap. It boosts your AP to over 500 and makes you much stronger. A void staff may be bought before a Rabadon’s Deathcap, depending on the enemy team’s itemization. 

Skill Order

You level up Q, W, and E at levels 1, 2, and 3 respectively as you would on AD Rengar but instead of maxing Savagery (Q) first to level 5, you max Battle Roar (W) due to the Ability Power ratio on the ability. This allows you to deal damage on AoE instead of single-target, giving Rengar great wave-clear in the lane. Additionally, you level up Thrill of the Hunt (R) at levels 6, 11, and 16.

You can max E before Q due to the Bola Strike (E)’s base damage scaling higher than that of Q which is better for you as a Full AP Rengar. Another thing is that the 90% slow on Bola Strike at level 5 is extremely useful, making E a better choice to max over Q.

AP or AD, Rengar is still very much an assassin. You can still jump on the enemy and expect to one-shot them but with a different approach. You rely on your W to do most of your damage and healing. AP Rengar pressures throughout the lane.

He can utilize the bushes to his advantage and win any 1v1 early on. He deals a surprising amount of damage at all stages of the lane, playing in a poke style.

Utilizing the first 14 minutes of the game to his advantage, AP Rengar with Sheen is great at taking tower plates. After the lane, you can snowball by getting kills elsewhere but the focus stays on getting side-lane farm and towers.

There are two ways you can play team fights as AP Rengar. You can simply assassinate the enemy ADC, turning the fight to a 5v4. This significantly increases your chances of winning the team fight. The other way is the ideal way to teamfight on AP Rengar.

As you deal a ton of AoE damage, you are to engage on the enemies and deal damage to them using your W. This is especially strong because of your AP strength.



AP Rengar is more useful in team fights thanks to his AoE damage from Battle Roar (W). He can provide more for his team compared to AD Rengar whose job is purely to assassinate the enemy ADC.

Extended Leap Range

Rengar’s passive Unseen Predator gives him a large amount of range on his basic attacks from a bush, allowing him to leap to any attackable target. Combined with this passive, his leap range further with Hextech Protobelt, making him even more lethal from any bush. 

Faster Combo

Rengar is known for outputting damage based on his combos. An AD Rengar combo goes as follows:

Q > E > W > Empowered Q

His AP combo is faster than his AD combo. It goes as follows:

Q > E > W > Rocket Belt (item active) > Empowered W

Better Wave-Clear

Battle Roar allows Rengar not only to heal back 50% of any post-mitigation damage that he has taken in the previous 1.5 seconds but also deals magic damage to nearby enemies or targets.

As this ability scales with AP, your AoE damage increases and as AoE abilities are great for wave-clearing, you ultimately gain better wave clear.

Falling Behind

Once you are behind in terms of gold and XP, it is really difficult to regain your ground and the game becomes significantly difficult.

The “Toll Build”

AP Rengar is often considered a troll build, therefore, you are likely to get flamed by your teammates or considered a troll in their team.

Should You Try AP Rengar?

Yes. We recommend testing out this build in one of your games to get a feel for it. It brings a unique playstyle to the champion we know as a crit one-shot machine, making him stronger in lane.

The superior wave-clear, AoE damage, and absurd healing that AP Rengar brings is certainly a fun build to test out. Who knows, maybe you will enjoy it more than the AD build.

Final Thoughts

Most people consider AP Rengar to be a troll build but P1Tony has proven that you can use it to reach any rank that you desire. With that being said, note that AD is still a better and more reliable build on Rengar.
