Adaptor Rengar Team Comp
The main units for this composition are:
- Rengar – Main carry
- Master Yi – Secondary carry
- Vi – Main tank
- Yorick – Frontline
- Krug – Frontline
- Kog’Maw – Extra damage
- Nidalee – Support
- Sett – Blossom support
Together, these units activate several useful traits.
The Adaptor trait is especially important. Adaptor champions can change their ability scaling based on their stats. Therefore, item choices can have a major impact on their performance.
Moreover, the composition works best as a Level 7 reroll comp. Instead of rushing Level 8, you should spend your gold on upgrading the core units first.
Why Play Adaptor Rengar?
First of all, Adaptor Rengar has two strong carries.
Rengar is great at attacking vulnerable enemy units. He can jump toward the backline and quickly pressure enemy carries.
Meanwhile, Master Yi is excellent in longer fights. He can continue dealing damage while your frontline absorbs enemy attacks.
Furthermore, both carries can use similar items. Because of this, your item choices are more flexible.
The team also has a reliable frontline. Vi can absorb damage at the start of combat. At the same time, Yorick and Krug provide additional durability.
Most importantly, the comp has strong reroll potential. Once you reach Level 7, you can search for several 3-star units.
Best Items for Rengar
Rengar is one of your main win conditions. Therefore, he should receive some of your best offensive items.
The recommended items are:
- Guinsoo’s Rageblade
- Edge of Night
- Titan’s Resolve
First, Guinsoo’s Rageblade helps Rengar become stronger during longer fights.
Next, Edge of Night provides valuable protection. This is especially useful because Rengar dives into the enemy team.
Finally, Titan’s Resolve gives him more power during extended combat.
However, do not wait too long for perfect items. Instead, use your components efficiently and keep your economy healthy.

Best Items for Master Yi
Master Yi is your second major carry. Therefore, he can also use powerful offensive items.
Good options include:
- Guinsoo’s Rageblade
- Edge of Night
- Titan’s Resolve
Fortunately, these items also work well on Rengar. As a result, you can remain flexible throughout the game. For example, if Rengar reaches 3 stars first, give him your strongest items. On the other hand, if Master Yi gets upgraded first, shift your items toward him.
This flexibility is one of the biggest advantages of the composition.
Best Items for Vi
Next, you need to build a strong frontline.
Vi is the preferred main tank, so give her defensive items whenever possible.
Recommended choices include:
- Gargoyle Stoneplate
- Warmog’s Armor
- Evenshroud
First, Gargoyle Stoneplate helps Vi survive when several enemies attack her. Meanwhile, Warmog’s Armor gives her a large amount of health. Therefore, she can stay in combat longer.
Finally, Evenshroud adds useful frontline utility. As a result, Vi can buy enough time for Rengar and Master Yi to eliminate enemy carries.
Early Game Strategy
During Stage 2, your main goal is to protect your HP while building your economy. Therefore, avoid unnecessary rolls.
Instead, build the strongest temporary board you can. If you find Rengar early, use him as your main damage dealer. You can also give him your future carry items.
At the same time, look for Blossom units. A strong Blossom opener can help you win early fights. Moreover, it can give you a smoother transition into the mid game.
However, do not force the final composition too early. Keep strong temporary units when they give you more combat power.
Most importantly, save your gold. You will need a healthy economy when you reach Level 7.

Stage 3 Strategy
During Stage 3, start moving toward your core composition.
You should look for:
- Rengar
- Master Yi
- Vi
- Yorick
- Kog’Maw
- Nidalee
- Krug
At the same time, begin completing your carry items.
If your current board is already strong, you do not need to roll heavily. Instead, keep your economy growing.
Furthermore, watch the other players in the lobby. If several players are holding Rengar or Master Yi, your reroll chances may become worse.
Therefore, scouting can help you decide whether to commit fully to the comp.

Level 7 Reroll Strategy
Level 7 is the most important stage for Adaptor Rengar.
Once you reach Level 7, start rolling to stabilize your board.
Your first targets should be:
- Rengar 2-star
- Master Yi 2-star
- Vi 2-star
- Yorick 2-star
- Other core units
However, do not spend every piece of gold immediately.
First, make your board strong enough to survive. Then, rebuild your economy.
Afterward, use a slow-roll strategy. Keep a healthy amount of gold and use the excess to search for your 3-star units.
Your main targets are:
- Rengar 3-star
- Master Yi 3-star
- Vi 3-star
Rengar and Master Yi should have the highest priority. Meanwhile, Vi becomes an excellent upgrade if you find many copies.
Once your main carries reach 3 stars, you can consider leveling higher. Then, add another useful unit to improve your traits or combat power.

Best Augments for Adaptor Rengar
Augment choices should depend on your board. Nevertheless, some options are particularly useful.
Economy Augments
Economy Augments are strong because this composition wants to slow roll.
More gold gives you more chances to find Rengar, Master Yi, and Vi. Therefore, these Augments are especially useful when you are close to several upgrades.
Item Augments
Item Augments are also valuable.
They can help you complete your core items faster. Furthermore, powerful Artifact items can give your carries a major boost.
Combat Augments
Finally, Combat Augments are useful when your economy is already strong.
If you already have enough gold, additional combat power can help you win fights while you search for your 3-star units.
Therefore, try to balance economy and combat power.
Positioning Guide
Positioning is extremely important for this composition.
First, place Rengar on the side where he can reach the enemy backline. His goal is to attack a vulnerable carry as quickly as possible. Meanwhile, keep Master Yi behind your frontline. This allows him to deal damage without taking too much damage early.
Next, place Vi near the front. She needs to absorb enemy attacks and protect your carries. Yorick and Krug can stand nearby. Together, they create a stronger defensive line.
Finally, keep Kog’Maw and Nidalee in safer backline positions. However, do not use the same positioning every round. Instead, scout your opponents and adjust your units.
For example, if an enemy carry moves to the opposite side, move Rengar as well. Consequently, he has a better chance of reaching the correct target.
Strengths of Adaptor Rengar
Two Strong Carries
First, Rengar and Master Yi can both become 3-star win conditions. Therefore, the team has strong late-game damage.
Flexible Items
Both carries can use similar items. As a result, you have more freedom when managing components.
Strong Backline Pressure
Rengar can quickly reach fragile enemy carries. This makes him especially dangerous against backline-heavy teams.
Strong Reroll Potential
Because the comp focuses on 3-cost units, Level 7 is an effective point to search for upgrades.
Reliable Frontline
Finally, Vi, Yorick, and Krug can protect your damage dealers. This gives your carries more time to work.
Weaknesses of Adaptor Rengar
Despite its strengths, the composition has several weaknesses.
It Needs Upgrades
The team becomes much stronger after Rengar and Master Yi reach 3 stars. Therefore, weak rolls can hurt your final placement.
It Can Be Contested
Other players may also use Rengar or Master Yi. Consequently, you should scout before committing heavily.
Level 7 Is Important
Your Level 7 roll needs to stabilize the board. If you fail to find your key units, you may lose too much HP.
Positioning Matters
Finally, Rengar can lose a fight if he jumps onto the wrong target. Therefore, scouting and repositioning are essential.
