Master Yi Adaptive TFT Set 18 is quickly becoming one of the most interesting reroll comps in the set. Instead of relying on expensive 4-cost or 5-cost carries, this comp focuses on 3-cost Master Yi. More importantly, it takes full advantage of the unique Adaptive trait.
With the right items, Master Yi can deal constant magic damage while healing himself throughout the fight. As a result, he can survive for a surprisingly long time while cutting through the enemy frontline.
However, there is one key rule you must follow: Master Yi’s AP needs to be higher than his AD. When this condition is met, Master Yi switches to his AP Adaptive form. Therefore, managing his stats correctly is the foundation of the entire comp.
In this guide, we will explain how to play Master Yi Adaptive TFT Set 18, including the best items, team composition, reroll strategy, Augments, and game plan for each stage.

Master Yi Adaptive TFT Set 18 Comp Overview
Master Yi is a 3-cost champion with the Spirit Blossom and Adaptive traits. Unlike many other carries, he does not use Mana to cast his ability.
Instead, after every three basic attacks, Master Yi triggers Double Strike. He attacks twice in quick succession. In addition, he gains movement speed after taking part in a takedown.
The Adaptive trait is what makes this champion especially interesting. His ability changes depending on whether his AD or AP is higher.
If his AD is higher, Master Yi enters his physical form. In this form, Double Strike grants additional attack speed. However, the damage output is not strong enough to make this version the main focus of the comp.
On the other hand, when his AP is higher than his AD, Double Strike deals significant bonus magic damage with each hit. Furthermore, Master Yi heals himself based on the damage he deals.
Because of this, AP Master Yi is the version you want to play. Not only does he deal much more magic damage, but he also becomes much harder to kill during extended fights.
Best Master Yi Adaptive Team Comp
At Level 8, the complete Master Yi Adaptive lineup includes:
- Yorick – Activates Spirit Blossom and provides early frontline.
- Vi – Main tank and an important 3-star target.
- Krug – Secondary tank that can hold extra defensive items.
- Kog’Maw – Secondary backline carry.
- Master Yi – Main carry and the highest 3-star priority.
- Gromp – Helps activate Adaptive.
- Sett – Adds extra frontline power.
- Nidalee – Helps complete 4 Adaptive.
Once the board is complete, the comp activates 4 Adaptive, 3 Spirit Blossom, 2 Primal, 2 Bruiser, 2 Juggernaut, and 1 Corrosion.
Kog’Maw is also an important part of the lineup. Thanks to Corrosion, he can reduce the enemy’s Armor and Magic Resist. Therefore, you do not always need to build another resistance-reduction item specifically for Master Yi.
Best Master Yi Items in TFT Set 18
The most important item for Master Yi Adaptive is Guinsoo’s Rageblade.
First, Guinsoo’s allows Master Yi to continuously stack Attack Speed. This is extremely important because more attacks mean more Double Strike activations.
More importantly, Guinsoo’s also provides AP. As a result, it becomes much easier to keep Master Yi’s AP above his AD and lock him into the stronger AP Adaptive form.
An ideal Master Yi build can look like this:
Guinsoo’s Rageblade + Rapid Firecannon + damage or defensive item
Among these options, Rapid Firecannon is especially powerful. The Artifact greatly increases Master Yi’s attack range. Consequently, you can place him much farther away from danger while he continues attacking throughout the fight.
Wit’s End is another excellent option. It adds extra magic damage to his basic attacks and works naturally with his high Attack Speed.
If you cannot find the perfect items, Titan’s Resolve, Hand of Justice, or Edge of Night are reasonable alternatives. However, you should always check Master Yi’s stats after equipping a new item.
The main rule remains simple:
AP > AD.
If Master Yi’s AD accidentally becomes higher than his AP, he will switch to his physical form. As a result, the overall power of the comp can drop significantly.

Best Items for Vi and Other Champions
While Master Yi is your main carry, 3-star Vi should usually be your second major priority.
Master Yi needs time to stack Guinsoo’s Rageblade and trigger Double Strike repeatedly. Therefore, your frontline needs to survive long enough for him to ramp up.
For this reason, your best defensive items should usually go to Vi.
Meanwhile, extra tank items can be placed on Krug or Sett. This gives the team a stronger frontline and creates even more time for Master Yi to deal damage.
If you have extra AP or Attack Speed items, Kog’Maw can become your secondary carry. Consequently, your board will not depend entirely on Master Yi during long late-game fights.
How to Play Master Yi Adaptive in the Early Game
During the early game, your main goal is to build a strong economy and prepare Master Yi’s core items.
If your opening board is weak, you can intentionally play for a losing streak. This allows you to build interest while also improving your priority during the carousel.
In particular, look for Recurve Bow and Needlessly Large Rod. These components are important because they allow you to complete Guinsoo’s Rageblade as early as possible.
However, avoid spending too much gold on rerolls at low levels.
Since Master Yi is a 3-cost champion, you will have much better odds of finding him later. Therefore, your priority should be reaching Level 7 with a healthy economy.

Mid Game: Slow Roll for 3-Star Master Yi
The mid game is the most important stage for this comp.
Ideally, you should reach Level 7 around Stage 3-5 or 4-1. Afterward, stabilize your board while trying to maintain 50 gold.
Once your economy is ready, start slow rolling above 50 gold.
Your two biggest targets are:
3-star Master Yi and 3-star Vi.
While rolling, you can also hold Kog’Maw or Krug if you naturally find many copies. However, do not destroy your economy just to upgrade every 3-cost champion.
Above all, Master Yi remains your number-one priority.
If you only need a few more copies of Master Yi and your HP is getting dangerously low, you can roll more aggressively. On the other hand, if you still have plenty of HP, continue slow rolling above 50 gold.
This approach gives you the best balance between board strength and economy.

When Should You Go Level 8?
Once you hit 3-star Master Yi, stop rolling and start rebuilding your economy.
Next, push toward Level 8. At this point, you can add Nidalee or Gromp to complete the 4 Adaptive breakpoint.
As a result, your overall board becomes much stronger. Master Yi already has enough damage to carry fights, while the additional unit improves your synergies and frontline.
Furthermore, if the game lasts long enough and you have plenty of gold, you can upgrade your secondary units or even push toward Level 9.
However, securing Master Yi 3-star should come first.
Best Augments for Master Yi Adaptive
Augments that provide Artifacts are extremely valuable for this composition. In particular, they can give you a chance to find Rapid Firecannon, which is one of Master Yi’s strongest items.
Additionally, economy and experience Augments are excellent choices.
They help you reach Level 7 faster while keeping enough gold for your slow-roll strategy. Therefore, they can make the entire transition into the mid game much smoother.
Another interesting option is Glass Cannon. This Augment increases damage but also causes the unit to lose health.
Normally, that downside can be dangerous. However, AP Master Yi has strong self-healing. Because of this, he can take advantage of the extra damage while partially covering the Augment’s weakness.
Master Yi Adaptive TFT Set 18 Tips
First of all, always check Master Yi’s AD and AP whenever you change his items. Even one item can change which Adaptive form he uses.
Therefore, do not simply equip an item because its individual stats look good.
Secondly, if you have Rapid Firecannon, position Master Yi in a safe area of the board. Thanks to the extra range, he can stay away from immediate danger while continuing to attack.
As a result, he gets more time to stack Guinsoo’s Rageblade and trigger Double Strike.
Positioning is especially important against teams that can quickly reach your backline. Therefore, scout other boards before each round and move Master Yi when necessary.
Finally, do not force this composition every game.
If several players are already holding Master Yi, reaching 3-star becomes much harder. In that situation, you may spend too much gold without finding the copies you need.
Instead, consider pivoting into another comp. This can often protect your placement and prevent an early elimination.
Conclusion
Master Yi Adaptive TFT Set 18 is a relatively simple reroll comp, yet it can still compete for high placements when you meet its key conditions.
Because Master Yi is only a 3-cost champion, you do not need to rush toward high levels to find an expensive carry. Instead, you can build your economy, reach Level 7, and slow roll for his 3-star upgrade.
Most importantly, remember the core formula:
Guinsoo’s Rageblade + AP higher than AD + 3-star Master Yi.
After that, build a durable frontline around Vi and eventually reach Level 8 to complete 4 Adaptive.
Moreover, if you find Rapid Firecannon, this can be an excellent signal to commit to the comp. The extra attack range gives Master Yi more space to stack Attack Speed, deal constant magic damage, and heal throughout the battle.
Overall, when played correctly, Master Yi Adaptive TFT Set 18 can become a powerful and frustrating reroll comp for opponents to deal with. Therefore, it is a strong option for players looking for a flexible 3-cost carry that can deal consistent damage while staying alive deep into each fight.
