Master Yi Build and Stats
Master+ builds and stats per level, patch 26.20. What Master, Grandmaster and Challenger players build on Master Yi this patch, Master Yi's stats at every level, and a calculator to try any build before you play it.

Most Built Master Yi Items, Runes and Spells
We are still collecting Master Yi games for patch 26.20. The build tables appear once 20 games of Master Yi in one position have been read; until then, the stats below and the calculator work as usual.
These are counts, not advice: a choice that many players make is a safe starting point, and the win rate shows how those games ended. Items and runes that only fit some matchups show lower pick rates, so read them with the game in front of you.

Master Yi Stats at Every Level (1 to 18)
Stats do not grow in a straight line: each level adds a little more than the one before, following Riot's formula base + growth × (level - 1) × (0.7025 + 0.0175 × (level - 1)). The table gives Master Yi's stats at each level before items, runes and the kit.
| Level | Health | Mana | Attack damage | Armor | Magic resist | Attack speed | Health regen per 5 s |
|---|---|---|---|---|---|---|---|
| 1 | 640 | 251 | 65 | 33 | 32 | 0.679 | 7.5 |

Master Yi Attack Speed and Effective Health
Master Yi attacks 0.679 times per second at level 1 and 0.968 at level 18 without items, gaining 2.5% bonus attack speed per level. Bonus attack speed is multiplied by Master Yi's attack speed ratio of 0.679, so Master Yi needs about 300% bonus attack speed from items and runes at level 18 to reach the cap of 3.003 attacks per second.
With 2,425 health and 118 armor at level 18, Master Yi takes 5,286 physical damage before dying (effective health), and 4,046 magic damage with 67 magic resist. Every item that adds health, armor or magic resist raises these numbers in the calculator above.
How to Use the Master Yi Build Calculator
- Click "Load this build into the calculator" under a position's tables to start from the most built items, or fill the six slots yourself.
- Move the level slider to see Master Yi at any level from 1 to 18.
- Choose one rune shard per row; adaptive force turns into attack damage or ability power from your items.
- Switch to Build B to compare two builds; the sheet shows both and the difference.
- Copy the link to share the build: it opens on this page with the same items, level and shards.
The calculator adds the stats items and shards give. Item passives, stacks and Master Yi's own abilities are not counted, so in-game numbers can be higher. The LoL item builder guide explains armor, penetration, ability haste and gold efficiency.
Where the Master Yi Build Data Comes From
Every minute we read the ranked Solo/Duo match history of a random Master, Grandmaster or Challenger player through the Riot Games API, taking turns between the 15 servers, and keep what each of the ten players ended the game with: final items, boots, runes, summoner spells, position and the result. Remakes and early surrenders are left out.
- Finished items are counted once per game; the three-item core is the first three finished items in the player's inventory.
- Pick rate is the share of Master Yi's games in that position with the choice; win rate is the share of those games won.
- Games are grouped by patch: a new patch starts a new count, and older patches are dropped after four weeks.
- Lobbies are those of Master+ players, so most of the other nine players are high Diamond or above.
