Zac Build and Stats

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

The build tables come from ranked Solo/Duo games of Master+ players on the current patch. The calculator opens with Zac: load the most built items into it with one click, then change any item, the level or the rune shards.

Most Built Zac Items, Runes and Spells

We are still collecting Zac games for patch 26.20. The build tables appear once 20 games of Zac 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.

Zac Base Stats and Growth

Zac starts with 685 health, 60 attack damage, 33 armor and 32 magic resist, and reaches 2,538 health and 118 attack damage at level 18 without items. Zac's level 18 health ranks 24 of 173 champions, attack damage 62 and armor 15. Attack range is 175 (rank 87) and move speed 340 (rank 37).

Zac 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 Zac's stats at each level before items, runes and the kit.

Zac Attack Speed and Effective Health

Zac attacks 0.736 times per second at level 1 and 0.910 at level 18 without items, gaining 1.6% bonus attack speed per level. Bonus attack speed is multiplied by Zac's attack speed ratio of 0.638, so Zac needs about 328% bonus attack speed from items and runes at level 18 to reach the cap of 3.003 attacks per second.

With 2,538 health and 121 armor at level 18, Zac takes 5,619 physical damage before dying (effective health), and 4,235 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 Zac 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 Zac 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 Zac'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 Zac 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 Zac'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.
