Jayce Build, Runes and Counters — Top, Jungle and Mid · Patch 26.20

the Defender of Tomorrow

Patch 26.20 · Stats from the 26.18 Master+ sample (9,932 games).

Jayce, the Defender of Tomorrow, switches between a hammer and a cannon with Mercury Cannon / Mercury Hammer, so every one of his abilities has two versions. He is played in three roles in the Master+ count — Top most, then jungle, then Mid — his keystones are spread out with Stormraider's Surge ahead, and Youmuu's Ghostblade heads his usual build.

Counter plan — how to beat Jayce

  • Avoid extended fights — its sustain grows with every trade it survives

  • Close the gap early — it wins at range and at three items — neither before ten minutes

  • Punish the cooldown — Jayce is exposed while its rotation is down

  • Ward the flank — vision is what turns its best opening into a worse one

  • Respect the spike — Riot rates the kit 7/10, so a practised player gets more out of it than the average

Jayce balance history

Riot's notes from patch 25.S1.1 to 26.20 change Jayce in 6 patches. The latest is patch 26.14, published 2026-07-14.

  1. Patch 26.142026-07-14

    PHextech Capacitor

    • Bonus Move Speed40to30

    RMercury Hammer

    • Bonus Armor and Magic Resistance5 / 15 / 25 / 35 (+7.5% bonus Attack Damage)to5 / 12 / 19 / 26 (+7.5% bonus Attack Damage)
    Why, in Riot's words

    Jayce quickly climbed the ranks after our 26.03 adjustments and has stayed at the top of the pack. Additionally, he has become a fairly comfortable blind pick champ due to his Rune flexibility, and is the most picked top laner in higher ranks. Right now he's building like an assassin, but playing like a fighter, which we prefer to the tank Jayce era. These changes should tap down on his speediness and high durability while preserving what makes him fun.

  2. Patch 26.32026-02-03

    QTo the Skies!

    • Damage60 / 105 / 150 / 295 / 240 / 285 (+135% Bonus AD)to60 / 110 / 160 / 210 / 260 / 310 (+ 135% Bonus AD)

    • Monster bonus damage25to10

    RCannon Stance: Mercury Cannon

    • Armor/Magic Resistance Shred10 / 15 / 20 / 25%to20 / 25 / 30 / 35%
    Why, in Riot's words

    Jayce's build has bounced around a lot over time. He's been a tank, he's been (and currently is) a lethality burst mage, and he's been a fighter. We'd like if Jayce were an AD fighter, caring about both his damage output and durability to stick it out in melee once in a while. He's also still better in the jungle than in the top lane after last patch's nerf, so we're here to re-visit him. Ultimately our goals for Viktor's better half are to give him a viable fighter build and a viable but not overbearing jungle role. To achieve these goals, we're reducing his reliance on bonus AD and shifting power from his poke into his melee damage and follow-up.

  3. Patch 26.22026-01-21

    QTo the Skies / Shock Blast

    • Bonus Damage to Monsters 50to25
    Why, in Riot's words

    Jayce jungle (AKA Jungle Jayce) has become extremely popular and is also much too strong. One of those two things is awesome and the other isn’t. We’d like to retain JJ as a viable option in the jungle, but without him dominating the competition. So we’re delivering a light nerf that’s intended to bring him more in line with other junglers.

  4. Patch 25.232025-11-18

    QTo the Skies! (Hammer Stance)

    • Bonus Monster Damage0to50 flat bonus damage

    QShock Blast (Cannon Stance)

    • Bonus Monster Damage0to50 flat bonus damage
    Why, in Riot's words

    We think Jayce jungle is a bit of a longshot but there's a chance he's got a real player base in this new role, so we're delivering some buffs to make his first clear more comfortable and watching to see how many players are interested.

  5. Patch 25.182025-09-09

    QShock Blast (Cannon Stance)

    • Damage60 / 110 / 160 / 210 / 260 / 310to80 / 126 / 172 / 218 / 264 / 310
    Why, in Riot's words

    Piltover's poster boy hasn't been defending tomorrow very well lately, and has seen little presence in pro play despite the top lane meta being one he should thrive in. To help him out a bit we're going to give him a high skill skewed buff to make his shock blasts all the more... shocking.

  6. Patch 25.042025-02-19

    WHyper Charge

    • Set Attack Speed2.67to3.0
    Why, in Riot's words

    We've got a pretty straight forward change for Jayce this patch. Last patch when we raised the attack speed cap, we missed increasing his W to match, so we're back to right that wrong.

Playing against Jayce

  • If you see Jayce drop his Acceleration Gate, be careful, he is probably about to cast Shock Blast.

Jayce's story

Jayce Talis is a brilliant inventor who, along with his friend Viktor, made the first great discoveries in the field of hextech. Celebrated across Piltover, he tries to live up to his reputation as "the Man of Progress," but often struggles with the expectations placed upon him. Because of this, Jayce has begun to see the ways in which his invention has furthered the division between Piltover and Zaun—and armed with his hextech hammer, he stands ready to defend tomorrow.

Methodology

Data window
Preview sample — a one-time snapshot of 65,406 ranked games (Master+, EUW/KR/NA, patch 26.18), counted by GamGem while our Riot production key is under review. Figures will update daily once it is approved. Counted 26–27 Sept 2026; patches 26.18 (35,477) · 26.19 (18,580) · 26.17 (11,048) · 26.16 (293) · 26.15 (8); by server EUW 22,382 · KR 21,922 · NA 21,065 · EUNE 20 · TR 17. 642 games without a result — remakes ended by vote in their first minutes, and games recorded with no winner — were not counted.
Rank aggregation
Master, Grandmaster and Challenger, pooled — the three ladders the count read its players from. Splitting further leaves samples too small to separate a real effect from noise.
Role assignment
A champion is filed under every lane that holds at least a tenth of its counted games — the position the match itself reports, not the champion’s class. Its headline win rate is across all of them; each lane’s own win rate and games are counted too, and a lane’s tier list ranks by them.
Counters
The two champions in the same position on opposite teams, over that pairing’s own counted games — ranked on the edge pulled toward zero by its sample size, printed raw.
Minimum sample
None — no figure is hidden for being thin. Every rate prints its games, and the confidence band is its 95% margin: Very High within ±1.5 points, High ±2.5, Moderate ±3.1 (1,000 games), Low wider.
Why a build is not a cause
An item is counted when the match ENDS with it, so late items show long games and an item bought when already ahead shows games that were being won. Correlation is what a rate can show; it is not evidence that buying the item caused the win.
Where the numbers come from
Names, classes, abilities, items and runes are Riot Data Dragon. Win, pick and ban rates, builds, keystones, spells and matchups are counted by GamGem from Riot's ranked match records. An estimate, not a count: this panel is not in the preview sample, and is labelled so.
