Corki Build and Runes — Bot Lane, Mid and Top · Patch 26.20

the Daring Bombardier

Patch 26.20 · Stats from the 26.18 Master+ sample (3,021 games).

Corki, the Daring Bombardier, deals part of every attack as true damage through Hextech Munitions and stores missiles for Missile Barrage, every third one a Big One. Master+ players took him to the bot lane in most counted games, nearly always on Conqueror, and his usual build is Trinity Force, Manamune and The Collector.

Counter plan — how to beat Corki

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

  • Dodge the primary — its rotation is one skillshot; sidestep it and the rest is chip

  • Punish the cooldown — Corki 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 6/10, so a practised player gets more out of it than the average

Corki balance history

Riot's notes from patch 25.S1.1 to 26.20 change Corki in 5 patches. The latest is patch 26.14, published 2026-07-14.

  1. Patch 26.142026-07-14

    Base Stats

    • Attack Damage Growth2to2.5

    RMissile Barrage

    • Remaining Recharge Time Reduction from Autos2 - 4 seconds (based on critical strike chance)to2 - 6 seconds
    Why, in Riot's words

    Everyone's favorite incoherent aviator is having trouble taking off in bot lane. So, we want to give a little more firepower to Corki's sorties later in the game, and really enhance his spell-weaving missile firing fantasy!

  2. Patch 26.12026-01-07

    WValkyrie

    • Damage per second40 / 55 / 70 / 85 / 100 (+40% bonus AD) (+ 30% AP)to30 / 45 / 60 / 75 / 90 (+40% bonus AD) (+ 30% AP)
    Why, in Riot's words

    Corki isn't particularly strong at the moment, so while this is a nerf on paper, we expect Corki will be overall stronger at the start of the season. This nerf is aimed at weakening his ability to crush a minion wave right before a Recall.

  3. Patch 25.192025-09-23

    QPhosphorus Bomb

    • Damage70 / 115 / 160 / 205 / 250 (+130% AD)to60 / 105 / 150 / 195 / 240 (+ 125% AD)
    Why, in Riot's words

    Corki is becoming a little stale in pro play so we’re delivering a nerf to open up the bot lane metagame for Worlds this year. We’re hoping to pro-skew this nerf by removing some of his trivial wave pushing.

  4. Patch 25.152025-07-29

    QPhosphorous Bomb

    • Damage70 / 120 / 170 / 220 / 270 (+ 120% bonus AD) (+ 100% AP)to70 / 115 / 160 / 205 / 250 (+ 130% bonus AD) (+ 100% AP)

    RMissile Barrage

    • Damage90 / 170 / 250 (+ 80% bonus AD)to90 / 170 / 250 (+ 85% bonus AD)
    Why, in Riot's words

    We’re delivering some adjustments to Corki with the intent of pushing him toward squishier high-AD builds and slightly toning down his extremely potent late-laning phase spike while still maintaining his presence as a strong laner.

  5. Patch 25.062025-03-18

    Base Stats

    • Base Armor30to27
    Why, in Riot's words

    Corki is a little overbearing at higher skill brackets in the bot lane, so we're bringing down a little of his early bullying power. He already falls off a cliff late game, so we're skewing these nerfs toward the early game, hence a base armor reduction.

Riot's tips for Corki

Playing Corki

  • Phosphorus Bomb can be used to reveal enemy units that might be hiding in a nearby patch of brush.
  • Valkyrie can be used defensively as well, so try using it for a quick escape.
  • Corki can continue to attack while using Gatling Gun. Maximizing Gatling Gun is key to mastering Corki.

Playing against Corki

  • Watch out for Corki's Missile Barrage. They deal splash damage, so you can get hit even when hiding behind minions.
  • Corki is vulnerable after he uses his Valkyrie or Special Delivery, so try switching focus to him if he uses them to enter a fight.

Corki's story

The yordle pilot Corki loves two things above all others: flying, and his glamorous mustache... though not necessarily in that order. After leaving Bandle City, he settled in Piltover and fell in love with the wondrous machines he found there. He dedicated himself to the development of flying contraptions, leading an aerial defense force of seasoned veterans known as the Screaming Yipsnakes. Calm under fire, Corki patrols the skies around his adopted home, and has never encountered a problem that a good missile barrage couldn't solve.

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.
