Corki splash art for this Corki guide

Corki plays the mid lane as the Daring Bombardier mixed-damage ADC-mage on patch 26.22. Phosphorus Bomb drops a bomb at a target location (reveals enemies hit and reduces their vision range). Valkyrie flies Corki to a target direction (leaves a flame trail that damages enemies walking through). Gatling Gun channels a cone that damages and shreds enemy Armor/MR. Missile Barrage fires missiles at a target direction (consumes “Big One” missiles for bonus damage at every 4 missile cast).

Corki’s Data Dragon file lists him under Marksman and Mage tags, 6 out of 10 difficulty rating, 550 ranged auto range, and Mana as the pool. His Hextech Munitions passive deals bonus magic damage on basic autos; the passive compounds with his AP ratios on Missile Barrage.

Abilities and role

Corki’s lane plan on patch 26.22 is the Mid lane solo-queue mixed-damage pick. The Hextech Munitions passive plus Missile Barrage barrages shred both tanks and squishies through mixed-damage output; his Valkyrie flame trail covers escape vectors.

Hextech Munitions (Passive)

Corki’s basic autos deal bonus magic damage. The passive compounds with his AP ratios on Missile Barrage. For what it’s worth, Hextech Munitions is Corki’s primary mixed-damage engine; a committed auto cycle during all-in trades deals both AD and magic damage.

Phosphorus Bomb (Q)

Corki drops a bomb at a target location. Enemies hit are revealed and have their vision range reduced. 9 to 7 second cooldown, 60 mana. The Q is Corki’s primary scouting-plus-damage ability during the laning phase; a committed Phosphorus Bomb on the enemy mid-laner reveals their position for the all-in Missile Barrage barrage.

Valkyrie (W)

Corki flies to a target direction. Leaves a flame trail that damages enemies walking through. 20 to 12 second cooldown, 60 mana. The W is Corki’s primary mobility button; a committed Valkyrie flight across a jungle wall covers map traversal faster than most mid-laners.

Gatling Gun (E)

Corki channels a cone that damages and shreds enemy Armor/MR for 4 seconds. 12 second cooldown, 50 mana. The E is Corki’s primary trading tool; a committed Gatling Gun cone during an all-in trade shreds the enemy mid-laner’s Armor/MR for the all-in Missile Barrage barrage.

Missile Barrage (R)

Corki fires missiles at a target direction. Every 4 missiles cast, Corki fires a “Big One” missile for bonus damage. 2 second cooldown (gated by missile stacks), 20 mana. The R is Corki’s primary long-range damage ability; a committed Missile Barrage spam cycle during all-in teamfights deals massive sustained AoE damage.

Build and item spikes

Corki’s lane start pairs Doran’s Blade with a Potion. First item is Trinity Force for the Attack Speed buff, Spellblade proc on committed Missile Barrage missiles, and the sticky Rage during all-in trades.

Slot two picks Essence Reaver for the mana sustain plus the Spellblade proc that pays off every missile cast cycle. Slot three flexes to Rapid Firecannon for the burst range on committed Phosphorus Bomb pokes, Infinity Edge for the crit damage multiplier on all-in Big One missiles, or Shadowflame for the magic penetration on all-in Missile Barrage AP triggers. Full first-through-sixth-item path lives on our LoL items database.

How to play by game stage

Pre-6 Corki plays Phosphorus Bomb pokes on the enemy mid-laner during cannon-wave resets. Weave Gatling Gun cone shred during committed trade windows. First solo kill opens at level 6 with Phosphorus Bomb reveal + Missile Barrage barrage + Big One missile execute.

Mid game (7-13): R Missile Barrage during all-in 2v2 skirmishes stacks Big One missiles for an all-in burst payoff.

Late game (14+): Corki fights with the ally frontline. Missile Barrage spam against grouped enemies at the Baron pit lands massive sustained AoE damage. A Shadowflame fourth item amps the magic penetration on committed Missile Barrage AP triggers.

Who counters Corki

Corki’s weakness list on 26.22 picks out specific mids. Burst assassins who commit before Valkyrie can activate (Zed R, LeBlanc, Katarina roam). Hard-engage junglers who dive during Corki’s slow Valkyrie cooldown windows (Jarvan E-Q flag, Vi R, Nocturne R). Mobile ADCs (Ezreal, Tristana, Kai’Sa) who dash out of Gatling Gun cone range.

  • Burst assassins: Zed, LeBlanc, Katarina. Each commit before Valkyrie activates.
  • Dive junglers: Jarvan IV, Vi, Nocturne. Each commit a gank during Corki’s slow Valkyrie cooldown.
  • Mobile ADCs: Ezreal, Tristana, Kai’Sa. Each dash out of Gatling Gun cone range.

ARAM notes

On Howling Abyss, Corki’s kit shines (stacked bridge fights amp his Missile Barrage spam on grouped enemies plus the Big One missile cycle). Trinity Force opens for the Attack Speed on committed Missile Barrage missiles across the bridge. Essence Reaver arrives second for the mana sustain plus Spellblade proc. Rapid Firecannon lands third for the burst range on all-in Phosphorus Bomb pokes. R Missile Barrage against grouped enemies at the bridge choke lands sustained AoE damage plus all-in Big One missile executes.

Corki ARAM pairs well with hard-engage ally supports (Leona, Nautilus, Rell) whose CC chain pins enemies long enough for the committed Missile Barrage barrage. The Corki ARAM build page carries the full item path and matchup table.

FAQ

Is Corki easy to learn?

6/10, mostly from Package timing. Corki without Package is a weak mid-ADC with poor wave clear; Corki with Package is a backline-sniping monster. New players stack autos on the enemy support in lane (wrong — his damage comes from Q Phosphorus Bomb into W Valkyrie dash). Mains time Package pickups (every 4 minutes) with jungle camp spawns for a free rotation gank. His R has reduced range at close distance — use it as a long-range sniper, not a self-defense button.
