Tier C ADC

Corki, the Daring Bombardier, is a marksman and mage champion of medium difficulty. Across our 462 analysed ranked games, Corki is mostly played as ADC (74% of its games), and more rarely in Mid (17%), with a 43.7% win rate in that role: tier C among ADC champions (#36 of 36, ranked by win rate). Corki's damage is mostly physical (66%): armor is the best defensive answer against this champion. 14% of that damage is true damage and therefore ignores resistances. Win rate varies with game length: 49.6% in short games (under 25 min, 129 games) versus 35.0% in long games (over 35 min).

Averages measured over 343 ADC games played with Corki, from our ranked Solo/Duo data collection.

Combos and how to play

Corki is a mixed-damage marksman-mage: his attacks deal bonus true damage. Phosphorus Bomb reveals, Valkyrie crosses a short distance while dropping bombs, Gatling Gun reduces armor and magic resistance, and Missile Barrage stores ammo of which every third shot is a big Bertha.

Harassment

When: An enemy is within range.

Phosphorus Bomb damages and reveals the area, Gatling Gun fires in a cone, reducing armor and magic resistance.

Repositioning

W › R › AA AA

When: You want to hit and move.

Valkyrie moves you a short distance while dropping bombs and a trail of fire, then Missile Barrage fires.

The siege ultimate

Laning phase

Your passive converts part of your attack damage into true damage. Gatling Gun reduces the armor and magic resistance of enemies hit.

Common mistakes

• Wasting your ultimate's missiles.
• Using Valkyrie without looking at its direction.
• Neglecting Gatling Gun: the resistance reduction is significant.

Riot's official tips for 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.
