Corki ARAM Build and Guide

Updated for patch 26.21. Ability details come from Riot’s official game data for this patch; ARAM balance numbers come from the League of Legends Wiki’s champion data.

A Corki ARAM build is a Spellblade poke path: Trinity Force and Essence Reaver so every Missile Barrage sets up a stronger attack, then crit. The Howling Abyss is kind to him. 90% damage taken, 20 bonus Ability Haste.

A 2 second ultimate cooldown changes what a marksman wants from items, and his patch 26.21 kit drove every choice. Win rates weren’t used.

How is Corki changed in ARAM?

Two buffs. Corki takes 90% damage, which is a real survivability bump for a ranged carry with one escape, and he gets a flat 20 Ability Haste on top of whatever his items provide. Damage dealt isn’t on the list, so his output is unchanged. Where does the haste go? Mostly into Valkyrie and Phosphorus Bomb (Missile Barrage already runs on a 2 second cooldown with stored missiles, so haste matters less there).

Why does Corki fit the Howling Abyss?

He’s a long-range poke champion, and ARAM fights are mostly poke until somebody commits. Riot’s patch 26.21 data:

• Hextech Munitions (passive): part of his basic attack damage is dealt as bonus true damage.
• Phosphorus Bomb (Q): magic damage in an area, plus vision of units there for a while. Cooldown 9/8.5/8/7.5/7.
• Valkyrie (W): a short flight that drops bombs, leaving a fire trail that damages opponents who stay in it. Cooldown 20/18/16/14/12.
• Gatling Gun (E): rapid fire in a cone that damages and lowers enemy Armor and Magic Resist. Cooldown 12.
• Missile Barrage (R): a missile that explodes on impact for area damage; missiles are stored over time, and every third is a Big One. Cooldown 2.

Missile Barrage is the reason he works here. It’s an area explosion every 2 seconds, as long as he has missiles stored, and the enemy team stands in a narrow lane where area damage hits more than one champion. Phosphorus Bomb is area damage too. Gatling Gun lowers both resistances in a cone, which helps the rest of his team as much as it helps him. The catch is how much of his kit rewards standing at range and how little of it helps when a diver lands on him. Valkyrie is the only answer, and the 90% damage taken softens the rest.

What should a Corki ARAM build focus on?

Spellblade first, because he casts something every few seconds, then crit for his attacks. Four items plus boots.

Trinity Force is the core. Spellblade adds bonus physical damage to the attack after any ability, and with Missile Barrage firing on a 2 second cooldown, there’s almost always a Spellblade ready. Quicken, the other passive, hands him Move Speed on every attack (useful for stepping back after a missile). The Health in its stat line (333) is welcome on a champion who will get dived.

Essence Reaver second, a crit item with Ability Haste built in (20 of it, next to 50 Attack Damage and 25% crit). Its own Spellblade adds bonus physical damage and restores Mana on hit, and that Mana keeps missiles and bombs flowing in a long fight. The Ability Haste stacks with his free 20.

Next, Infinity Edge, which pushes his crits harder with 30% Critical Strike Damage on top of 75 Attack Damage and 25% Critical Strike Chance. Corki’s attacks deal part of their damage as true damage through Hextech Munitions, so heavier attacks mean more of it.

The last slot is Armor Penetration. Lord Dominik’s Regards adds 35% of it plus Giant Slayer against Health-stacked tanks, while Serylda’s Grudge gives 35% Armor Penetration with 15 Ability Haste and a slow on abilities against low targets. Boots: Ionian Boots of Lucidity for even more haste, or Berserker’s Greaves for Attack Speed.

How do you play Corki on the Howling Abyss?

• Keep a missile in reserve. They’re stored over time, and holding one lets you finish a low target the moment they step forward.
• Count to the Big One. Every third Missile Barrage deals extra damage, so aim that one at the biggest group.
• Save Valkyrie for escaping. It’s his only movement, and the free Ability Haste still leaves it a long wait at rank 1.
• Gatling Gun the frontline. It lowers Armor and Magic Resist in a cone, which helps your whole team’s damage.
• Use Phosphorus Bomb for vision. It reveals units in the area, which matters in the brush along the lane.

How do shopping and Mark work for Corki?

Nobody recalls in this mode, which makes the fountain your only shop, at the start and after each death. Sheen goes first, since Spellblade starts working before Trinity Force is finished. The Health relics along the lane are his only sustain, and he’ll want them between poke rounds.

Pick summoners carefully, because they don’t change mid-game. Landing Mark, the snowball, earns a dash onto the champion it struck. Should a poke carry take an engage spell? Usually not. Real talk, Flash and a defensive spell keep Corki alive longer, and alive Corki does more damage than a dead one who snowballed into five people.

Is Corki good in ARAM?

Yes. His two modifiers, 90% damage taken and 20 bonus Ability Haste, both help, and Missile Barrage is an area spell on a 2 second cooldown in a lane that keeps enemies grouped. To be fair, divers are still a problem, since Valkyrie is his only way out. Long story short, poke from the back and keep the flight for emergencies.

Who gives him a hard time in mid? The Corki counters guide has five answers. The guide to LoL roles covers what mid laners do on the Rift, and the LoL items database has current stats for everything above. You’ll find his planes on the Corki skins page.

In practice, the Corki ARAM build is Trinity Force, Essence Reaver, Infinity Edge and Lord Dominik’s Regards or Serylda’s Grudge, and the plan is a missile at the pack every time one is ready.

FAQ

Is Corki buffed in ARAM?

Yes. The Wiki’s patch 26.21 data gives him 90% damage taken and 20 bonus Ability Haste in ARAM.

What items does the Corki ARAM build use?

Trinity Force, Essence Reaver, Infinity Edge, and Lord Dominik’s Regards or Serylda’s Grudge, with Ionian Boots of Lucidity or Berserker’s Greaves.

Why build Spellblade items on Corki?

Spellblade empowers the attack after any ability. Missile Barrage has a 2 second cooldown, so Corki triggers Spellblade far more often than most champions.

How many missiles can Corki store?

Riot’s description says he stores missiles over time up to a maximum, without giving the number, and every third missile fired is a Big One that deals extra damage.

Were win rates used for this build?

No. The build comes from what Missile Barrage and his other abilities do in patch 26.21, matched with each item’s stats and passives.
