Threats to Corki with this build
|Ashe||She has an annoying laning phase with her W poke but if you don't lose too hard late game should be in your favor. She's immobile so your burst combo should land, unless she flashes. Also you can build mercurial scimitar for her ult.|
Introduction to build and Corki.
This is a comprehensive guide for ADC Corki. This guide will include: Runes, Masteries and Explanation, Summoner spells and Explanation, Ability upgrade path, Item purchase path, Explanation of his Abilities, Counters to Corki, Pro's/Con's, When to Pick Corki, and when to use Hextech Munitions. If this guide helped you win a match or you have any criticisms please do tell me!
Corki is a magic damage based ADC but don't let that change your build, you still need to build somewhat like a normal ADC. Corki has great siege with his Phosphorus Bomb and Missile Barrage combo that clears waves and Missile Barrage that has a low cool-down that pokes down enemy teams. This Phosphorus Bomb and Missile Barrage combo also gives Corki great burst. Corki is great to pick as an ADC when your team is super AD heavy, for example when you have a Zed Mid, a Kayn JG and a Renekton Top, I'm totally not talking from experience.
Why should you trust a schmuck like me?
My name is Hingushu and I'm a Gold 3 ADC main. I've played since 2011, I've mained every role at some point but the role that got me to G4 is ADC and my first main as an ADC was Corki. Though I don't play him too often anymore, I only play Corki when my team is AD heavy.
Let's begin with his passive! Hextech Munitions makes Corki's auto's deal bonus damage AND half of it's damage is converted into magic damage. This is why Corki still builds AD items instead of AP. It also spawns a package at your spawn that when you right click it, it gives you movement and enhances your W , making it go farther and deal more damage.
Next is his Q, Phosphorus Bomb. Corki, upon using his Q lobs out a bomb that deals AOE damage and reveals units. This ability is great for wave clear since it's AOE, it's also good for gaining vision on bushes. It's also an important part of Corki's burst combo.
Thirdly is his W, Valkyrie. This is Corki's only mobility, it has a high cool-down and high mana cost but it does go fairly far. When enhanced by the package it can be used as a great initiator. Also as a great escape tool. Use wisely based on your team, your build, your enemies and their builds.
Fourthly is his E, Gatling Gun. This ability shoots bullets in a cone in front of Corki. It also shreds enemies armor and magic resist, though it is a flat number that goes up per level (4/8/12/16/20).
Lastly is his R, Missile Barrage. This is a spam-able ult, it has low mana and CD. Also the missiles stack over time. Every third missile is a "big one" meaning it will deal extra damage.
Summoner Spell Explanation.
When to Play ADC Corki.
Since you still deal most of your damage via auto's you will want to take Fury instead of Sorcery.
Depending on your lane match up you may want to take either Feast or Fresh Blood , Feast for better sustain and Fresh Blood for better trading.
The same goes for Vampirism and Natural Talent , Vampirism gives you better sustain and Natural Talent gives you more damage.
As ADC Corki I only recommend Bounty Hunter .
As ADC Corki I only recommend Piercing Thoughts because your auto's convert to AP Damage.
I recommend Warlord's Bloodlust over Fervor of Battle because without it Corki's early game is weaker and this is where he shines.
Cunning VS. Resolve
I take 12 points into Cunning when I feel like I'm in a safe lane, if I feel like I'm at a great disadvantage I will put 12 points into Resolve for sustain.
The 12 points I would put into Cunning are: Savagery , Secret Stash , Merciless and Dangerous Game
I take Savagery because it helps you farm better and also Wanderer is useless for ADC's because you really don't roam that much.
I take Secret Stash because ADC Corki doesn't benefit from the increased buff timers from Runic Affinity , he should also rarely be alone for the benefits of Assassin
I take Dangerous Game on ADC Corki because Bandit and Greenfather's Gift are both inefficient.
The 12 points I would put into Resolve are: Recovery , Tough Skin , Runic Armor or Veteran's Scars and Insight or Fearless
I take Recovery because you benefit more from the HP regen than you do from the gained resistances of Unyielding
I take Tough Skin because in bot lane trades auto attack's are a majority of the damage. Also Explorer is only good for roaming which ADC Corki shouldn't really be doing, and Siegemaster only helps you when you're pushed into turret, but Corki has good wave clear.
Ability Upgrade Explanation.
You should get Phosphorus Bomb first level one because it's the best ability for early trades. You should most likely get Valkyrie level two because it's your escape/gap closer. Then you should level up Gatling Gun level three so you can reduce Armor and MR. From there on out you should max Phosphorus Bomb for damage, then Gatling Gun for the same reason. Then of course your Missile Barrage and Valkyrie.
Your passive, also known as Special Delivery will be spawned near the fountain. Once you pick it up you gain movement speed and your Valkyrie is enhanced, you go farther and the trail you leave burns like napalm in Vietnam. After using your enhanced Valkyrie you will be able to use Valkyrie again immediately. The best time to use this is when engaging, but you're an ADC and should be very careful with it. Don't engage teams with it unless your team is with you. It's great for catching out a single champion. If you place the trail ahead of them,they can't retreat and they will either be forced to fight you or run through your passive. If your team has low engage a good item to get is Guardian Angel so you can go balls deep with your package and still live to tell the tale.
