Corki: So this is a Corki build. Its niece but it works. Your going Top. You need to exploit your range to constantly farm (and poke) from a safe distance. Use your W to get away from your enemies when your engaged on. In the early game, using it for anything else will get you killed. Lucky for you Corki is NEVER played so Corki is never banned. In this build your items are key and if you don’t have enough items you will be uslesss in the way your trying to play. You are a Diver. You are also (because of your item reliance) a late game champion. You will not be buying boots. Stats will be more important.

Skins: Fluffy Corgi is sooo CUTE!!!!!!

Summoner Spells: You won’t be taking boots so Ghost AND Flash is what you’ll need.

Items: This is the most important part of your build. One change to the item set and nothing will work. Arch Angels staff: Corki has mana. Try to get this item fast. After you have it you can spam your abilities and use the shield while engaging onto the the enemy team. The shield only comes in handy when you have at least gottan Spirit Visage. Note that you scale with both damage and AP. Rylai’s Crystal Septer: This turns all your AoE abilities into AoE slowss. Your E is risky to use before you have this but after its a lot safer to use. Also the extra AP and HP is pretty nice. Spirit Visage: the extra healing it will give you is great. It goes with: Trinity Force’s healing, Its own healing and life steal form your Runes. It also has sooo many other stats that really help your tankyness. By now you can all in. Just be careful. Trinity Force: Bolth passives on this help. You’ll be auto-attacking while using your abilities. You also don’t have boots so the other passive will make you more sticky in chases. Storm Razor: If your going to change any items, this would be the one. Still, the slow, extra damage and critic chance just, feel right and the stats work pretty well with your kit. Last you should buy,: Gaurdian Angel: after they do all their damage, and they finally kill you, SIKE!!!! When you’re full build you can do practically anything because your are sooo tanky.
Also Hex-tech belt is obvi.

Abilities: Obviously upgrade your ultimate whenever you can. Not much else. Your ultimate is a game changer because it allows you too chunk people. Your W is an disengage until your tanky enough to survive burst. Your Q is poke and vision. In the late game the vision matters less because even if your getting dived on you won’t die anyway. (The late game version is THAT tanky)

Runes:
You have two rune paths.
1: Poke & Kill. You will take some hits in the early game but Fleeted Footwork will help you regain that lost health. Overheal and Legend Bloodline have good synergy. Coup De Grace will help you finish off your low health squishy targets. Overgrowth and Conditioning are max HP sooooo, you know.
2: SCALE!!!! If you use grasp you will to have to take more hits but it will make you scale better. Demolish will help with your push power.

Threats: Any one who can dive and kill you in the early game is a HUGE threat and can ruin everything. Lux is nice to have on your team. Squishes are easy to kill because you’re fast and tanky and have a bunch of easy to hit moves. Summery:
Bad against: Early game, hard engage, fast cc
Good against: pretty good burst, can killl mobiles, dashes, (Ahri)
as of 11.00 this build is no longer relavent. I will post a new build once I find out what works for corki in 11.00. as of now using seperaphs embrace wont fix your manan problems like it used to.
