When to pick Corki

As of patch 12.8, you can first pick Corki as he can be flexed mid and top. He is a counter pick to control mages, anti melee champions like Illaoi and Graves, and enchanters. Ask to swap lanes if you have a bad matchup. If you still have bad matchup because both mid and top picked a diving champion, then change your secondaries to Conditioning and Overgrowth for the Immortal Shieldbow build. He is the best poke mid in the game.
Back to Top

Summoner Spells

Flash is mandatory on this champion. Teleport is good since you are only picking this champion to counter pick.
Back to Top

Runes

Future's Market against free matchups or biscuits against tougher matchups. Futures with first strike would let you buy completed items earlier when dragon is coming up.
Back to Top

Items

Doran's Blade start is good against divers as they want to all in you. Corrupting Potion is better against range as they want to outsustain you.

You then get tear first back and rush Manamune.

Then usually a Sorcerer's Shoes since much of your dmg is magic, first used by the player Score from KT Bullets.

Next Ravenous Hydra for ability haste and omnivamp to heal you.

Third you get luden's since it's mythic passive of magic penetration is best for you.

After third item, it is situational. Demonic Embrace against enemies building health items. Void Staff if not and they're likely to build magic resist. Shadowflame if none of them will build magic resist.

A few of your enemies may be divers, so it would be ok to get defensive items after as your champion doesn't have good ap ratios for rabadon's.

Get Elixir of Sorcery for dragon soul and elder dragons; it is better than Elixir of Wrath since its passive is wasted as you do low physical dmg. When lvl 9 in game as mid, get Farsight Alteration to ward your jungle bushes to cover flanks.

lastshadow9 had said Corki should sell Sorcerer's Shoes end game for magic item.
Back to Top

Timers

You should always time the enemy summoners. Do this with ctrl a then ctrl c after typing the timers and later remind your team with ctrl v. You should always time the enemy summoners. Flash is 5 min, but Ionian Boots of Lucidity reduces flash by 30s, Cosmic Insight reduces flash by 46s, together reduces flash by 69s. Exhaust and Cleanse are 3 min 30s while Ignite and Ghost are 3 minutes. Teleport can be looked at by holding tab and divide their teleport cooldown by 60. Heal is 4 min. Buffs are 5 minutes if you dont have vision of their buffs to make use of riot's buff timers. Dragon and baron are timed by the game scoreboard. inhibitor is 4 min.
Back to Top

APM

Actions per minute; you should try to never stand still. It will warm up your hands if you keep clicking in left and right or in circles. Also do some wrist exercise so you don't develop anything bad.
Back to Top

Skill Usage

In lane you want to Phosphorus Bomb auto when you trade since the enemy can dodge your q easier if you use it after you auto. Also there is a delay since the skill shot is lobbed. It is a bit longer range for harass compared to auto. Don't activate Gatling Gun if you are just going to run away.

You can't Valkyrie through nexus when going mid lane, you can Valkyrie from fountain.

Note: no Trinity Force in my build currently. Use Missile Barrage to activate Trinity Force procs when killing structures, but in fights you generally use any one skill before each auto. Also in fights just use Gatling Gun right away since your Missile Barrage has good cd to activate Trinity Force procs.

The Package from Hextech Munitions does an insane amount of damage but you don't always get to use it. Usually used to knock aside enemies and make sure you can get out alive, if you can't get out alive then don't use it offensively. Remember you get an extra Valkyrie after using the Package. Generally use it to kite against divers when they get next to you.
Back to Top

Jungle Tracking

Wards won't be enough as good jungle players know how to get around them. You need to keep track of junglers by their pathing. First know which side they started by a deep ward or on his teammates leashing. Be careful though, as people can fake leash. Ping on the map which camps the enemy jungler should be at and all laners should play accordingly. If you ping jungler is on opposite side of map while your jungler is on your side, you should trade with the enemy laners. If jungler is on your side, then play safe and do not push lane.
Back to Top

Champion synergy

Blitzcrank needs kill pressure, which Corki can apply.

Thresh needs kill pressure, which Corki applies.

Poke comps with many ad sources of dmg can use Corki rather than Lucian or Caitlyn.

Team with heavy ad dmg benefits with Corki.

This champion is not good with double ap.

Leona needs kill pressure, which Corki applies.

Nami and her Tidecaller's Blessing on you with sorcerer's shoes can do a good amount of dmg.

Jayce physical poke dmg coupled with your magic poke dmg can siege very well. You should have an ap top or jungler. For example Maokai or Rammus.

Janna and her disengage kit lets your team poke more. Her ad bonus of Eye Of The Storm lets your skills hit harder.
Back to Top

The level one before minions spawn

Do not pick a skill yet until you see your lane opponents in lane, when top laner appears at top to show there is no lane swap, or there is no delay invade. Your first skill in all but one situation should be Phosphorus Bomb, but if you get caught then get Valkyrie. You should defend a choke point safely. If defending top river, do not stand in bush. If defending mid lane then have vision of both bushes and no need to have vision of their tower. You should use your trinket ward if you see a group of invaders then you ward where you are escaping to. If you ward in front of them they can kill it. A delay invade optimally happens at 1:25. If an enemy sees you when you are about to ward, its better to back off and ward a spot that they cannot see even though it is not as deep.

Against certain junglers that can invade after red buff, such as Graves may be good to ward dragon. If you can push safely, then ward raptors to track the jungler.
Back to Top

Leashing

If jungler starts at top and you're top, you leash until 1:36 which you then go top. If a cheese can happen top, just ward it beforehand or go the long way around. If you know who is going into your lane then use your skill to help leash. Use Phosphorus Bomb at 1:36.

As mid, you do not leash.
Back to Top

Minion advantage

Generally for all lanes, if you have more minions you can go aggressive if you know where everyone is in the map; but not past the minions if you need your minions to help fight the enemy champs, unless you can completely zone them. If there are 10 enemy minions and you have 3 minions just back up all the way to tower as you will get collapsed on by the enemy. Since you will not lose any cs(creep score), you might as well go back to tower anyways. It takes 7 minions as solo lane to get lvl 2 so you should count both minion waves to see if you get lvl 2 first, they get lvl 2 first, or both sides will get lvl 2 at the same time. If they are getting lvl 2 first then you're gonna have to back off far. If the lane is even then you have to be cautious. Only do short trades when playing aggressive or else you take too much minion damage. You can go for longer trades if you notice that you benefit more from it.
Back to Top

Recognizing tower dives

You should watch your lane and your teammates to see if they have the factors of getting dived. The most obvious one is low health. Others are no flash, huge incoming minion wave, and champions missing. If you pay attention to other lanes or yourself, you can warn the possible dive and move your jungler, others can roam to help, or get in a spot for a safe teleport, all to turn around the dive. If none of the responses are available then the possible victim must leave. The duo lane should generally be together when the minion wave is at their tower, or else the enemy duo can 2v1 dive the lonely bottom player. Tell that bottom player to leave or call others to turn the dive around.
Back to Top

Farming under tower

Towers will prioritize minions toward the bottom of the lane first. During early levels you can auto once on a full hp caster minion then tower shot then farm. The caster minions near the top of the lane will most likely get hit by your minions which means you need to auto those more than once or not at all. Use your skills to catch farm under tower as a last resort. Your support should help out.
Back to Top

Recall scenarios

Best case scenario is you know where everyone is on the map and you can safely push to their tower if you have more minions or freeze when they have a bit more minions. You can recall before a siege minion wave(which spawns after 2 minion waves during early game), so that by the time you go back to lane you won't miss out on too much cs since siege takes a while to be killed by tower as well as enemies can't push that fast.

If you killed your enemy laners and you do not know where everyone is on the map then you should go to your tower and recall. Do not risk getting killed by their jungler or whoever. If you got a successful jungler to gank you then ask him to push with you unless you are all low enough for a triple kill. After recalling, buy while walking to edge of fountain always until 20 minute mark.
Back to Top

Early game

Never trade if you are not full health.

You should conserve mana by not using Gatling Gun unless there is an all in or gank.

When trading, use Phosphorus Bomb followed by 1 auto then back up. You use Phosphorus Bomb first since if you auto first they can dodge Phosphorus Bomb easier. If you are not full hp and just want to harass then just Phosphorus Bomb since it is a bit longer range than 550 range auto.

Missile Barrage, like other skills and autos, should generally be used right when they go for a last hit. If you hit them then its good, if they dodge it when his cs is about to die then he will miss the cs. A win win situation. If they are about to harass you when you go for cs, then u need to pretend to go for a cs then back off to the left, right, or back to dodge the skillshot.

Ward mainly when you push to enemy tower or for lane bushes. You can fake ward by walking to a spot and pretending to ward.

Get all 3 skills lvl 3 if you expect gank or all in. Play back, preferably at tower, when support is missing.

Generally when your jungler comes, you let him show first before engaging since you don't want to die in a 2v2 before ur jungler gets to do anything.

At the 8 minute mark your passive spawns The Package. Generally save it 30 seconds before dragons. After you base and buy use Valkyrie or walk while buying to get to the Package and pick it up.
Back to Top

Mid game

Mid game generally starts when a tower dies or when someone gets lvl 6 as they can tower dive.

Just get experience and play safe to wait for next dragon fight. This is why late game counter picks are best. Be in side lane to get solo experience. If your tower is taken, freeze the lane until your laner enters a fight. You will get experience while they lose that side lane experience.

DO NOT DIE FOR A TOWER. Even if it is one hit away, just get it later when it is safe.

Only buy Control Ward for dragons.

Always group for dragons, you can use Teleport to come back to dragon when low or to catch experience in a side lane.
Back to Top

Late game

Never get aced as just a siege wave is enough to end the game.

It is ok to lose inhibitor . Just focus on dragons and protecting nexus towers. Always take dragon over baron unless it's cloud. Always take dragon over towers and inhibitors as well. Do not take base towers if dragon or baron is coming up soon as the enemy will generally respawn in time.

If you have open nexus(no nexus towers) then sit in base until all inhibits respawn.
Back to Top

Dragon

Only do dragon when 2 enemies are dead or at base & while your team isn't low, or it is a free dragon. A free dragon is when the enemy team is aced, their teleports are down, completely cleared their vision, they're taking top buff, or recalled to base.

If they have Fiddlesticks, Nunu & Willump, Master Yi, Udyr, Shaco, Elise, Karthus, Lee Sin, and possibly more(not to mention laners helping out), then you need to keep it warded from a specific lvl onward for a possible sneak.

If the enemy starts dragon, poke them until dragon is half hp, then fight. Poking them makes them disoriented to either finish, run, or fight. Dragon does aoe so if you start it, have one person in the pit to tank it away from team.

Always team fight for the third dragon as everyone would be closest in items. As scaling team, you can give the first two if not safe to contest.

Prioritize dragons over everything else.

If you have dragon soul, instead of starting elder dragon camp the enemy jungle and fight. If playing protection composition, backline hits dragon while frontline zones, then get off dragon if they go in.
Back to Top

Baron

When securing baron for bait or to take, you want to deep ward and ward surrounding bushes to keep from getting stolen or to get a pick. Do not exclude the tri bush towards top lane.

As red team you want to pink outside the pit and sweep inside the pit.

As blue team you want to pink in the pit near the entrance so that the enemy doesn't kill it over the wall.

Do not stand behind the baron when taking it, since it will do damage to everyone behind it.

As for positioning when taking baron you need to stand outside the pit with your carries. As for ward kills in the pit, support should be the one since support's dmg against baron is least important. When the enemy is in the baron pit, hit the baron to make it hit your enemies. Never use your cc at baron when enemies are around. One person should zone the enemy team if they are coming to stop the baron attempt. Communicate with your team beforehand to finish, run, or turn to fight.

At 20min and onwards you must ward it against sneaks from high objective junglers such as Nunu & Willump, Udyr, Karthus, Fiddlesticks, Master Yi, and possibly more(not to mention laners helping out).

Always take baron over inhibitors.
Back to Top

Team fighting

Preferably poke down the enemy before fighting. Tell your team to not engage so you can poke. You try to position yourself where you can deal 100% dmg w/o interruption. Which means going to 1v1 an enemy carry isn't always the best option. Prioritize the squishiest enemy or highest threat when they get in your range. This means you don't always hit the tanks first for some fights.

As a poke champion, you generally do not want to auto attack during team fights.

https://youtu.be/VwoHBLS5MXs?t=1961
Corki should have not gone after caitlyn and just use his aoe damage in that jungle fight on the other 4 members. He wouldn't have gotten hit by any cc.

Another example: if Leona and Lucian are in your range, then hit Lucian while avoiding Leona skill set as best you can. If you are in danger then generally you want to go to your teammates rather than away, unless you got Fizz ulted or something.

The Package from Hextech Munitions during a team fight depends on your situation. If all enemies used all of their cc then you can Valkyrie in, then Valkyrie out in a 5v5. Primarily use it to knock aside multiple people rather than hoping they will walk on the trail. In early game small skirmishes like 3v3 or 2v2, you may not need to Valkyrie out right away since enemies usually won't have the burst that early and are getting hit by your teammates. Generally use it defensively to kite divers.

Conclusion

Corki is strong first pick as flex in the draft is valuable. All questions in the comments will be replied by private message. I stream on twitch.tv/bive and offer coaching lessons for all roles for $20/hr. https://www.youtube.com/user/sinc67/videos is my youtube.
