Hello and thank YOU for clicking on this guide. My name is RAPMONSTA2 and I create champion guides & stream on Twitch. I love League of Legends & also love to share my knowledge in the ever-changing world on the Summoner's Rift. I've been playing League of Legends since season 3. I am a Mid-lane main and my favorite champions include: Ryze, Corki, Cassiopeia, Anivia, Twisted Fate, Orianna, and Fizz. I had a TON of fun making this guide for YOU. Any and all feedback would be greatly appreciated. If you have any questions, feel free to tune into my Twitch stream and ask in the chat.|
Without further ado, let us get into the guide.
+ Insane DPS
+ Free Rumble ult every 8 mins from Hextech Munitions's Package
+ Shreds Armor & MR with Gatling Gun
+ Great poke from Missile Barrage
+ Great DPS choice if your team comp is all-AD
Corki is a great pick in solo queue. He has an overall safe early-game/laning phase. Corki scales really well into the mid-game. Once he get his Crit items, Corki has potential to 2-shot squishies. Overall, Corki is a great option for Mid if you feel like your team lacks damage or has too many AD-champions.
- No CC in his kit, just pure DPS
- Susceptible to CC
- Does not do too well against assassins
- High item-costs; requires a TON of gold
- Does not fare too well against tank-heavy teams
As per all champions, Corki has his strengths, and his weaknesses. He does not offer any CC so it is harder to set up ganks compared to other mid-laners with CC. While Corki pumps out insane damage with his Crit items, it requires a TON of gold to get to that point. By roaming efficiently with Hextech Munitions's Package, Corki can pick up kills and objectives to snowball towards his Crit items.
|Flash is a must-have in order to make plays and get out of sticky situations.|
|Ignite will give you kill pressure in-lane & counters healers, such as Vladimir and Swain.|
|Teleport gets you back to lane quicker and Teleport to other lanes and help turn ganks.|
|Cleanse is a MUST when you are vs. Twisted Fate & other heavy-CC champions.|
|Exhaust will help negate all-in potential from assassins, such as Zed, Fizz & etc.|
|Heal is a better option than Barrier if you plan on roaming together with your jungler. ]|
|Barrier is a better option than Heal in 1v1 situations.|
|Ghost is great if you need to kite and/or gap-close.|
|Fleet Footwork: Fleet Footwork gives Corki sustain in-lane so he can safely farm towards his items. Fleet Footwork along with Doran's Shield start aids Corki through lane.|
|Triumph: The 12% missing health restore after takedowns from Triumph & the HP-sustain from Fleet Footwork & Doran's Shield keep Corki alive in teamfights, even when he gets low.|
|Legend: Alacrity: The extra attack-speed is nice and helps with CSing in-lane.|
|Coup de Grace: Coup de Grace helps Corki finish low-health targets and synergies well with Missile Barrage. An alternate rune would be Cut Down if the enemy team has multiple tanks, as Cut Down will help you DPS the tanks.|
|Celerity: The movement speed from Celerity and the adaptive-AD from Celerity synergies well with the movement speed from Hextech Munitions' Package and Trinity Force’s movement speed passive.|
|Gathering Storm: Gathering Storm gives Corki even more AD/damage the later the game goes, which doesn’t hurt to have more of.|
|Hextech Munitions (Passive): 80% of Corki’s basic attacks are converted into Magic Damage. In addition, every 8 mintues, Corki get The Package.|
|Phosphorus Bomb (Q): A flash bomb that does magic damage to an area and also reveals units in that area. It is Corki’s main wave-clear and AOE damage source.|
|Valkyrie (W): It’s Corki’s main gap-closer and if he has The Package equipped, he gets an extended Valkyrie that burns enemies over the trail of fire left behind the Valkyrie.|
|Gatling Gun (E): This shreds the enemies’ armor and MR while also doing damage. It is great against tanks early on and also helps wave-clear.|
|Missile Barrage (R): Corki’s main poke source and also a great way to proc Tri-Force passive by weaving in Missile Barrage between auto attacks.|
|We want to max out Phosphorus Bomb first because it is Corki’s main source of wave-clear. Then max Gatling Gun second as it shreds Armor and MR so Corki hits even harder. We level up Valkyrie last. Rank up Missile Barrage whenever possible.|
|When should I go Sorcerer's Shoes? If the enemy team has not yet built MR yet and for the extra magic penetration.|
|When should I go Ninja Tabi? If the enemy team has multiple AD champions and/or if you are against an AD-assassin, such as Zed, Talon, Jayce, Pantheon & etc.|
|When should I go Mercury's Treads? If the enemy team has multiple AP champions and/or if you are against an AP-assassin, such as LeBlanc, Katarina, Fizz & etc.|
|When should I go Boots of Swiftness? It is rare to go Boots of Swiftness but only if you REALLY NEED the movement speed.|
|When should I go Mobility Boots? If you plan to roaming a ton.|
|When should I go Ionian Boots of Lucidity? For the additional 10% CDR and the 10% CDR on your Summoner Spells.|
|Doran's Shield start on Corki is a safe starting item and works well with Fleet Footwork.|
|Trinity Force gives Corki all the stats he needs and Corki can proc the Trinity Force easily with Missile Barrage.|
|Infinity Edge is our main damage item, as Corki builds Critical Chance.|
|Statikk Shiv helps Corki stack Crit chance and waveclear with Statikk Shiv’s passive.|
|Rapid Firecannon extends Corki’s auto range and synergies well with Statikk Shiv.|
|When should I go Mercurial Scimitar? If the enemy team has CC and you did not take Cleanse.|
|When should I go Maw of Malmortius? If the enemy team has AP-assassin champions, and/or it is difficult to deal with poke from AP champions.|
|When should I go Void Staff? If the enemy team has multiple MR items, then Void Staff is a great choice because Corki’s passive converts 80% of his auto attacks into magic damage.|
|When should I go Guardian Angel? If the enemy team has burst, such as Zed, Fizz & other assassins.|
|When should I go Hextech Gunblade? If you feel like Corki needs more damage, Hextech Gunblade gives both damage and sustain.|
Corki is a very safe laner and has a really strong mid-game. In this guide, we will talk about how we can get to his strong mid-game and let YOU take over the game as Corki and climb the ranked ladder.
Pre-6: Generally in-lane as Corki pre-6, you want to be wary of ganks and not push too hard/fast,as this will open you up to being vulnerable to ganks. Keep the wave even in the middle and poke as much as possible with your auto-attacks. This is extremely important against melee-champion. Because if you allow melee-champions to just free-farm, while you keep the wave even, they will hit their power-spike and just kill you in-lane. So, it is REALLY important to auto-attack the enemy champion as much as possible & bully them out of lane early. An ideal situation would be to zone them off the wave, while having it frozen just in-front of your tower. Pre-6, we are just looking to back at around 1100 gold - 1300 gold. The ideal back timing would be between level 5-6, and enough gold to buy a Sheen.
Playing around your Package: You want to keep an eye on your Passive timer and back accordingly. Package gives a TON of movement speed to get back to lane or roam to other lanes for ganks/lane ganks. If you plan to backing for your Package, hard-shove the wave before backing so your laner is occupied farming under tower while you look to roam with Package.
Power Spike: Corki’s has multiple power spikes. One is when Trinity Force is completed. Another power spike is when Infinity Edge, Statikk Shiv & Rapid Firecannon are completed as you sit on 70% Crit chance.
If you are having trouble in-lane: If you are having a hard time in-lane, it is smart to delay your build and adjust your build accordingly. An example would be: Corki vs Ziggs, and I seem to have a hard time dodging Ziggs bombs, then I would go first item Hexdrinker for the MR.
Each lane match-up/game requires different ways to play the laning phase. Down below, I will try to give you as much information about the laning phase so you can apply this to imrpove your gameplay. During the load-in screen, you want to be actively thinking how you want to play out the laning phase and come up with a strategy on how to come out with a lead during the laning phase. By planning ahead, you are able to follow guidelines and set yourself up for success because you are actively thinking about what to do next/how to react to certain scenarios.
Laning Phase is one of the most important parts in League of Legends. It is the start of the game and a strong laning phase helps you smoothly transition into the mid/late game.
The Laning Phase composes of CS (creep score), Wave Control, Trading, and Pressure. Most players know only one, two or maybe even three out of the four major components of the Laning Phase. High-elo players understand how to efficiently control all four major components of the Laning Phase and therefore, are able to play their champions optimally. In this guide, I will break down all four major components of the Laning Phase and hopefully, help you gain LP.
The first phase of Laning is creep score or commonly known as CS. CS is the number of minions that you have collected gold from through last-hitting them. CS will be your MAIN source of gold income and helps you build items.
A perfect CS score at the 10 minute mark will be around 107-114. The important part of CSing is that you are consistent game-to-game and that you are building a solid foundation through your mechanics. If you are currently getting around 50 CS at the 10 minute mark, aim to improve and get 70+ next game. You can achieve this through optimal back timings, wave control, trading, pressure, and mechanics, all which we will talk about later in this guide.
The second phase is Wave Control. Wave Control or Wave Manipulation can be broken down into 2 basic concepts. The wave is either Pushing or Freezing.
Let’s talk about Pushing first because the majority of players will subconsciously just Push the wave without knowing the advantages/disadvantages of Pushing the wave. Pushing the wave is damaging the enemy minions faster than the enemy can, which creates an imbalance of minions for each side. If you have more minions than the enemy, you will create a Push.
Let’s break down the two different types of Push(s): Slow Push vs Fast Push
A Slow Push, simply put is killing the enemy caster minions first. By doing so, you are taking away the damage portion of the enemy minion wave. Remember, caster minions do the damage, melee minions do the tanking, and cannon minions do both. If you kill the caster minions first, you are taking away the damage portion from the minion wave and creating a slow push as the melee minions tank the minion damage. Slow Push(s) usually results in your minion wave stacking and becoming bigger (in numbers) than the enemy minion wave. Slow Push(s) are great if you are trying to roam, base, put down a ward, and/or tower dive. When you create a Slow Push into the enemy, the wave will eventually bounce back and cause a Slow Push back to you. Because of this, you will not lose out of much XP and CS from roaming or basing rather than if you didn’t Slow Push into the enemy tower and based/roamed.
Fash Push is where you are killing the enemy melee minions first. By doing so, you are taking away the tank portion of the enemy minion wave and creating a Fash Push because there are less minions to tank your minions' damage. Also, a Fash Push can be created by just killing as many enemy minions as fast as possible. Fast Push(s) are great if the enemy laner just based and you want to deny them CS and XP. It is also great if the enemy is low and you want to tower dive with your jungler. If you are Split-Pushing, Fast Pushing creates Pressure onto an objective. Also, you can Fash Push to set up vision around your lane if you feel like you may be ganked soon. Remember, Fash Pushing leaves you vulnerable to enemy ganks and it is highly NOT recommended if you are low-HP and/or do NOT have vision on the enemy jungler/laners.
The important theme in Wave Control is you want to be conscious on what you want to achieve with the minion wave. Are you close to leveling up? You might want to push to get level 2 before the enemy so you can get a more favorable trade. Are you against an assassin who excels in gap-closer? Then you might not want to push and give him a long-lane to gap-close onto you. Are you planning to dive with your teammates? Then you might want to create a Slow Push in advance, so you have a huge minion wave to help with the tower dive. OR you can Fast Push if you are short on time.
Pushing the wave will help you gain EXP faster due to the enemy’s minions dying faster. It also creates Pressure in-lane because you can push in the wave and threaten to roam to other lanes or invade the enemy jungle. Lastly, it forces the enemy laner to CS under-tower and have their tower take damage from the minions.
Freezing the minion wave. This is a harder concept for many players to apply to their gameplay. It requires patience and game knowledge. A Freeze is keeping the minions for both sides equal. To create a freeze, you would want to try to keep the number of minions for both lanes equal while last-hitting for CS at the very last possible second. The most optimal position for a Freeze would be right in-front of your tower but just outside your tower’s range. It creates Pressure on the enemy because they have to expose themselves to a gank by being so far up in-lane. Also, they cannot freely trade against you because they are threatened by the Tower. Also, CSing that far up in-lane will also open them up to being ganked. Just from this, a Freeze is great to set-up ganks and/or deny the enemy laner from CSing/trading with you. Also, Freezing the wave is great to limit the gank potential from the enemy jungler, if you are looking to deny XP and/or CS from your enemy laner, and if you want to base. Earlier we talked about Fash Pushing if you are looking to base. An alternative to having an optimal base timing, is to base on a frozen wave that is slightly pushing towards you. Not only do you get an optimal base timing but also get to deny CS/XP.
Let’s say you got a Freeze against you, how do you break a freeze? You can either try to wave-clear and reset the wave OR you can call for your jungler to help push out the wave 2v1 and reset the wave that way. The important part of breaking a freeze and resetting the wave is understanding what caused the Freeze in the first place and not repeating it again.
The third phase is Trading. Trading is dealing damage between laners. By doing so, you create Pressure by bringing down their HP. Now, you want to do more damage than your opponent in trades. But sometimes, you can get Trades where you take no damage while damaging the enemy laner. How? When the enemy goes to last hit a CS, they are in a vulnerable spot to take a bad trade. At that split-second they must make a decision. Do I go for that CS and take this unfavorable trade or do I forfeit that CS and not take this bad trade? This is what is called Pressure. They are pressured into making an uncomfortable decision in the heat of the moment. Abuse this to get favorable Trades in-lane. 99% of players do not actively look to trade when the opponent is about to go for a last hit on the CS. Trust me, this single concept alone can make your laning phase go from good to great!
The last and final major phase is called Pressure. Pressure is extremely important because it can translate into Tempo. Pressure is created when you push in the wave and look to roam. Now the enemy laner feels pressured because they have to decide, do I CS these minions and be late to the roam or do I leave the CS and match the roam? The opportunity cost created from Pressure can expose players’ flaws and poor understanding of the Macro-game. ABUSE Fog of War to create Pressure. Just the threat alone on being off the map creates Pressure on other lanes and put them in an uncomfortable spot.
All four phases of the Laning Phase are connected to each other and by actively thinking about what you want to achieve in the lane and executing that plan will build a solid foundation so you can smoothly transition into the mid/late game with a lead/advantage.
Other Key Concepts:
Positioning: Ask yourself, should I be sitting in my minion wave or should I standing aside my minion wave? If I am pushed up this far, how exposed am I to being ganked? Based on your answers, you should adjust your positioning to cover your weaknesses.
Build small advantages over the laning phase and they will add up later in the game. If you get a lead, snowball that lead to your advantage by either roaming to other lanes or killing your laner.
Now I will give you a common & difficult matchup to help you understand how to plan out the laning phase, and execute that plan.
Matchup: You are “Twisted Fate” vs an enemy “Fizz”
From prior games and game knowledge: you know that pre-6, Twisted Fate can poke and harass Fizz in-lane. But if you don’t poke/harass Fizz and create pressure in-lane pre-6, Fizz will kill you as soon as he turns level 6 with his ultimate.
How I want to play this matchup pre-6: I want to allow him to push in the wave as soon as the game starts but I want to freeze the wave just outside my tower’s range. Then, I want to create Pressure, where he is forced to overextend in-lane and CS is an uncomfortable spot. This exposes him to an early gank, where he can be set behind. Also, I want to trade every time he goes for a CS but I also want to be aware not to aggro the minions too long because it will break my freeze.
How I want to play this matchup post-6: Now that Fizz is level 6 and has ultimate, if I push the wave and stay in-lane, I will be exposed to being caught by his ultimate. So how do I counter this? I fast-push and look to create pressure by roaming. This covers my worries about being caught by his ultimate if I were to sit mid after I push the wave, and at the same time, I create pressure of the map.
