I take mekipendant and do it to manamune quick cus when u wanna farm its good with mana and mana regen like u can use q much and get mana fast after. If u are solo i dont recommend this build cus this build is more if u have like a partner that can help u out if u got trubel. Ok now to skills i take Q in lvl one and max it first to see ppl early in shrubs and W in lvl to to escape when low on hp. And E are i taking lvl 3 cus i dont like it so much. And ultimate i just wait to get 7 and then use if on farming sometimes but the super rocet du u need to do some dmg. I take my runes to get more mana regen, AD, and less cooldowns, and HP. I play aggressive in game but if in with a ranged and against 2 melee i play a little bit less aggressive cus i dont wanna die taht fast if its AD and AS melees.

farming is a very good thing with corki the hes combo Q and E is very good in farming. His ulti is nice at farming jungle sometimes but u have to make sure u dont use all ur ammo cus u need it in fight and team fights.

This are not all the acronyms I used, just some important ones that are needed for understanding what the hell im talking about

AD-- Attack dmaage
AP-- Ability power
Arp-- armor penetration
BC-- The black cleaver
CC-- Crowed control
DPS- Damage per second
CD-- Cool down.
LW-- Last whisper
UR-- your
U-- you

I want to say a few words about last hitting.

Last hitting with Corki is extremely easy. He has an excellent attack animation, and with these runes and masteries, including the passive, at lvl 1 you will hit minions for~80 damage. In addition, you can use Phosphorus Bomb to kill multiple creeps.
The only problem you will face is if you are pushed to your turret.
If you don’t know how to last hit under tower, this is how it's done:

Melee minions- Let the turret hit it twice, than hit it.
Mage minions- Hit it once, then let the tower hit it, then hit it again.

In addition, Use Phosphorus Bomb if your autoattck will not be able to finish the creep before the tower hits it.

More tips:
If you aren't good at last hitting, play a custom game and just practice it.
Basically, the idea is that you want to wait and hit a creep only when it's HP is low enough so you can finish him in 1 hit, and not hitting it before (when you attack creeps for no reason, you push the lane).
There are 2 ways you can do this:
- Press on random spots near your champ to make him move a bit so he won't hit the
creeps, then Hit the itp when he is low enough.
- get near the creeps and hit S. Your champ will not take any action. Then hit the creep when he is low enough.

Another trick, is Using A to last hit. When pressing A you will be able to aim your attack as if it was a targeting-skill. I find it very helpful. You are less likely to hit the wrong creep.

team work is nice i think and if ur team dont kill one u can go behind the wall and use ulti to get a kill for UR team. And if U are late fir a fight U can use W to get a good run. i rly love it cus i get many kills and less death so its cool and if ur all team is dieing and and died u can escape with W.

Thx for voting and comment plz i rly want to hear what u think and thats good is u comment thx.
