To start off with him you will need to go to the red camp solo and tell your teammates that you will be fine. After that you will need to auto attack it first and as soon as the monster attacks you use your q making him stop his animation after that just keep on auto attacking until your q is ready to use again. After that move to the birds and auto attack the big one twice before using your q and then to a smite after that use your e to clear up the little ones and drink one of your potions. After this if your lucky enough go to the scuttle and kill it however if someone already is attacking it use your last potion and wait till the scuttle is low hp to swipe in with a q to steal it and then use your e to attack the damaged champion. After that go into the enemies blue camp and see if there are any leftovers you can take. After that you recall back and buy your stuff.

At lvl 5 you should be able to slay the drake by attacking it first with an auto and then when it airborne s you, you use your q to go back into close range and then e and repeat q and e to kill it after you killed it you should see if there is a scuttle to kill and then go check the enemies blue camp.

When your fighting someone you want to start off with a q then your e if you seem like you're losing the battle use your w and whilst amidst your healing use your challenging smite to deal some damage and then by the time your w has ended use your q again and e.If you are chasing a champion with low hp use your challenging smite to slow him down or even finish him if he's that low.

To be honest most of the times you will be only just using q and e

First scout out the weakest champion then go in with your r and use your q to hop onto that opponent and kill it then use your q again to hop onto another opponent and use e to kill that one and then use your q to hop on another one.

The thing about yi is that he can quickly kill his opponents and even 1v2 or 1v3. Also that yi doesn't require too much skill to play which makes him an easy op champion. He can use his q to dodge,kill or escape he is also quite a good jungler due to him actually being able to solo red and blue camps at level 1.

However there are some cons with Yi as is with every champion and that is that Yi is in my opinion not very good against tanks due to that his damage is good but it will take a lot of hit to take them down and by the time you have your already dead "Omae wa Shinderu".

Hopefully you enjoyed this guide to Master Yi and I would enjoy it if you guys could give me feedback in what I could have done better or suggest me some champions are having some problems with and I could edit this guide to tell you how to go against that champion.
