I would like to introduce myself my name is Root289. I am a teenage Russian guy, playing on servers around the world.
So this is my first guide ever. I would love feedback! This, I made for my friend who recently started playing LoL. I would try and include as much info as possible, but at the same time keeping it short. I will update it frequently. So shoutout to my friend GERARDOCH2298. So lets dive in!

I picked flat AD runes as main, as it can really help you fight your way through early game and have a little bonus by the end of the game. You could also run AS marks with AD quints.

At lvl 6 try to look an open gank midlane, if there is no possibility then just keep farming. In teamfights you are the initiator - you have to jump in and ult. The armor penetration will do its job while the rest of your team joins in. You should find a squishy that you can kill easily. If you can't find any, then you definitely have to peel (protect) for your squishies.

You have a lot of potential in escaping/closing in in a fight/gank. You can use your 'w' to escape or "secretly" close in on your opponent then you can quickly 'e,q' on to him and ult. This combo works very well especially if you have some other form of CC in your team!
