Not Updated For Current Season
Hey, this is a build that alot of people may disagree with. I've played this build for months and I love it, I always have positive stats (If I'm not very unlucky with the team). This guide also goes for mid early game.
First you would start off by just harassing your opponent with "w", just make sure you hit him, as this is not very mana efficient.
I usually go for my first shopping trip when I have enough gold for Tear of the Godess and Tier1 boots.
In fights you would be the carry. You will always have to stand behind your team, spamming "W" and "E", when your enemy team is bunched up in a line, you could easily strike them all out with combining "W" and "R"
