I'd like to just say thank you for reading the guide. I am a gold Zed main and even though I'm not challenger or anything along them lines, I can still teach you the simple Zed facts you need to know before taking him into game. I'd just like to warn you, this guide will not help if you are not mechanically skilled to a certain extant, I wouldn't advise playing Zed if you're not super skilled at the game, but here we go.
This section is pretty simple, as Zed needs to snowball in lane. Taking ignite is super important, none of the other summoner spells don't really apply to zed, however if in a super difficult lane, you can choose exhaust or cleanse.
