You need the teleport spell at Zed therefore you'll be able to teleport at the bot lane, get kills and then return back to your lane so you wont.And the Flash spell so you can do good escapes when the enemies attempt to gank you or to cast your ultimate spell and get a kill
.

Zed needs to farm minions alot. With his spells you can farm easily but you must have the proper knowledge for using his energy properly

A quick and amateur build around zed.

Zed can be good at ranked games due to his high damage and his ability to escape. That makes him kill enemy champions and escape as well
