Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
In the short time that Zed as been released, I have discovered a very powerful and unique potential that this champion has. Not only can he burst down a squishy caster, or carry. He can also deal a lot of damage to tanks or off tanks as well. The key is to know when to attack, and how to build him.
Pros / Cons
He is not very strong early game. You have to know how to poke safely and when to go in for a kill.
