Hey, this is #22. I recently play Zed as a mid laner, high burster assassin. I am still in silver, but I think playing with Zed is one of the most useful think in low elo. This guide is for Summoner's Rift. I hope it will help you to become a better Zed player.

Pros

+ Good mobility
+ Insane farming
+ Lifesteal and Armorpen.
+ Ultimate cooldown is so low

Cons

- Hard to master the combos
- Depends on the positioning
- Hard to choose the right item

For marks I take Greater Mark of Attack Damage for a faster clear time in the jungle and easier last hitting when covering lanes. An alternative to this is taking Greater Mark of Armor Penetration which will allow more damage in the mid to late game. A third option is Greater Mark of Attack Speed as this both increases your overall damage and lowers the cooldown of your q.

When it comes to seals I personally feel like Greater Seal of Armor will give you the best bang for your buck. However they are not your only option Greater Seal of Critical Chance is another good option on Zed due to his passive effectively making twice the number of seals. The problem with this second option is that it makes you far weaker in the early game.

I personally like Greater Glyph of Magic Resist as you quite often don't have to worry about the enemy magic dealers till the mid and late game. You can also grab Greater Glyph of Attack Speed for a little extra damage and cooldown reduction on your q.

With Zed you have a tremendous amount of versitility with your quints. I prefer to take Greater Quintessence of Armor Penetration however Greater Quintessence of Attack Speed and Greater Quintessence of Attack Damage are two popular and effective alternatives on Zed.
