Hey, I'm MorroX, a Silver-Gold Zed main.
At the start, I started maining Zed, and these days, he is my best champion.
I made this guide to Low ELO players, but I think it can be useful for people with bigger ELO.

I'm going to talk about Early, Mid, and Late game with Zed.
Let's see.

If you have an agressive laner, or a ranged laner, you will have to farm under your turret, or with your Shurikens. At lvl 2, you will have to upgrade your W, and try to give your laner a basic combo (W-Q). You easily can solokill your laner before Lvl 6 either, just try to go for good combos, because if you hit your Q's, there's no chance for your laner to survive, because in early game there aren't any tanks. After LvL 6, you will have to roam, usually to botlane. You easily can get a double kill, or give your adc a double kill on botlane, because your lead is very big comparing to the enemy botlane, even if you are losing on midlane. With roaming, you can easily come back to a lost lane, because Zed scales after he gets the Draktharr.

The meaning of the champion, is splitting. Splitting is very useful, when there is a Drake. If you start splitting at botlane, when there is the drake, you easily can have 2-3 enemy on you, so your team can easily get drake, and objectives.

Zed is pretty useless in late game, if you can't use the champion. If you aren't that fed, you will only be able to kill the enemy adc, but nothing guarantees that you can come out, because of the CC's, so you will have to buy Quicksilver Slash against CC champions. If you are fed, you can actually carry the teamfights for your team. If there aren't any tanks in the enemy team, you will kinda be able to solo carry the match for your team.

Thank you for reading my Low ELO Zed Guide. If possible, I will make Low ELO Guide for other champions, but I want to see that you like this guide, and you like this form.
I recommend to read the notes, because I wrote a reason to everything. Reason to the summ. spells, reason to the runes, reason to the items.
