A Guide how to play against Zed
I'm confident to call myself experienced with and against zed. I saw a lot of people struggle playing against him, so I decited to make pretty short Guide.
As an ap mage I highly reccomend taking Armour Yellows. If you are not so confident enought, take Armour Per Level Blues. These runes will make you a lot tankier after a few levels. It would make any assasin feel abased.
If you're wining, you can buy whatever you want, you might even rush a Lich Bane. If you're losing or equal, I highly recomend going for Arm Guard in to Zhonyas, second option would be - Catalyst in to Rod Of Ages.
At first levels Zed is very vulnerable, you must take advantage of it. Zone and make him choose between poking you and farming. Don't stand near low health minions, becouse he will be able to last hit and poke you at the same time. Try to push as less as possible, but at the same time don' let him push, othervise he will be able to poke you much easer and have a chance to roam.
You should know then Zed has hes Shadow (w) up. Pretend that you're going to last hit a minion and make him waste hes combo, only then last hit the minion. In this case, if/then he trys to farm, punish him, even if it means that you're going to lose a minion or two, for chunking 1/2 of hes health. Eventualy you force your opponent to base or it's going to result in a kill. Another choise would be - going all in after you dodged hes spells.
I don't reccomend fighting zed without Zhonyas, RoA later on, especialy if you aren't ahead.
. The only reason to build zhonya is to make up in defense because you just can't play offensive against a zed or you will get killed. And even tought, Zhonya now costs 3500 gold wich is almost impossible to get before the enemy Zed reach level 6, and Zhonya is litteraly the ONLY counterplay mages have against Zed.
or whatever other assassin jumps on me under my tower. They try to burst me down, but I manage to stun them and kill them before they can leave tower range because they used their gap close to get to me thinking they could get me.
