I am going to apologize right now for any mistakes, mispelling, and plain noob moves. This is my first guide so I would more than love to hear anything that can improve my guide! plz show some love and leave a reason for dislike! Have fun and let me know what u think! :D

Early game, there isn't very many kill oppertunities. But it is very usefull to harrass with a combo of all abilities. For instance, if you already have all basic abilities (QWE) you may quickly cast Living Shadow at a angle more towards your target,not direct though, unless it is a chase. So you cast it towards the target, then cast Razor Shuriken at them, and then if close enough, Shadow Slash. The combo will make many opertunities for ganking too. Living Shadow also proves to be a good way to flash through thin walls.

Mid- Late game you need to use Death Mark alot. Death Mark basically casts 4 Living Shadows and they mimick abilities for 4 sec. This is a great combo for a way to get to ranged players easily. The ability can also be used on more than one target,if they are in the radius of the abilities you perform. Finally. how to use Death Mark. Death Mark will cause Zed to leap towards an enemy champion untargettable (Simialar to Master Yi's Q move) and 4 shadows will do same, when you reach your target, cast E and then Q at your enemy. They will problably flee, so use the Revonous HydraBlade for xtra damage. Your boots should help with any chases :)
