To some it is known as the Outside, to others it is the Unknown. To most, however, it is called the Void. Despite its name, the Void is not an empty place, but rather the home of unspeakable things, horrors not meant for minds of men. Though such knowledge is lost in modern times, there are those who have unwittingly discovered what lies beyond, and they have been unable to turn away. Kassadin is such a creature. He was once a man forced to look upon the face of the Void and forever changed by what he saw. Once a seeker of forbidden knowledge, he discovered that what he sought was something else entirely. He is one of the few that has found his way to forgotten Icathia and lived to tell the tale, following the scant breadcrumbs hidden in ancient texts. Within a decaying cyclopean city, Kassadin found secrets of the kind that he will never share - secrets that made him quake with fear at the visions of things to come that were thrust upon him. The power of the place threatened to consume him forever, but Kassadin took the only route available to him in order to survive - he let the Void inside him. Miraculously, he was able to overcome the alien urges that went with it, and he emerged as something more than human. Though a part of him died that day, he knows that he must protect Valoran from the things scratching at the door, waiting to get in and visit their torments upon the world. They are only one step away... something to which the appearance of the abomination known as Cho'Gath attests. If you look upon the Void, you can't put it behind you. If you look upon Kassadin, he is probably already there.

Introduction

First things first. Props to killraven and his build "Kassadin: Badass Rift Ninja"
If you are new to Kassadin I recommend starting with his build. This will allow you to learn when you can engage and still make it out to fight again. Once you feel you are having no problem with Kassadin move onto this one :D

*However I still recommend using

Masteries

The only things you are worried about within the masteries for Kassadin is the damage of your R-Q-E combo and how many times you can do it without running out of mana.

This is the purpose of taking Archaic Knowledge in Offense, and every Mana regen point in Utility.

Items

Normally in mid you are going to be against a squishy--and because of this the tome gives you that extra burst on each attack. You will have endless, high-damage attacks due to this with your early game clarity. This will allow you many opportunities to get a kill within the first 3 levels.
Normally by the time you get that first kill you will be buying this flat out for the 1100. You need this extra movement. The MPen is just a great addition.

Depending on who you are against in mid you want to be buying constant, do NOT underestimate the effect these have early-game with a low HP champion such as Kassadin. Everytime you R-Q-E combo you will take down a midding mage to about 50% or less. You will be left with about 50-80% depending. These HP pots allow you to do one R-Q-E combo for each 1 or 2 potions.
All of this harrassment will land you enough money for your Mejai's. From this point on you do not want to die. This doesn't mean stop using R offensively. This is the reason you have. You now have a secondary escape. If you are out ofby now, BUY MORE. 2-3 At all times if possible. This is also where you want to start ganking the lanes. Kassadin is slow at pushing a lane so make sure you've either killed the opponent or pushed the lane up far before you leave mid.
With theyou've grown to become addicted to, you'll spend a lot of time in mid instead of at base. After a couple levels and 2-3 kills you will have enough for your NLRod. This extra 80 AP on top of your 6~8 Mejai Stacks should be enough to take any non-tank champion down to atleast 20% in one combo if not completely.Same as above, though I prefer waiting for the NLR usually.
You should be at 400AP now normally at around lvl 11-13.
THIS is the badboy that makes the difference of a 13-10 game and a 13-0 game. If you are stacking Mejai's and planning on keeping 20 stacks there is no reason not to make a leviathan. 820 HP + 15% LESS damage taken from champions at 20 stacks. Every game that I play with Kassadin I reach 20 stacks on this item. Once you do, you can enter into those 1v3 battles, kill 1 or 2 and R out of there.
This will give you that extra mana boost/regen to allow you to R almost as many times as you please with adding in clarity. I normally like to buildfirst as you will be max Mejai stacks by now and won't want to base. You will build up that extra mana.
More AP and more survivability. You can have more HP than your tank at this point and still hit like a truck with your 900ish AP and 3600 HP.

Unique Skills

You ALWAYS want to mid with Kassadin on this build. The key to staying ahead in mid is to stand in between your opponent and his minions. Kassadin is scary to mid against if you do not have a stun. This will withhold plenty of EXP from your opponent. Once you hit 6 just R-Q-E-R-Q.

Any questions? :D
