Hey guys! This is my second build/guide, and it's about Kassadin, the Void Walker.
This guide will be an in-depth guide to crushing your opponent in mid with ultimate sustain and harassment.

Why play Kassadin?
I tried playing Kassadin once and he's extremely fun! He's great for more inexperienced summoners as well as more experienced players. Kassadin offers great mobility and CC. He can Riftwalk (His ultimate, which is a better version of flash) out of any situation and into any situation.

Good luck Summoners!~

Pros:
Fun dance
Great mobility
Uses ultimate to make up for range
Extremely powerful autoattacks for an AP
Built as an Anti-AP
Extremely fun
Team CCer


Cons:
Often banned
Melee ranged
Long cool downs

Why these runes?
Kassadin requires quite a lot of magic penetration to pierce the magic resist of the opposing enemy. He also needs some AP and mana regen.

This is Kassadin's skill sequence. His main damage source is his q, so up it first, then his e, w, and obviously focus upgrading his ultimate.

Upgrade them in this sequence:
If available upgrade:> then
If available upgrade: > then
If available upgrade: > then
If available upgrade: .
