This is only my build for Zed, will add more in-depth chapters later.

The runes, which I chose are my best try yet for Zed, since he needs the armor from seals and the magic resist aswell in later game. You can choose for quintessences flat attack damage runes or armor penetration, you could also take cdr quintessences, it's just how you prefer.
