You're in for a treat for i will be sharing the secrets behind Zed.

I am sharing the secret of zed to the world. Zed's Q Razor shuriken has a hidden passive called "mana god". What this does is the higher the mana regen Zed has the better. His Razor shurikens will deal 30 bonus damage for every +1 mana regen per second. For example +7 mana regen=210 Q damage. Why does no one know this? Well its like a hidden passive such as leona deals 1 less damage to those who wear sun glasses. When i was playing Zed and the refund button was disabled. I accidentally bought tear of the goddess. I was about to add a point on my Q when something blue flashed over the description. "For ever 1 mana regen, razor shuirken will deal 30 bonus magic damage".
He also has a hidden passive called "Unseen ManaBlades". As you hear him quite often say "the unseen blade is the deadliest". Well this passive surrounds his AA(auto attacks). His AA deals Bonus 3 magic damage for every 5 points of mana you have. Mana is displayed on Zed by hovering over his passive. It'll show hidden passive if you have purchased a mana item.
Some say OP? Well yeah it is!

TEST THIS OUT. GIVES HIM SOOOOO MUCH MORE DUELING POTENTIAL NOT LIKE HE NEEDS IT. ZED OP.
