Hey everyone. This is my first guide on moba. I'm still in the process of possibly refining this, but I wanted to put this out there because I feel that if people tried out this build, they'll realize that Diana is so OP. For now, this is just a build. I'll add explanations later.

This rune set up is ungodly good on Diana.

The marks for attack speed greatly enhance her passive. Combined with the items for the build, her passive will be eating away at the enemy champs' health.

For the glyphs and seals, I went with the standard flat armor and per level magic resist because Diana is a melee character essentially. She gets in there and needs some defense.

For the quints, I gave her two, yes two movement speeds quints and one ability power quint. This helps her throughout the match if people get foolish enough to think they can mess with her, and run away.

I went with a 21/9/0 mastery build. I went with the focus of AP down the offensive tree because Diana is an AP champ. I took 9 points in the defense tree because being a melee character, Diana needs the points in armor, magic resist, and health buffs.
