Welcome to my Orianna guide. Hope you find this helpful. Not really looking for the big attention but if you like it don't be afraid to share it with your friends.

I play a pretty standard build taking defenses and movement speed for playing against another AP champion in middle. There are multiple paths you can take involving runes. I would take Greater Seal of Replenishment and Greater Glyph of Magic Resist when facing another AP Champion. I take Greater Seal of Armor and Greater Glyph of Scaling Ability Power when facing an AD Champion. I take Greater Quintessence of Movement Speed for personal preferences but taking Greater Quintessence of Ability Power.

My masteries are standard for an AP Carry 21/0/9.

I like to rush Athene's Unholy Grail and the Rabadon's Deathcap. I give's great sustain in Orianna's damage and allows her to remain in lane longer. My next item pick will have to be Banshee's Veil. It gives a good ammount of mr and allows you to block any hostile spell every 45 seconds. Void Staff and Zhonya's Hourglass are popular late game items because 1. You do more damage, and 2. You don't take damage. Nuff said moving on no questions.

The skill build is pretty standard as well, you level up your skills in order: Q, W, E, R.

I take Flash and Ignite. Flash for making plays, and Ignite for securing Baron because I'm a troll.

All I have to say for this build. Try it and have fun. Hope you like it and yeah. :3
