If your not going mid and want to go side lane with your friend, you must go with someone with stuns and someone who can easy protect you, if they are going to gank you.

Sapphire Crystal

+200 Mana, this is the item you are begining with and are very good when you want to use a lot of spells

Health Potion

Click to Consume: Restores 150 Health over 15 seconds., when you beginn a geme this is the second items, so at once buy two.

Catalyst the Protector

+290 Health +325 Mana UNIQUE Passive: On leveling up, restores 250 Health and 200 Mana over 8 seconds. when you can afford it buy it at once, this lets you survive a lot more and stay at mid and get a ton of levels and gold.

Boots of Speed

UNIQUE Passive: Enhanced Movement 1 (does not stack with other Boots), this u must buy after the catalyst the protector or at the same time, this dose thet you can escape spells and help your team-mate and gank easy.

Rod of Ages

+450 Health +525 Mana +60 Ability Power Passive: Your champion gains 18 Health, 20 Mana, and 2 Ability Power every minute (up to 10 times). UNIQUE Passive: On leveling up, restores 250 Health and 200 Mana over 8 seconds. this may you survive much more and stacks up your AP.

Rabadon's Deathcap

+140 Ability Power UNIQUE Passive: Increases Ability Power by 30%, after you are don with rod of ages you shall begin with getting a lot of AP, since your AP is already high because of the rod of ages, the 30% from the rabadon`s deathcap.

Will of the Ancients

+50 Ability Power UNIQUE Aura: Grants nearby allied champions 30 Ability Power and 25% Spell Vamp, this make you and your team-mates get a lot more AP, and 25% spell-wamp, and since Ahri passive grants her spell wamp-when spells hits her targets she can have a huge amount of spell-wamp.

Void Staff

+70 Ability Power UNIQUE Passive: +40% Magic Penetration, this one makes it very easy to kill people because of the magic penetration, and she grants more AP.

Lich Bane

+350 Mana +80 Ability Power +30 Magic Resist +7% Movement Speed UNIQUE Passive: After using an ability, your next basic attack gains bonus physical damage equal to your Ability Power (2 second cooldown). Does not stack with Sheen or Trinity Force. this is a very inportant items, but most likely you will win before you get this item, but this is very good because when Ahri uses her Q spell she first shot a ball thats first dose magic damage forward ( AP ) and true Damage back, ( AD ), so what i meen is that this items dose that is dose exstra damage both forward and back again.

Rylai's Crystal Scepter

+500 Health +80 Ability Power UNIQUE Passive: Dealing spell damage slows the target's Movement Speed by 35% for 1.5 seconds (15% for multi-target and damage-over-time spells). this you can change with the rod of ages if you want to get even more AP

offensive masteries

I take offensive masteries to make my bust do more damage and to kill them faster.

Ulti masteries

I take ulti masteries to make spells shorter CD.

I take ignite Because because it dose a ton off damage and makes an easy kill, or FB.
for the second summoner spell i take flash to make an easy escape, but you also got your ulti that works like flash but that you can use tree times before you get it on CD.

you can also take exhaust insted of flash, because of your ulti since it works like flash.
this can make that you can take faster champions they you and get an easy kill.

Why not clarity? my Answer: i begann with clarity when i first begann to play as ahri, but i saw that i never used it because i did not use much mana on my spells since i got the Rod of Ages, thats make me get both helt and mana each time i lvl up.

Unlike other foxes that roamed the woods of southern Ionia, Ahri had always felt a strange connection to the magical world around her; a connection that was somehow incomplete. Deep inside, she felt the skin she had been born into was an ill fit for her and dreamt of one day becoming human. Her goal seemed forever out of reach, until she happened upon the wake of a human battle. It was a grisly scene, the land obscured by the forms of wounded and dying soldiers. She felt drawn to one: a robed man encircled by a waning field of magic whose life was quickly slipping away. She approached him and something deep inside of her triggered, reaching out to the man in a way she couldn't understand. His life essence poured into her, carried on invisible strands of magic. The sensation was intoxicating and overwhelming. As her reverie faded, she was delighted to discover that she had changed. Her sleek white fur had receded and her body was long and lithe…the shape of the humans who lay scattered about her.

However, though she appeared human, she knew that in truth the transformation was incomplete. A cunning creature, she adapted herself to the customs of human society and used her profound gift of beauty to attract unsuspecting men. She could consume their life essences when they were under the spell of her seductive charms. Feeding on their desires brought her closer to her dream, but as she took more lives, a strange sense of regret began to well within her. She had reservations about actions which never troubled her as a fox. She realized that she could not overcome the pangs of her evolving morality. In search of a solution, Ahri found the Institute of War, home of the most gifted mages on Runeterra. They offered her a chance to attain her humanity without further harm through service in the League of Legends.
