Ahri is a super good Mid Champion if you know how to use her well. At lvl 1 i take the Orb of Deception because it's a good range attack and hits multiple targets, and also gives you lots of Health when your Passive is triggered. If it lands a hit just at the turning point it does tons of damage.

The masteries i choose, was to making her able to regain mana and be able to do lots of damage. Making her able to do some damage dealth masteries is to make the item selection more flexible than only AP, this opens the posibility to use Lich Bane to give you more mana, speed, ap and your basic attacks deals more damage.

These items are for pure damage with your attacks, you can ofc use Souleater to get more AP and Cooldown, but i like using this build, because i've so far only won with that build.

Since fox fire doesn't deal that much damage after the first one has been fired and it hits diffrent targets, i take it at lvl 4 and max it at the end as the last skill. I first take Orb of Deception since it's good for doing damage and it's good for healing. When passive is triggered you gain spellvamp and since Orb of Deception hits multiply targets you gain more Health back. It also does True damage on the way back after being shot out, which does lots of damge. i take it at lvl 1, max it at lvl 9. Charm is spell i take on lvl 2, since it is very effective to taunt the enemy, and make them move slow, so you can hit them with Orb of Deception without them dodging, which gives you an oppurtunity to kill them. Her Ultimate, is very usefull for engaging a target, or flee from the battle. The ultimate does lots of damage, and can be very effevtive if you use it right with the skills you have, use it wisely and you can kill a target very fast.

I like to use Flash, as an extra spell to flee with, and it's also good for dodging and chasing.

Some people might like to use Ignite, but i like to use Exhaust since, in a 1v1 fight you can make your opponent weaker and if he tries to run you can use it for slowing, and when they're slowed it's easier target for your skills like Orb of Deception and Charm. You can also use exhaust to make opponent slower then use Ulti to dash around them to damage them without them being able to catch you.

Ahri is a cool and strong AP assassin which can dodge attacks or flee in other words she's flexible, and she does lots of damage with her skill shots.
