Hi! I'm SKULLYNX (or Katelyn) and I am a Silver tier Ahri main.
I created this account after leaving league after mid-season 3. I barely started playing again June 2015.
After seeing several games of weird out-of-meta junglers, such as Blitzcrank and Miss Fortune, I've decided to try Jungle Ahri. It's surprisingly viable, and it could work. Hopefully this guide works for you. ^-^

PROS
- Ganks at LVL 3. (Reccomended: LVL 6)
- Mobility
- Charm helps clear camps without taking in as much damage
- Ult (Spirit Rush) has a low cooldown
- Easy First Blood

CONS
- Bad Early Game: Low Mana/Slow JG Clear until LVL 8+
- Could Be Potentially Squishy Against Tanky/Bruiser Junglers
- When your ult is down, you're more vulnerable to a higher chance of death

For jungling, I always start at blue. If you don't, you're going to have trouble for the first few levels and you'll catch yourself buying a ton of mana potions. You could prevent this by taking blue first and clearing the rest of the camps, then get your jungle item and start building cooldown reduction. Cooldown reduction is great for faster clearing and your role in team fights.

You could also steal dragon for your team as your ultimate goes over walls, and if you think you've made a mistake or they took dragon instead, you could always ult back. Don't be afraid of using your ult. Ahri's ultimate has a particularly short cooldown and its really good for ganking and disengaging. Her ult is basically a 3-in-1 flash.

These masteries could be used for any AP based jungler
