This guide is a work in progress, and any feedback on existing sections is appreciated. Please do not downrate on the grounds that something has yet to be added; odds are that I'm getting to it. Eventually, I intend to expand the guide to include an AD carry / solotop section.

This guide, unfortunately, is not be pretty. It is, however, be full of sound advice based on my play experience with Fiora, particularly in the jungle. Currently, it's being debated whether or not Fiora is worth jungling, as she has a below average clear time, and is dependent on cc from laning champs to start ganks. It is my opinion that she is not only viable, but extremely fun and rewarding when played correctly. I digress.

Runes

Fiora is a simple girl. She likes long walks in the forest, pretty pictures, and demolishing any noob stupid enough to try and 1v1 her without backup. She dislikes being focused in team fights, dying, and opponents who stack armor. To these ends, we rune her to add armor pen as much up-front marginal survivability as possible.

"But Tenor," you might say, "that's what Fiora's R is for! If I get focused, I just push that magic button and start flying around the fight, footloose and fancy-free!" You would be right, of course, but only halfway so.

There are several problems with the proposed reliance on R to save your spandex-wearing butt in a team fight:

1) when the fight engages, you're an easy target for cc'ers, since you have to be in melee, and can't ult while stunned, silenced, or rooted. You have to outlast the cc (and accompanying focus fire) before you can pretend to be Nightcrawler.

2) have you seen Fiora's ult before? She doesn't finish it wherever she started from. Once your ult is over, you'll find yourself smack dab on top of the initial/final target. In many cases, this means you are right in the middle of the enemy team, and suddenly without your precious aggro-drop. Fiora dislikes dying, and a few survival runes go a long way towards making it out alive.

Masteries

Masteries with Fiora are also pretty straightforward. As a jungler, you want the requisite 9 in the Defensive tree, and as an AD carry, a pretty standard 21 in the Offensive tree. Note that I recommend Demolitionist over Lethality, as this build foregoes crit in favor of pure ad and a few on-hit procs.

The jungle route I use for Fiora is pretty standard, and very easy. What's important to remember when jungling Fiora is that E only lasts 3 seconds, and W seems to reset her swing timer. So when engaging a new camp, be sure to get a first hit in before popping W and then E, to maximize upfront damage. Also, if you have blue, don't be afraid to blow E for the last few hits in a camp. Getting three swings in will give you a 9 second runspeed boost, and lower your total clear time.

Start at Blue with a leash from mid. Be sure that when the big scary guy switches to you, you correctly time your Riposte to reflect his attacks on CD. Smite to finish him, then clear his camp.

Next hit wolves, starting with the big guy. Get a first hit in, then immediately pop W and E. The big wolf should go down in no time flat, and the little ones should follow.

Hit Wraiths next, and do them the same as the Wolves.

Red buff is your next camp, and Smite should be back off cooldown by the time that you need it to finish the red creep. Do so, with gusto.

Golems next to hit level 4. Now, take a look at the lanes. Are any of them pushed? If you've jungled well, you should have most of your health, and be in a fairly good position for an early gank if one presents itself.
*Generally, ganks this early on Fiora won't work unless the lane champ has some sort of cc and is pushed back to his tower, but you never know. Just remember, you don't have boots yet, so you won't be able to chase terribly well.*

If you do manage to gank, you can B immediately after to make your first buy. Otherwise, continue back on up to Wraiths and Wolves and then B.
