Hello, This is my first guide on one of my favorite champions in League. Please leave comments on what I could do to make this guide better or what you would think would be best to change. This is mainly an AD Carry/Off-Tanky build as fiora is naturally squishy. Later on in this guide I will go into alot more detail with why I choose what I did, as it isn't normally what the common 'Fiora' picks.

Pros
High Burst
High Sustain
Incredible in team fights
Cons
Very squishy early game

Okay, In this section I will go through my rune page for Fiora. Keeping in mind that she is a squishy glass cannon.
[*] 9 x Armor Seals
[*] 9 x Magic Resist Glyphs
[*] 9 x Armor Penetration Marks
[*] 3 x Armor Penetration Quintessences
The reason I choose the 9 flat Armor Seals and MR Glyphs is once again, she is extremely squishy early game and just having this extra armor and MR makes her early game just that much more reliable. The Armor penetration Marks and Quints are because of her high burst. Being able to shred through the enemies armor like a hot knife in butter is ridiculous. It's what has always worked for me, I have tried other combinations of quints and marks, and all this armor pen is just amazing.

Okay, In this section I will explain my Masteries setup, 21-8-1.
I have the AD side of the offensive tree covered just to support her high burst needs, the extra 6 armor and 4 MR in the defensive tree along with the extra 3hp/5. and the left over 1 point in the utility summoner spell mastery, as it gives your clairvoyance an extra 2 seconds of sight and reduces the cool down on your flash.

Okay, I will explain the item build and purchase order here keeping in mind this works extremely well with the rune page set up. I start of with the Doran's blade and normal boots. Then after the first encounter as long as you get a kill and an assist you can go right back and buy your dagger and maybe even your Berserker's greaves. This gives you the attack speed to keep your dps up in fights before you get the chance to release your incredible burst potential. After your boots you want to get a Vampiric scepter the early game life steal helps you sustain in lane just that much more. and with a decent partner. You can easily farm while having a ranged zone out the enemies. Going on what normally works for me, if you don't get ridiculously fed you should have your B.F. Sword by 15 minutes if not, you're doing it wrong. x) Then working your way into a Sanguine Blade. The damage and life steal from this, although you can no longer gather stacks it still offers a great amount of potential. That why you get a zeal next, more attack speed. which therefore increases the effectiveness of your lifesteal. After your zeal is complete buy a Phantdom Dancer. Once you get this. You'll notice that you melt the enemies ap/ad carries away. And aslong as you have a decent farm, casually jungling from time to time, ganking every now and then. keeping atleast 1 alter up. this shouldn't be a problem. Next, I work towards an Infinity Edge, The critical strike chance along with the extra critical damage just makes Fiora that more potent in fights. And before you know it, you'll be destroying the enemy within seconds. c: After your I.E work into a Blade of the Ruined king. Now, This item is ridiculously overpowered. I mean, it has life steal, it deals a % of the enemy hp as magic damage AND it drains the enemies hp. I mean come on, why wouldn't you want an item that does that. and just to finish the build off. Get a Frozen Mallet. The passive from this item works well with any ad, it allows the rest of your team to catch up and engage. That is if your aren't bursting them down by yourself. and the 700+ health it gives. >:3 Now that's just lovely. And after your build is complete. just buy the two new Ichors with any extra gold you accumulate and an oracles if there is any need for it.

Okay, Now this might be a tad bit confusing but recently I have discovered just how amazing Clairvoyance is. It gives sight of a massive area for a set amount of time. It shows in bushes even if it wasn't placed inside one. I will show you what I mean in a picture below. And my second summoner spell will be flash. just to help land your Q's quicker allowing you to close the gap between you and enemy.
