First of all this is my first guide build so leave comments for any suggestions please!

Fiora is a mildly hard character to play. Fiora is played top lane, but you can opt to go bottom. She has very good abilities, such as her free AD and attack speed, but the thing that makes her special is her ult. Her ult is capable of getting a PENTA, if performed correctly. She is an ADC, and relies on total AD. MAKE SURE YOU FARM.

Fiora build is simple. You want to first go for the 15 AD and 80 health, so buy the Doran Blade.
This enables you to have an advantage over the oppononent, because of your W. Lets say you have 75 base damage. Build you W, so that's 90, and then the Doran's Blade adds another 15. That equal's 105 Damage, already 2 minutes in the game. You then want to build towards Berserk Greaves. This gives you attack speed. Next, build towards the Tiamat. Use this to farm heavily,and use the active that has a cd of 10 seconds. You then want to build towards a BloodThirster, and than another one. This gives you a lot of LifeSteal, which you need. Next, build towards the Phantom Dancers. Then go for the IE.

Ok. This is fairly simple. What you want to primarily use when you engage is your W, then q and q and e. Then of course..... ULT, and use your Hydra's active. You can also use it if you are chasing someone but you can't kill them, or you can use it to get last hits. I usually keep the Hydra on my 3 key.

If you are fed late game, you can basically solo baron if you have almost a complete build. (I have done this before, when I went 25-7-10). If you are going for a kill and want to be sure to get it make sure to ult. Also, ALWAYS ULT IN TEAMFIGHTS. Thanks!

Make sure to copy what I posted, STRAIGHT AD on the runes. Mostly build ad on the masteries but you'll have a few left over so you can opt to build whatever.
