This is a full AD build for Fiora. I get legendary games almost everytime when i use this build. You are invincible when you have full build. You can solo baron easily and kill enemies easily.

Take full Armor penetration runes and also armor and magic resist runes. Then u can deal the max damage at the first levels. This is helpful for getting feeded.

Take full Offencive masteries for attack damage and cooldown reduction.

Start your build with doran´s blade. It gives you attack damage and HP. Then take berserker greaves for movement and attack speed. Then go for more attack speed with zeal and then finish it with phantom dancer. Then take vampiric scepter. Finish it with bloodthirster. Then go fot another Phanton dancer for crit, movement and attack speed. Then go for Infinity edge and then finish of your build with second bloodthirster got the damage and life steal. Then no one can 1v1 you.

First Q (max it lvl 9), then take W(max it second), then take E (max it last), And R(max it soons as you can)

This is very good build but be careful for strong enemys at start. Dont go 1v1 when at lvl 1-12. Fiora will need a good partner to get feeded with. I made up this build, but it is not so wonderful. Just wanted you to get full AD build and get many kills with this :)
