I think fiora is one of the strongest champion in LOL.Her burst of speed and ultimate are so OP.Thats why ı am playing with Fiora and I made a build guide.I think fiora is a fun champion.If you try this build meticulously I mean ıf you buy ıtems in sequence you will take easy kills and you won't die.in early game ,Fiora isn't strong I think so wait 6 levels and afterly join fights.

Differences are just I changed tiamat with black clever

In mark, I selected critical damage runes .Because Fiora needs this runes too much.Already I started with crit chance because in early game fiora can crit damage easy.We are buying AD items so we need critical damage our purpose is this.These runes help me for this purpose.

I selected attack speed in seal.Fiora needs attack speed too much.Because we are going to buy only 1 phantom dancer and we will buy 2 bloodthirster.for more lifesteal we need attack speed.

ı selected attack damage in glyph because we need damage for early game.

Lastly I selected critical damage again in quintessence.As I said Fiora needs critical damage too much ( in this build) and these runes help me really much.

21-9-0 its fine.Because you need health in early game and starts with more 30 health is really good.and afterly our champion is ad so I selected critical and damage masteries.

Pros

hit 1.3k+ damage after this build
good turret destroy
gorgeous e skill
incredible w skill in late game against ad (tryndamere,caitlyn,sion..etc)
super powerful ultimate
after fed nobody can kill fiora
really fast with e skill
good farmer

Cons

Not very powerful in early game
she hasn't got any ranged skill
Only melee

I started with brawler's and 2 health potion.Critical chance really important for Fiora.After that I buy berserkers and zeal.Because We need attack speed.And I need wait little bit and I will buy B.F sword, Bloodthirster and then finish phantom dancer.then infinity edge again bloodthirster and lastly taimat.I selected taimat because taimat is a good item for fiora ultimate.

If you try this build you won't die after 15 mınutes.And ı am sure you will thanks to me :=)
