Ok guys, so this is the first build I'll be making, so don't massacre me cause i'm no LOL god. I'm also not writing out some huge shpeal, but this build works well for me solotop or basically anywhere else. As I have played her more, I have had increasing success as a solotop besting 2v1 or 1v1 by patience. A lot of Fioras that I see run and attack as if they were gods, and then they end up feeding. I turret hug like a boss in a 2v1 and wait for them to make a mistake or my jungler to gank. with that strategy I have successfully been able to win most 2v1 fights.

I'm a noob, don't know what runes work best cause I don't own many, but I use a lot of armor pen, straight up armor, and per lvl magic res with armor pen quint.

I chose the items I did because i like being able to attack and destroy quickly. These items make a nearly impossible to defeat 1v1 Fiona. Just be careful as you are a main target in teamfights. I would only possibly change out some AD for a Frozen Mallet if you are feeling too squishy.

So yeah, clean and simple, fight aggressively if you know its safe and with this build I tend to crush my lane, best of luck.
