I usually use this build playing in the twisted treeline. This build has never failed me. Make sure you always go top if you play Fiora with this build. Definitely jungle and by level 8 or 9 as long as you have Wriggles lantern you can easily solo the dragon. I've played on teams where because of ****py teammates we were losing 20-9 in kills and because I've jungled i'm usually
higher in level and aced their whole team by myself. Of course for some items buy smaller pieces first. With this build I rarely get to purchase Infinity edge because by then the game is over. You will usually only get up to purchasing the black cleaver. This build is amazing and I rarely lose on the treeline playing on top as Fiora. Good luck and enjoy.
