Miss Fortune Build
Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
here's another way to play miss fortune as i have. this build makes her damage a huge, and makes ganks very easy. you have mobility build in, so no need there, though the boots help quite a bit. placement is everything with miss fortune, and so using make it rain to cut off escape routes is crucial. this will allow you to make use of your ult to its highest. the ult will help with the kill tremendously, though it is better used in a team fight. farming with make it rain is also a great way to use it, and this is typically how i use make it rain. you cannot initiate a fight, unless you have successfully harassed the opponents first. getting them down with double up is key. remember to hit the minion just in front of them, as double up hits the enemy directly behind whatever you target. with this, i got an ace, and almost took out one of the characters as they res'd, but unfortunately i didnt take into account that there master yi had revive, and he got me :)
but overall this is a great way to play her. good luck, and have fun playing miss fortune, the bounty hunter!
