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.
Just a disclaimer: This is my first build, be gentle :). Also, this build works for me, by no means is it the best, or is it 100% complete, however, going up against some of the other MF's, I have taught them a thing or two. That said, enjoy :)
*Note on items: Manamune still isn't available in the mobafire item database, please assume that it is bought right after the Berserker's Greaves. I'll try to keep up to date on this and add it when it's available.
Miss Fortune is actually more difficult than RIOT would have you believe. The best thing she's got going for her is also her biggest weakness, thus the "Glass Canon". Her range makes up for this in some areas, but there are times where its just no helping it. Her passive, Strut, will get you across the map and into position for a gank in no time, however if you get hit once it goes away and you're screwed (all puns intended of course :)). So the best thing you can do is stay behind your minion lines and double up on enemy champions as much as possible.
Exhaust: Could work. If you are a support character on your team, you could rush up exhaust a champion to give your team time to catch up and take him out.
Ghost: Nice to have in case a heel breaks ;)
Heal: Won't do much, if you're taking enough to need a heal, they will finish you off quickly even after its cast.
Smite: If you were to go Jungling, this would be a fine addition, and MF would make a fine jungler.
Teleport: You could probably get there just as quick with strut, but your choice.
Cleanse: If you are at the point where you need this, you're too close to the front get back... And you're probably dead...
Fortify: If you are going to be running around a lot, which you probably will, this will be nice to give you that extra time to get to a turret before it falls.
Clarity: Would be nice, however once you have your Tear of the Goddess you should notice less mana problems.
Ignite: Very complimentary.
Rally: Could work, never tried it.
Clairvoyance: Could be quite nice, your choice.
Flash: You'd probably be better off with ghost
Double Up: This is your skill shot nuke. It's a bit different than most. You want to hit the farthest most minion (after they stop) for it to hit a champion whose close by. Or you could aim from the side and shoot the minion closest to the champion and pray it lands. you won't kill anyone with this, but you'll whittle their health down quickly.
Impure Shots: Nice passive, the only time I activate it is when I'm hitting a turret or jungling.
Make it Rain: Your first skill, unless you went with Double Up. This will slow your enemy and do damage over time. Best part is this isn't channeled, so you can continue attacking or weaving in and out while this is going.
Bullet Time: Timing this is hard. Aim the cone in the direction you want and wait until they are about half way into it, then unleash. Have someone to finish them off and keep them from you though, you have to channel this. I find this is most effective if used over a wall.
This is the first time I've gone down the Offense tree so far, but this seems viable. You might also try moving one point from Alacrity and moving all points from Utility and putting them in Defense for dodge. Not tried this but seems reasonable.
This is just what I had to work with, I wouldn't mind seeing the Quints replaced with Desolation, and Seals with Evading to see how they worked out.
Your first skill, Double Up or Make it Rain, is up to you. However assuming you are trying to get first blood before the game starts, Make it Rain is probably best, because it will slow them down for your team to get there. Besides that you want to dodge back and forth and Double Up against the enemy as much as possible. If you start running low on mana, hold back and only auto attack minnions.
By this time you should have your Tear of the Goddess, and be less starving for mana. Try and get the Blue Buff whenever possible while scouting out ganks or jungling.
Stick at the back of the crowd, you don't wanna take damage and get slowed. Start Doubling Up on champions to get two at a time and use make it rain to escape. If at all possible go into the jungle and try and aim your ult over a wall.
