IntroductionFiddlesticks is one of those champions that can really change the way the game is going, for good or worse. I have loads of experience with Fiddle, and you have to be careful pre level 6, and pre Zhonya's. With this build, you don't have to get many kills, but you still need a chunk of gold to pull it off.
Helps a little, but since it's nothing you really have to keep up with, it's nothing important.
Terrify is a helpful ability for ganks, and escaping. So max second.
Drain is simple max it first for the damage, since it life steals.
E: Dark Wind
Max last because damage isn't incredible even after levels, and silence duration does not extend.
Great aoe ultimate, not much to say other than use over walls, and Zhonya's is a great item to go with.
JunglingStart at wolves, blue, wraiths, wolves, red, wraiths. By then you should be level 4, and you shouldn't have to go back. Go for a gank either top or bot (which ever one has the enemy pushed more), but be careful, when you go in try not to get focused, let the people bait then go in. If you go in at the wrong time you will get killed, because you will be pretty squishy.
Early GameThis one is gonna be quick, Fiddle has a okay early game depending on what's going on. Just don't get cocky and play safe until level 6.
Mid GameAround this time (if your doing good) you should have Zhonya's and be level 6 or higher. You're gonna want to stay around brushes and walls so you can ult in and Zhonya's (pretty simple). Remember to tell your team before doing so, otherwise your gonna wish you didn't bother.
Late GameBy late game, you should be more of a bruiser. Don't get cocky though, not fun if you get cocky. Remember to stay in brushes and behind walls, because if they see you casting ult, they can use any form of hard CC, and your dead.
Team FightsTeam fights are where Fiddle can turn games around. You can just ult in and Zhonya's and the're all dead or low, after Zhonya'a wears off focus the ADC with fear and dark wind. it's better to take breaks in between fear and dark wind, as in when the silence from dark wind wears off use terrify, vice versa. After that mess focus the lowest target alive. If you do all of this and your team can follow up you should have no problem.
Final CommentsSome great champions to have on your team are Nunu, Galio, Amumu. etc anyone with their kind of ults, and strong CC. Some champions he can counter well are: Vlad, Katarina, Yi, Akali. etc anyone who has abilities that can be interrupted or rely on their abilities. Counters to Fiddle are basically anyone with hard CC, to knock him out of his ult channel, and his drain.
