This build is still underway and will be updated every day or two!!!!

Pros:
good jungle or lane
easy to learn
lots of damage and cc
Cons:
squishy
may get targeted alot
mana dependernt

Ignite: Targets a single champion dealing 50 + (lvl x 20) true damage over 5 seconds. Also reduces the target’s healing and regeneration by 50%.
Very useful for the last little bit of damage needed for the kill!


Ghost:Your Champion ignores unit collision and moves 27% faster for 10 seconds.
When you need to catch up to speedy enemies activate your ghost and get that kill


smite:Deals 420 + (lvl x 25) true damage to target enemy minion or pet.
Although this doesn't work on champions it is amazing for jungling and for helping later in the game against super minions

With fiddles you will need ap. The more ap the better. If you are fed however i suggest trying to max ap to over 1000 by buying a rabadons deathcap/will of the ancients/ and everything else archangels staffs.
if not fed then try the build i put up making sure the first three are bought is a sure way to get people to be scared of you especially with combos.

First thing you will need is to get drain. Drain is especially needed for mid, if you are laning with someone who needs your help to get kills at first then get fear and fear them while your teammate goes in for the kill.
Early game harassment. Start off trying to get mid if your team doesnt mind. you will want to drain your opponent anytime they come out of there turrets range so you get exp for minions while they are getting scared. After level 2 you will have terrify and drain. Use terrify to fear the opponent and quickly cast drain taking out a good amount of there health and giving you some back, this will make most characters need to recall before you. There are however some characters that won't be as affected and you may have to be more careful around.
Combos
combos are always important if you don't have a op melee character. For early game fid combos use dark wind followed by terrify and drain. if you do not have dark wind then use terrify and drain. Later in game once there are more team fights the combo gets more interesting. Try to gank them from behind by doing the following. Wait for them be towards your territory fighting against your team. Go through the river and try your best to get close enough behind them so your ult will damage them but they cant see you. Once your in the best spot for this do the following: First determine who you want to kill the most out of the group(either the strongest or most hp) cast your ult and immediately cast dark wind and terrify on your target while trying to maintain a good spot for your ult to continue to hit enemies. As soon as the enemy is feared use drain on them and watch there hp melt away.

Farming with fiddles can be tricky sometimes, with him you will want to go mid as soon as you get a good feel with him. You will want to harass your opponent as far away from the minions as you can but close enough that you can run and also get the exp. while farming in mid or even laning make sure that u can use your range and wont be messed up when not behind minions. You will also want to be worried about ganks since fid isn't a tank and can be very squishy.

fiddles jungle.
Fast and easy
Start off by getting a leash on blue, after that head to wolf camp. remember to drain the biggest enemy first and use your e when available. next head over to wraiths kill the blue one then finish them.
next golems or red buff, either will work just depends on your mana and how long blue buff will last

Who ganks?
The best gankers are ones with Crowd Control, Area of Effect, or stealth abilities. Ashe, Fiddlesticks and Shaco are perfect examples. They can all get around the map fairly quickly , Shaco can stealth in and kill anyone within seconds since he's able to do massive damage from behind, Ashe can use her ultimate ability to stun an enemy and frost arrows to chase them down, and Fiddlesticks is stacked with Crowd Control and an insane Area of Effect ultimate. There are many other heroes who can gank really well, listing them all would take up too much space and to do so would be pointless, the best way to learn is from experience. Everyone plays differently.

When to gank?
when your team is needing you to, if you see a good shot at getting a kill or two
make sure when you gank you will do what you were hoping for whether it b get them to back off or even kill them. dont get yourself into a chase and get caught however.

Very important for you and your teammates!!!
If you are a jungler you will definitely need to buy these for your team and help them out.
Where do you want to put these wards? and what wards to get?Anywhere there is green is mainly for the whole game, if its near your lane then try to ward it when necessary or needed
anything in blue is mainly for if you are jungling or if they try to steal your buffs repetitively
and red is for if they are ganking you pretty hard and need it


Now for if you should get sight(green) or vision(pink) wards.
if you are going against opponents that can go invisible then you will need pink wards sooner or later. if the people in your lane dont have any ability that makes them invisible for a few seconds then dont waste your money and instead go with green wards until you need the pink. if the enemy team has no champions that can go invisible then dont buy pink wards, they would just b a waste unless you used to find enemy wards. but instead of buying wards to find theres just get an oracles elixer and use it to find and destroy their wards
