Hi all n welcome to my guide on Fiddlesticks as a jungler. This is my first attempt to write a guide though i play LOL for quite some time so feel free to judge.
Jungling for Fiddlesticks is as natural as breathing because of Brain. No matter if you are level 1 and no one pulls the blue Golem for you, its almost certain that you leave the site intact with level 2 and the buff.
Now all you have to focus on is how to get stronger and be able to land a fatal gank...

Pros

• Epic jungle efficiency
• Early gank ability cause of lvl 3 Terrify
• Team silence and team slow just with E by the time Rylai's Crystal Scepter is complete :O
• Devastating ultimate - Once catch someone in it and cast Terrify it's almost impossible for him to survive

Cons

• Very squishy without Bountiful Harvest
• Tend to get focused because of his ability to disable a whole group
• Gotta sense the map in order to land a proper early game gank

My rune choice is the same for all AP characters except for the new Spell Vamp quintessences witch i believe make Fiddlesticks even more durable and early game independent of returning to base unless you have to shop.

I keep in mind that squishy is the main defect Fiddlesticks has to deal through the game. That's because i develop my defense mastery tree to the end taking almost every ability that will grant him health and protection from incoming damage.I think Tough Skin and Bladed Armor are ideal for any jungler though Enlightenment is a nice alternative if waiting for Crowstorm is getting on you.

In most games i take Terrify asap to get a full gank capability though i rarely attempt unless i get a second rank on Bountiful Harvest. From there on i keep in mind that Bountiful Harvest and Terrify need to be maxed first because these 2 define me as a ganker. If the game needs you to lane for a while, try getting early one more rank on Reap as it can be used as a skill shot.

Smite is absolutely essential to any jungler though Fiddlesticks can easily farm almost every creep without it. Smite is against buff stealing and fast farming in order to quick gank.
Flash needs no explanation. It's the ultimate escape tool for any character and the only for Fiddlesticks if Terrify is on cool down.

I try to get Rod of Ages asap because its my first countermeasure to the fact that Fiddlesticks is a squishy champion. Once i get my second Blasting Wand i am strong enough to deal some serious damage. By the time Rylai's Crystal Scepter is complete, Rod of Ages has grown your hp to that point, that you can initiate a 2vs2 or 3vs3 team fight.
Rabadon's Deathcap comes 4th to boost AP to >300.
From that point on you can develop according to current game needs...In most games by that point I am No1 priority for enemy team to kill so i choose to upscale my defense with Zhonya's Hourglass and Guardian Angel. Feel free to pick a more magic resistance oriented item like Banshee's Veil or Force of Nature if enemy team's AP carries are after you or Thornmail if enemy has a fed DPS char.

As i highlighted on Pros / Cons chapter, Jungling is all about picking the right time to gank. Team co-operation and good sense of when and where to gank cannot be sustained by any built. Thank you all for reading and please leave your comments.
