Hi , i am SafirTouch , this is my Nocturne jungling guide , i hope you will like it , this build is made 100 % by me and i claim the right of it .
I encourage you to use my guide for what it is, a guide. Don't make every decision in the game based on what I say. Use your own sense.

I also REALLY would appreciate ANY comments negative or not or even neutral. :)

(I apologize that this guide isn't going to be pretty as I'm new to the commands. Leave a comment if you notice a mistake)

Nocturne is an amazing jungler , but pretty hard to manage due to his lack of mana ( you will see that he is a mana eater even on late game )

For runes you will goL
x6 Greater Mark of Hybrid Penetration
x2 Mark of Attack Damage

x9 Greater Seal of Armor

x9 Greater Glyph of Magic Resist


I strongly recommend to go as i say , it will amaze yourself how easy you can take someone out .

Quintesences :

x2 of Greater Quintessence of Attack Damage
x1 of Greater Quintessence of Movement Speed

OFFENSIVE MASTERIES as Nocturne is hungry for DMG


Amazing early stats , usefull , nocturne can chase having this masteries set he can also do 1 vs 2 , even 1 vs 3

Situational defense item
Banshee's Veil - this is like a passive of your W + a ton of Magic Resist and Health and Mana, this is almost a core item
Hexdrinker - I love this because of it's Attack Damage and 300 Magic Damage shield
Guardian Angel - Armor, Magic Resist and a Great Passive? At first I didn't think this was a good item for Nocturne but after a few games with this I strongly suggest picking it up. Especially if you have a Suppport champion that can heal.

Then some offense
The Bloodthirster- this is really good if you can keep it fed
Last Whisper- All around decent stats for Nocturne
Warmog's Armor - if your team is weak on teamfights , you should jump on enemy adc having this
The Black Cleaver - this is a pretty nice item to use. The stats and the passive is great to lay down some punishment. It is a bit on the expensive side so keep that in mind.
Infinity Edge - This is another item I looked over. However, it is pretty much core for me now.

This is pretty straight forward. Your Q is amazing for chasing, damage, jungling and team fights. Your E is a CC and CC is VERY VERY important in this game. A fear + a DoT is ridiculous. Your W is maxed last because after Rank 1 I don't find it very useful until late game where you will have your on-hit effects going and people will have more HP meaning you will need to squeeze in more damage.

Start of at Blue buff ( SMITELESS ) keep yourfor the Enemy red buff if your at Blue Team , Keep it for blue buff if your at Purple Team .
Clear wraith's if your starting with RED , Q to hit all the tiny ones. Your passive should clean them up nice.
Clear wolves if your starting at BLUE .
Make your way to Tiny Golems and kill one with Back
Pick up Cloth Armor and Health Potion x 2
Make your way to the large Golem and collect your buff .
Check if anywhere needs a gank
If not go to Wolves
Then Wraiths
Red or Tiny Golems
Red
Wolves
Wraiths
Tiny Golems
Start ganking and clearing as they respawn get your Wriggles and boots (maybe a few wards if you can afford it) and ward dragon + your buffs

Pros

+ High non-itemized damage.
+ Above average clear times.
+ Numerous built-in escape mechanisms.
+ Numerous built-in steroids.
+ Extremely versatile.
+ Reliable ganking pre-level 6.
+ Nearly unparalleled ganking post-level 6.
+ Effective both in Jungle and Top Lane.


Nocturne is arguably one of the strongest Junglers in the Season 3 Jungle. His ganking ability is difficult to match by any Champion; his innate talent for eliminating the enemy Attack Damage Carry and similarly fragile Champions is unquestionable; and his personal set of abilities can often be used both Offensively and Defensively, giving him impressive escape mechanisms and staying power in fights. Overall, Nocturne is, if built correctly, excellent at zoning, kiting, dueling, peeling, assassinating, and ganking.

Cons

- Squishy during early phases of the game.
- Reliant on Blue buff early in the game.
- Consistently focused in teamfights.
- Needs to be fed or farmed to do consistent damage.
- Nerfed repeatedly, reducing viability.
- Requires proper timing and positioning.
- Long Cooldown on Paranoia until level 16.
- Short range on Paranoia until level 11.

However, Nocturne has several glaring flaws that, if exploited, can and will lead to him being shut down. Early in the game, before any real itemization, Nocturne is extremely vulnerable to sustained, heavy damage, and is critically reliant on Crest of the Ancient Golem to lessen the impact of high Mana cost on his abilities. He has been nerfed repeatedly due to being "overpowered," increasing the Cooldown and decreasing the Range of his Ultimate to an absurd degree. While still strong, Nocturne is far from unbeatable without preparation.
