This is a jungle Nocturne build I made a few weeks ago? But in any case it really gets the job done. get first blood you can carry, get a double and first blood? Well kets just say you will be a true nightmare for the enemey

What I would to do jungle is start at the wolves kill them off without using Hp pots, then go for the wraiths, smite the big one and finish the rest. your next target is the golems killl them and u shud be level 3. next go back to base or cover a lane(cover/gank is a lot nicer) when u come back head for blue or red depending on your play and then do what u did before and finish with the other buff.

Pros

1) With this build you should get nice armor
2) Extremely strong build late game or mid game if you can get a kill
3) high atk speed with ad
4) strong ganker when level 6

Cons

1) weak vs magic( no magic resist)
2) focused in team fights(ult in during the middle of it to prevent that)
3) he is very dependent on his spells early game
4) weak early game vs champions

Well lets see the items.


Beserker's Greaves~ You won't really need any other boots, and the AS on the boots give u a significant boost.

Madreds Bloodrazors~ I honestly think the passive from this is more effective vs champions like Rammus or champions that have high Hp like Mundo and Cho'Gath. The ward from Wriggles is basically only good early game when can easily solo any champion on the enemy team.

Phantom Dancers~ Gives you a nice crit, movement speed which makes up for your Beserker's Greaves and a very strong addition to your overall AS

Youmuu's Ghostblade~ First of all USE THE FRICKING ACTIVE ON THIS!!! Also the crit boost, Armor pen and Cds and okay AD.

Hextech Gunblade~USE THIS ACTIVE AS FRICKING WELL!!!! The slow of this and movement speed active of Youmuu's makes it impossible to run away from Nocturne, this item gives you the needed lifesteal and AD, and for a bouns spell vamp and AP for Unspeakable Horror.

Black CLeaver~ THIS ITEM IS NEEDED ON ALL GOOD NOCTURNE BUILDS. Tis one item has turned 90% of my losing games into victories because of the armor reduction,AD,and AS.
