Nocturne: is an melee assasin who deals really high damage to his opponents and due this build he has a really huge AD and AS which helpis him to be a great dueler and a great dominator for his team.

Pros
+he has high damage
+high sustain
+great jungler
+fun to play with
+good early game
+great ganker

Cons
-hard to master
-item depenant
-easy takedowned if not mastered
-sometimes focused
-i havent any cons left..:p

I take Smite for jungling no matter what
Smite and Flash is the most perfect choices for nocturne because his has no natural escape mechanism

First I take cloth armor and 5 healh potions then I continue with wriggle's latern for life steal and heart of gold for more gold gain.After I continue with frozen mallet to take advantage my Q abillity and Randuin's Omen Bloodthirster and last but not least Trinity Force

For to start a team fight concider to have a baron buff first..then aim to a AD or AP carry and ult him with Paranoia and with your team kill the rst of them and head for the nexus if plausible....

Thanks for your time and i hope i helped you with my guide for nocturne if you have any sujjestions leave a comment and i will hapily reply .But please dont start to swear about anything...
