Welcome to my Nocturne-Guide.
First i want to say that Nocturne is a really nice AttackDamager, so it´s important to play him with runes which supports this. I bought AttackSpeed runes, because i think it´s the best way to start with Nocturne.
With the Dagger at first u had 1,0 AttackSpeed, after that just use my Build.
In the endgame, so if u bought Stark´s Fervor, u should sell your Wriggle´s and your Shoes. With the money buy a second Bloodthirster and a second Phantom Dancer.
If u followed my Build and bought those 2 things u have:

2,4 AttackSpeed
87% Crit
50% Lifesteal(exclusive the 2 Bloodthirsters.. If they are full u have 70% Lifesteal)
and ca. 250 AttackDamage.

I know, most people will say its silly to go like this build, because u are 3-Hit or something like that. But if u play Nocturne like this and don´t go in a Teamfight as first u could win the game in a desperate situation.
Nocturne is very nice to push a lane while your team and the enemies are fighting mid lane.


And now... enjoy Nocturne :)
I hope this Guide could help you!
