This is my first build, and I hope it's good for you guys. In my opinion, I think nocturne is a better laner, rather then a jungler, if you can get those early kills, then you will dominate the rest.

I start with a long sword mainly so I can finish up my Brutalizer faster. Once you have the Brutalizer, you will be doing more armor penetration, as well a good cool down reduction early game.
