I played nocturne as soon as he was released, my first game i went 25-3 and did amazing throughout games, I was impressed. But at the same time I thought, this is so op. So i play nocturne just to piss people off and crit for over a thousand. His ult is amazing and it's probably one of the coolest champs out right now. This is my first guide, i hope you enjoy.

Pros:
High Damage
Insane Ultimate
Fun as hell to play
People fear your sexy shadowyness
Great Chaser
Can initate ganks perfectly

Cons:
Low hp
Not much CC
Targeted first

I got straight up Attack damage, crit, and attack speed. And HP Quintessence's. I did this to be total rape at the start of the round. You will most likely get first kill, or even a double kill. Once you get that you will be fed through out the game.

I take ghost and exhaust just for chasing purposes. You can take flash too, but don't recommend much other summoner spells. Teleport isnt necessary because of your ultimate and it also has a very little cooldown.

You are the initiator. You just sit in the bush and wait to use your ulti when your team is ready. Once you use your ulti do your "Q" Skill than "E" skill to fear them you are for sure go ing to kill your target.

The reason i go jungling is because it really isnt necessary. Once your level 10/11 start going for red buffs, and maybe even blue buffs if no one needs them on your team. You can jungle with Nocturne and be successful, but i'd way rather harass in lane.

I hope you enjoy my guide, I hope you are just successful as I am with Nocturne. Please vote, but at least try it if you are down voting it.

Thanks!
