Heya my name is Hampus "Bringan" Bringert, i prefer Bringan that is also my summoner name.
This is my absolutly first build so im not gonna spend hours on this, Im just gonna show you the basics for Nocturne The Eternal Nightmare jungle. Okey lets start :)

As you can see i have choosen 8 diffrent items, whoot? you can only bring 6 at a time, exactly. Bc in higher level when you are almost gotted maxed and got 2 Phantom Dancers, then you wont need your boots. You got movement speed from the Phantom Dancers. Instead you can buy more damage. So in higher levels sell Wriggle's Lantern and Berserkers Greaves.

As spells I have choosen Smite bc without smite you cant kill mana buff in right levels and bla bla bla...
And as second i have choosen Ghost. You dont have to bring ghost, you can go for example flash. The best thing with ghost is that it have a very good combination with duskbringer.

Okey now to the funny and the most important things, Jungling. Start with buying a vampiric scepter and then walk/run to the wolfs or whatever. kill them with basics and Duskbringer, walk then directly over to the wraths (dunno how it spells) throw your duskbringer and directly smite (the big one) kill the rest and walk to the closest golems. kill them with duskbringer and basics. Now you should have about 100 hp or more... then go back to base, buy cloth armor and 2 healt potions. Walk to mana buff. You should have your smite ready so yeah just kill mana buff and then his smaller friends. Use now a healt potion. Then to wolves again, wraths and then to golems. Use your second healt potion. Now you should have smite ready again. Kill Elder Lizard and his friends. Go base and buy the things you have monney for and yeah then jungle and gank whatever you want. One last tip, I start to gank in level 4 when you have Unspeakabble Horror.

Nocturne is very very good with a Ashe, so a perfect team for me is a Janna, Ashe in bot lane, Nocturne jungle, Mordekaiser solo lane top, and any ap carry mid like Brand, Malzahar, Leblanc or whatever.
