So u have bought Nocturne and decided to Jungle with him. Great choice, now lets get started...

Pros
- great dmg output
- fun to play
- ult has ridicolous range + many uses
- fear and build in banshee
Cons
- squishy ;D olaf and trynda will laugh at you
- ult has long cd
- fear inst instant u need to stay in range

So the runes i suggest are armor pen reds flat armor yellows and attack speed blues with flat hp quints.

I think thoose would be the best choice for runes but you can change them to your liking. Jungle works also with other sets of runes. (i play him with armor per lv yellows cause i hadnt had the oppertunity to buy flat ones yet)

The masteries are pretty standart 21 0 9. If your gonna jungle always take improved smite and increased buff duration.

not gonna comment wriggles lantern you just need it its the jungle item.
3 movement speed boots add well with your movement speed buff from Duskbringer helps you chase down gank faster and jungle faster. (exchangable with mercs or beserkers)
after that go for BF Sword and Phage. they provide the much needed survivability dmg and slow target on hit so you can be sure that no one is gonna escape.After that finish your infinity edge and build frozen (if anybody wants to try you could build tiamats after that). after froyen mallet start your trinity force with sheen and zeal. after that you should be able to jump in and deal aroorund 1100 crit aoe dmg on first hit = double kill most likely.

Not much to say here start with W then Q after that Q. i personnaly find it important to get atleast lv 1 fear befor lv 6 because as a jungler you should be ganking a lot and that fear will help you. after that lv up ulty when you can.

I take ghost and smite. Smite you really need for the jungle and ghost helps you in tough sitiations.

So unlike in the summoner spotlight i dont start at blue buff i feel to squishy and its far to dangerous to get ganked (my oppinion). So how do i jungle? i smite big wraith down (oneshots him at lv 1) then i go to the golem camp kill them after that wolfes. so now you are lv 3 the cd of smite is back on again. You w8 a cople of secs to get your passive back on and go for blue buff at lv 3 you should be able to kill him without problems nuke him with smite again. After that back to base buy boots and pots . Get red with smite again. Normally the jungler ganks top but in that case the shortes way is either bot or mid. after that go back again get madreds (hopefully you got a kill) and repeat the whole cicle again try ganking as much as you can, get kills push towers.
If your teammates arent complete ******s you should get pretty fed and own mid and late game.

Oh yeah buy wards and use your active from wriggles your the jungler thats your job !!!!!!!! At lv 9 you can solo Dragon better to get a bit of help though.

I wanted to add a bit more here but somehow i cant rly think of much. So try asking someone of your team to play TF amazing combo with double ult. Dont be too Agressive in team fights the opposite team will try to focus you down remember you are a squishy ghost :D. IF you have a problem with ranged champs or mages use your ult in the midlle of the fight and two hit that pesky ashe :D

So thats how i play Nocturne pls rate and Comment i am open for suggestions. NO HATE just constructive critisims pls.
