Hello and welcome to my nocturne the Eternal Nightmare Build.
I will inform you to go to my youtube channel and watch the matches on how I did with nocturne. Please read the description.

This maybe is a confusing thing with Nocturne only having 1 ability power skill, but it burns.

I tested it multiple times, it worked perfectly.

Nocturne is all about Critical Strike and Attack Speed. So I thought, those were good runes that fit.

Hybrid, There is almost no Armor for the jungle Hybrid so I take some armor with runes.

I took 22,8,0 just because Utility doesn't work with Nocturne.
On Offense you will probably need Critical strike on Nocturne, attack damage and
Defense, You take armor so at enemy like Tryndamere cannot kill you easily

Hybrid/Jungle Hybrid
I take 21,8,0 which is good for a jungle / hybrid nocturne.

For the Lane Nocturne you NEED a big amount of AD and Attack Speed.

Hybrid Should take what it says!
Jungle Hybrid should take what it says!

Take elixirs in end so you don't waste a lot of money (Hybrid)
Alot of armor and elixirs = Win.

you hit with Dustbringer to get speed, try too fear him with Undespicable Horror, if not reached with Dustbringer use Paranoia. If he gets away by exhausting you, Paranoia on him and exhaust him. While in Paranoia use Dustbringer for damaging before the destination at enemy champion. Finish him off with Undespicable Horror to fear and you will probably have the kill.

Ghost is used for speed to the enemy, or running away.
Exhaust Running away or catch enemy
