this is a good build for nocturne it is a good build for causing damage,
its not for jungling only for lanening, it does good damage en sometimes crits,
when you play noncturne you must play him defensive and aggresive.
nocturne is a old champion but still is OP,
if you really want to get good you got to have a good supporter with you on a lane,
and the items that i chose are good for damage and i chose Banshees veil so noc gets extrahp,
so he isnt squicy like teemo or something like him,
and over the items you would probobly just give them a view hits till they die,
and in the build i did veery much items so you have always items that help you when your:
ganking/supporting/solo-ing/ team fights and many more like those.

i hope you guys find it helpfull,
ive i got votes i would make more builds,
not only from not but other champions,
Good Luck With The Build!
And Have Fun!
