Hey this is my first guide.

This guide is for Nocturne and i've been using it for a while and has worked out pretty well for me. Basically this build should give you a pretty reasonable score in 5v5s if used well. Although the selection of runes are a bit complex, this will allow your Duskbringer attack to do more damage and also keep you alive for as long as possible. It also allows you to take down tanks easier later on in the game with the armour penetration marks and the high damage you will be dealing with the items bought. This build can be used in mid laning as well because of your higher damage duskbringer.

Before Nocturne, people believed that dreams were figments of their imagination, meaningless images that flashed through the mind when one slept. This belief was put to the test when a rash of sleep-related incidents started afflicting summoners of the League. Some would wake up screaming, terrified and beyond consolation. Some could not fall asleep, slowly going mad as the nights ticked by. Some simply never woke up. Physicians were baffled until a Field Architect happened to pass out next to a nexus on Twisted Treeline. Witnesses said he cried out once and then stopped breathing. Immediately after, magical energy arced out from the nexus, and Nocturne appeared.

Nocturne did not take his introduction to this world kindly. He slaughtered everything he could find before summoners were able to magically confine him. After a period of intense study, League experts divined that Nocturne hunted summoners in their sleep, attacking them in a place where their magic was useless. This seemed to be his only purpose. The families of the victims demanded justice, but League officials were concerned that death might only return Nocturne to the place from which he came. They bound him to a nexus fragment, trapping him in the physical world. As punishment for his crimes, they allowed summoners to call upon Nocturne in the League matches, bending his will to the summoners he hates and creating his own personal nightmare. League scholars don't know whether he truly came from the plane of dreams, or whether there are any more like him. Some theorize that the summoning act affected summoners' subconscious minds, luring Nocturne to them in their sleep. Perhaps the most disturbing theory is that Nocturne is a person's nightmare come to life. If this is true, they wonder, who is the dreamer?
