Hello! This is my First guide so please enjoy, and feel free to comment below on anyway it could be improved. I am currently a rank 4 Nocturne and have been playing him since late February. I get an average of 13 kills a game, with 25 kills being the most I have had in one game. Over my time with Nocturne I have tried many different tactics and have here my most perfected way of playing him.

Although it might be fin to build attack speed on Nocturne I advise against it. His w already gives you a considerable attack speed boost, so attack speed is covered that way. With this in mind, never build poachers blade, not only do you not need the attack speed boost, but you also don't need the AP.

Always start at Gromp, regardless of what side you are on, UNLESS the enemy jg has a high chance of starting with red. Ward the enemies red 15 seconds before it spawns, then go back to your Gromp. Kill your Gromp and your blue and pop both red pots then go to your opponents red and hid in bush until he gets there and gets red down to low health. Then smite red to kill it, terrify your opponent and use your Q. From here you will either force your opponent to flash or kill him, either way now you have his red and a great advantage. If the enemy starts at red, do the same thing starting with the Krugs then your red, then over to your opponents blue and use the same method. Do not try this against very strong early game junglers like Voldi or Udyr. From there you can either gank top or proceed to your own red.
