@Haya Ji
First of all, thank you for leaving your comment with your opinion on the build, it means a lot to me.

Let me start out with the runes, the MPen runes were supposed to be armor pen runes, my mistake, I will correct it.

Jungle routes, everyone has tried tons of different routes, I haven't done that yet, but I will try to do what you said and I'll post here the result. I only posted that jungle route because its easy for new junglers, and I was able to level up like the other players in lanes.

About lane play, I like to play lane because of Nocturnes great early damage, awesome pusher.

Finally, items thats my actual preference, I haven't tried out many items yet but I will try to make another item build for him, although this one is pretty cheap at the beggining and gives him great damage for buying those most expensive items.

And as I said, the build is not finished yet, I'll keep updating with more tips/tricks and items.

Fail. First off, your jungle route is not built around your passives potential. Try starting at Wraith camp with Q, youll clean the 4 minions in 2 strikes with Smte on the big minion, then Q and auto attack on the rest. If you start here, then wolf camp and only then golem camp, you have lvl 3 when many times others are still passing to lvl 2. hich means you can easily gank if they overextended and get your first blood in the first 5 minutes.

Secondly, it strikes me as something ridiculous suggesting people to get a thornmail for Nocturne. You are squishy as hell. The true power of a thornmail aint the armor, its the dmg it deals back. Since you will be dead in 3 or 4 hits from... lets say a renekton or any tanky dps that has armor penetration, the item just flat out fails because you didnt give any substancial dmg from the thronmail to keep you alive and you wasted a lot of golf to purchase it. Think it over. Another item sugestion you make: get madreds to get rid of tanks. Wrong. If the enemy tank has solid magic resist, the bonus you will get from Madreds is almost null. For instance, a Udyr built for tank will take around 1,7% total health as dmg from the Madreds. Great item to get rid of high HP chars? Yes. But as long as they dont stack Magic resist. If thats the case your better off with Cleaver and other penetration items.

Also, in my opinion there is only one way to play Nocturne. As a jungler. But thats my opinion.

Moving one. In your first build, you chose MPen runes. Fail, since you only deal AP dmg from your E. Waste of a good Armor Penetration rune. And forget about Dodge, MR or Armor. Youre an assassin. A pure ganker. Go for Attack Speed and Armor Penetration, flat on. All rest is waste.

Another thing, you miss an absolutely amazing item for almost any dps assassin: Phantom Dancer. It gives Crit, Mov speed and Attack Speed, everythingyou need to be an even more pesky chaser/ganker.

I'd think it through again, if I was you. Because I bet I would easily rape you playing 1 vs 1 with you using this build.
