Thank you for the kind words :)
I've never tried flat attack damage runes with Noc, his Q does have a decent scaling coefficient (.75) however keep in mind that armor penetration will grant him penetration for Q as well (Q is affected by armor).
I've been working on a talon build using flat attack damage runes, since each one of his blades that lands a hit gets its own individual attack damage bonus, so it essentialy multiplies your bonus AD.

For the second one, It's just a machine. A mad running machine who kills everything in it's part. I understand that nocturne is a good initiator so he needs to be tanky and has to have an heavy damage output.

Oh yeah and remarkable build.

Some people post things with out reading you got to forgive them for that. If i am going to jungle Nocturne I will jungle passively. So which mean i will use runes and masteries. For runes I will going for.

Mark - Attack speed or Attack damage
Seals - Armor
Glyph - Attack speed or Magic resistance
Quintessence - Attack damage or attack speed.

I completely agree with the armor penetration but I like the way nocturne's Q deals Physical damage. On items I don't disagree with your items choice because it's all up to me with the items.

You keep the wriggles until you have mercury treads, and brutalizer + 200g since wriggles sells for roughly 1120. You can do the math and find the exact amount of gold you need to get to, but essentially you're trading the Wriggles for an EARLY Youmuu's. Basically it's worth having wriggles for a few levels instead of foregoing it because it will let you take dragon early, it gives your team vision, and it might lead to a gank. It really only takes you 200g out of your way than if you were go straight for youmuu's and the utility wriggles grants you for the short time you have it is well worth the 200g.

Once you've taken dragon once, there's really no reason to keep it other than the fact that you can keep putting down free wards, but I'd rather have early youmuu's than a few more free wards. You really don't need wriggles to kill dragon mid to late game. With a youmuu's you shouldn't have any trouble killing dragon at lvl 12 (which is what level you should be before it respawns).

Of course if you're doing really well, and have 5+ kills, then you don't NEED to sell the wriggles, but wriggles usefulness falls as the game goes on, so why keep it? Having it for 5 levels or so will let you take first dragon, put down a few wards for your team. It slows down your build to youmuu's a little but if you get a gank because of it, it more than pays for itself. Hell, it pays for itself in 9 minutes anyway if you're putting down wards.

I wouldn't call it late game, since the transition from wriggles happens around level 10-12 (in my experience). That would be mid game. If you're getting ganks (as you should be) you should enter late game with Mercs, Youmuu's, and a blood thirster, or minimum, mercs, youmuu's and a bf sword.

Per your recommendation, I'll split the AD carry and bruiser into 2 builds. If you're going bruiser, you should get merc -> youmuu's -> BT -> Banshee's -> Atma's and then warmogs.

If you're going AD carry, forego the banshee's and atmas for a phantom dancer and another blood thirster, possibly finishing with a banshee's.

Thanks for your input. :)

Getting Wriggle's Lantern, only to sell it almost instantly, is the worst idea I've ever seen in a guide. Wriggle's gives you superb Dragon and later Baron control, as well as some life steal, damage and armor. So there's absolutely no reason to get rid of it, especially so quickly. To be honest, if you plan on selling it in order to get Ghostblade than might as well not buy it at all, as it really won't give you anything other than perhaps the first dragon and a couple of wards.

So, if I understood your guide correctly, you enter the late game with just Ghostblade and Boots(after selling Wriggle's)? that's either a very early late game(mid game by any practical measure) or for some reason you're making way too little gold. The build you posted in your guide is only for the AD Carry, you didn't include a 2nd build for bruiser. By the way, that build is very messy. So, from what I can understand the AD Carry build has Youmuu's, 2 Bloodthirsters, Phantom Dancer, Banshee's Veil and Atma's(7 items total), so I assume you sell Merc Treads for Atma's or something, or is the Atma's part of the bruiser?

So, assuming I understood your build correctly, your build has 2 major flaws. The first is that Nocturne is melee, not ranged, so you can't afford to build all out offense with only Banshee's Veil to protect you from the entire enemy team. The moment you jump in with your ult the enemy team will focus fire on you and burst you down in seconds. The second flaw is that your build basically has 7 big items, and it starts with a Wriggle's that you sell later. There's no way in hell you'll be able to finish such a build, not anywhere close. The only way for you to get near finishing it is if you're getting ridiculously fed(and by ridiculous I mean in the ballpark of over 20 kills and 5-10 assists) as well as 200+ CS. And even than, you'd probably not be able to finish the entire build, just get very close(and we're talking northwards of a 50 minute match too). In your average match you'll barely finish half of the build.

Now, from what I gather your bruiser variant is Ghostblade, Bloodthirster, Banshee's and Atmog's. Sorry but I fail to see how this build is a bruiser, seeing that by the time you actually get to buy Atma's Impaler your average match will be nearly(if not completely) over. So for all practical purposes, even your bruiser build is very squishy until the very end in which it starts getting a bit tanky(which is what your standard AD carry generally does). As a melee champion, rather than ranged, you can't afford to delay your defensive items so much. You don't have the range nor CC/mobility(Ashe's Frost Arrow, Tristana's Rocket Jump, Corki's Valkyrie, etc) to keep the enemy away from you, nor do you want to, being melee and all. So the moment you enter melee(after your ult for example) you'll immediately get focused on and burst down in seconds.

Overall, your guide is very messy, the build itself is following a flawed philosophy(squishy melee) and you're somewhat lacking on the explanatory side.

I've played around with it before, I much prefer a blood thirster to the black cleaver, especially paired with youmuu's and later a phantom dancer. I think for the cost the BT is just better. As for black cleaver vs last whisper, in just about any situation i can think of, other than killing towers, the black cleaver is better. The -45 armor debuff you put on your target benefits your entire team in a team fight, plus the attack speed and damage the BC give you over the last whisper makes it superior to last whisper on all but the absolute tankiest of targets.

If you're already running a blood thirster an a youmuu's, your issue late game isn't really going to be damage output. It's going to be survivability, as teams are going to focus you. I've found Atma's late game to be pretty helpful for surviving teamfights.

... black cleaver isn't that good agaisnt a team that is heavily stacking armor. U should consider it agaisnt every team since last whisper is better agaisnt heavily armormed teams. black cleaver is a great item to deal true dmg to squishies.

Read the item's section of the guide plz. You pick up Atma's if you're intending to play a bruiser and need more suvivability. The black cleaver is good, but it's situational to a team who's heavily stacking armor. Even then, you should be popping squishies, not tanks. Blood thirster is going to be better for killing towers and popping squishies, you get your attack speed from the youmuu's anyway, if you need more grab a zeal/phantom.

I like the item build but I would get rid of Atma's Impaler for the reason that he dosen't have a lot of health, I would put in something else like The Black Cleaver.
