instead of warmongs you would be better off using frozen mallet becasue it still gives you alot of hp and it lets u slow the enemies and gives you a little bit of attack damage.

Imo this build doesnt give me anything new...i mean i can play many AD charas like this. Its nothing special (regardless if this build works out or not, for me it doesnt). I agree with Phantom and Bloodthirster but theres no need for an Infinity Edge. Better get something for health (Frozen Mallet) or more AD/AS (Black Cleaver).
And where is your Banshee's Veil anyway? It's the best item for Nocturne (Double Spell shield + Mana + Health)
Then I dont agree with your Seals. Why dodge? Mana Regen is more powerful for him.

Hope you think about my comment =)

warmogs is needed in late game cause u are squishy as hell....

why the dodge runes? some mana regen runes would fit a bit better there i think. ever tryed to swich warmogs for frozen mallet? It would make you a better chaser and still give you a bunch of hp. not as much as warmogs but still good.

Even thou , it has great runes and masterys

Tried it , didnt work out for me :/ i always die even with all the stuff

Very good build. I hate nocturne as a jungler and this build is perfect for laning and team fights later on.
