jungle nocturn help

Absolutely take him AD. Nocturne's kit involves getting close to the opponent (Q trail, R leap, E radius). Thus, bursting down the opponent is the best thing Nocturne could do. However, I would suggest, along with every other squishy character, giving him at least one sustain item, such as a banshee's veil or a Ninja Tabi, because in late game, assassins are going to go back to base a LOT.

I suggest taking: or Sabre for burst, Stalkers for instant CC for attack speed, and keeping close to the opponent for penetration, CDR, and speed for crit for lifesteal or for tank stats

hope i helped, good luck with nocturne!
