Not Updated For Current Season
My jungling guide to Nocturne. Basic jungling tactics, I start with cloth armor and 5 pots. I then take blue first with some assistance from mid or whoever answers to my pleas of help. Depending on how much help, I may pop 1st pot. Next wolves, where I normally pop 1st/2nd near the end. Wraiths, then golem for a 2nd or 3rd pot. Make sure you're near all the minions before attackin to take full advantage of his passive. Normally hit level 3 by this point and I'm checkin top to see if he needs help pushing lane back or for a gank. If he's fine and there's (or after helping top) I recall and grab long sword and head back to wolves. This levels us to 4 and I'm looking to get a kill at bottom since I just learned fear. Some people wait for red, but after jungling nocturne since he came out, I find it keeps the enemy in fear and leads to more opportunities for a kill. Recall after gank and grab yourself madred's and maybe boots. After this, jungling is easy, grab red right away and use your best judgement on ganks.
I always grab merc treads, as it is the only logical choice for this champion. There's always CC and this keeps you on your target the best. With optimal use of shroud, you can be pretty aggro. After that I rush BF sword to up that Q dmg and base dmg and then straight for black cleaver. I love this item on Nocturne. Atk speed is great on this guy, esp. with the life steal from wriggle's. And the armor pen added with armorpen runes, makes you a threat to their tanks as well. Always keep placing those wards as well.
By this time, you should have some kills/assists under your belt. After recent testing, I decided to start using the gunblade. It adds more lifesteal, ad, ap, spell vamp, and gives you a ranged slow. These added stats make you tankier from lifesteal and that use is awesome for closing the gap with your Q, and keeping them close for your E. An added benefit is the +75 or so dmg to ur E along with an additional 300 dmg ability. It seems to work very well. I've found myself tankin 2 and sometimes 3 ppl by this point. Absorb a spell with W and pop your E and your life seems to stand still. I add ghostblade for obv. reasons and finish with more lifesteal and ad to add to their humility.
I know this may seem to be a lot of buttons to remember, but if you're not a tunnel vision player, this build will earn it's keep. I'm thinking about adding CDR runes for added dmg and spell vamp with gunblade, but MR runes help against everyone and make Nocturne a litte tankier. This is my first guide I've thrown together, and decided on the lazier route. I may be editting later to give it more substance. Feel free to comment, everyone could use some criticism for improvement.
