Thanks for the comments.

As a jungle with his basic kit, he is INCREDIBLY slow. Starts with 300 ms and slow attack speed. Madred's razors only costs another 700 gold, and has a significant impact on jungle speed.

I tried a few games without building this way with mixed success. If you have successful ganks, You can skip madreds. If your ganks fail and you don't have madreds, you can quickly fall behind in XP which makes ganks significantly more difficult.

As for team fights, Until the ~15 minute mark any fights you are in you should have a numbers advantage. Your W scales with Health, so the heal items work well.

I don't always rush warmogs - If graves is getting fed bottom lane I'm going to buy some armor before finishing warmogs. The nice thing about jungling is you can pick who you fight against until mid game, so you dont have to build balanced MR / Armor. You can decided to abuse top and bottom while avoiding the AP carry.

I've not written a guide before, and it's hard to convey how you make decisions on a game by game basis. The item order is a guideline that I deviate as often as not depending on what is going on. I guess that's just part of having an overall understanding of how the game works.

I enjoyed your guide, but dont know if i'd choose to play naut in lane. I prefer to have a support with heals down bottom, a tank in the jungle, with 1 carry in each lane... but I realize team comp is diff from game to game, and from team to team.

Oh and you got my upvote for a different flavor of jungle guide for him. :)

A Warmog's that early is a huge gamble. It's a lot of monetary investment in only health without any resists, so you can end up with a really late Warmogs if you're shut down while building it or directly after and delayed 4-5 minutes in finishing it. Late Warmog's means you have like ~80 armor and a bit less mr when people are finishing infinity edge, 2 dorans, and a zeal on AD carries; and 2xdorans, deathcap and a blasting wand on AP carries. In my opinion, your items aren't bad in an endgame scenario, but they will put you far enough behind to be relatively squishy at the aforementioned ~19-21 minute range where damage dealers typically purchase their first huge increase in damage output.

This is the reason I buy Aegis. Since he has to be with the team basically when teamfights start midgame, he's ALWAYS in teamfights if you play him correctly. Simply having boots1/aegis/HoG before 20 minutes means you can force very favorable teamfights if the enemy team doesn't have an aegis.

I haven't jungled him, so this might be sufficient armor/mr for pressing 2v1 and 3v2 lane advantages early game in surprise ganking situations. I like the idea of a highly mobile ganker early on, I just wonder if buying madred's and boots of mobility first will gimp your durability too much and make your odds of surviving the initiate in the ever-important first teamfight or two much lower.

Anyway, you asked for my comments and that's my honest opinion. I do like your path and your reasoning, but it just might not be my playstyle. Definitely viable, just probably in a different playstyle than I'm used to.

TL;DR: Stay with team to avoid needing boots of mobility, so you can get more mr and cc reduc from merc treads. Build smaller early items that include necessary armor/mr to make him more durable and his shields more efficient (because the damage they absorb is affected by your resistances).

I'd appreciate comments. This is the first time I've written a guide, and this isn't a troll build like all the AP Naut solo mid bullcrap that people are posting. I've used this in a number of games and have found it to be very effective.

I received a -1.. I wouldn't have a problem with this if I knew why.
