Hello, my name is Snoop Dogg. I am an ADC and jungle main. I play very few champions in the jungle, but the ones I do, I know them well. I may not be the best mechanically, but I am certainly a stats man.

I've been playing Udyr since before I was even level 30, and been playing him since. Udyr is my go-to jungler for when I need a hard win. He can be built with tank, damage, or both. He's a flexible pick that can adapt to any situation.

My build is designed to show you what I find to be the optimal build for Udyr; Offtank raid boss. With this build, you can initiate fights, dive carries in teamfights, and run through literally anything, and still manage to do a considerable amount of damage. When you play Udyr you need to be Marshawn Lynch. Just run, run, run, baby!

Pros:
-Damage while still being tanky
-Extremely fast
-Good clears and sustain
-Good ganks
-Flexible build path
-Objective control

Cons:
-No gap closer besides pure speed
-EXTREMELY kitable
-Can be a tad underwhelming when set behind
-Falls off late without Devourer

Pick 1:
-Teleport
-Smite

Pick 2:
-Ghost
-Smite

Both of these picks are completely viable. Ghost gives more overall utility, while TP gives map presence. I personally prefer Ghost, but go with what you like.

Starting Items:
Standard start. No need for elaboration.

First Back:
You want Stalker's for the extra chasing/disengage. It's just the best option seeing as hatchet and skirmishers got nerfed, and poachers is still useless. If you can afford a pink on your first back, get that over the green. If you can afford both, that's even better.

Core:
Devourer is a great enchantment because Udyr can farm hard while still having the time and health to gank. It also allows you to infinitely scale into the late game. Trinity force is obvious. Every buff on it scales with Udyr perfectly. Mercs for CC reduction and acclivity for chasing. You can get swifty boots if the enemies don't have a lot of CC or Ninja Tabi if they're all AD.

Offensive Options:
If your team has 2 full tanks such as a Nasus top and a Braum support, then you can trade out a defensive item for an extra offensive item. Blade of the Ruined King is best for damage. It gives a slow, percentage damage, AD and AS, which are all things Udyr loves. You can sell your boots for Zephyr late game if you want. You'll be a bit slower but you will do a lot more damage. Seeing as you will already be extremely fast and have Stalkers Smite, this shouldn't be too big of an issue. Black Cleaver is a pretty decent buy if high priority enemies have a decent amount of armor on them. If the enemy carry buys a Randuins, then Cleaver isn't bad on Udyr. Sword of the Occult for maximum BM and melting.

Defensive Options:
I usually get Frozen Heart, Sunfire Cape, and a Banshees. This can be flexible. If they have a lot of magic damage you might want to substitute Sunfire for a Spirit Visage or a Maw. Zz'Rot is a good mid game split push item and Ohmwrecker is great for diving people under the laser towers. If the enemy team comp has a very even distribution of physical and magic damage, I suggest getting a Randuins, Banshees, and a Guardian Angel.

I start Phoenix, then get Tiger at level 2, then Phoenix again at level 3. If you're starting gromp, take Tiger level 1 and get Phoenix level 2. I usually max Phoenix first for better clear, but you could max Tiger first for better banks, although this is not recommended. If you're ahead you should max Phoenix, then Tiger, then Bear. If behind, max Phoenix, then turtle, then bear and get tanky.

Thanks for reading. Feedback would be appreciated!
