Hello I am Zie. I am currently in Silver 3, and quickly climbing my ranks up with Udyr's amazing ganks and clear speed. I play Udyr tanky, with a lot of health, MR, Armor, and utility from my items. He is one of my favorite champs and really my only main jungle currently for ranked. If you want high mobility, being extremely tanky, a fast clear speed, and obliterating your enemy forces just by AA with R, then read on ahead.

Pros
Fast clear speed
Great ganks with proper team work
Super tank
Shape shifting awesomeness

Cons
Can be kited pretty well depending on your skill and the match up
Can have a hard early game if counter jungled
MANA will be your enemy if you do not take a few blues in early game

I follow a traditional Udyr rune page, AD marks, Armor seals, Scaling magic resist glyphs, and MS quints. It gives you the early damage and clear for jungle, and keeps you alive in those click points in team fights later on.

While jungling you want to Phoenix stance. AA 4 times for the second proc, then turtle. Straight back to Phoenix for 4 AAs. Early on you will windle in health a little slow, but later you should never have issues with dragon / mobs.

Usually I try to gank top or mid first, because I always start blue. With blue buff you can prime 3 stacks of his passive for the bonus movement speed. Bear, turtle, then bear. Charging into the lane, ghost if necessary. Bear stun, into an instant phoenix will get a great chunk of damage on the target. If they fight, just stance dance between turtle and phoenix while popping a pot or 2, if they run, follow up with bear for another stun, into a second phoenix proc. Most fights will either end in death on their part, or a flash burnt.

This is my first guide, and Udyr is my favorite champ. He has such a great utility kit that allows him to do so much more beyond imagined. With practice, you will be the star Udyr in your group, so don't freak out from all the friend requests you will get from people wanting to duo ranked with you.

Thanks for reading my guide, I have you enjoy Udyr as much as I do. He will make a jungle out of anyone.
