This is my Udyr Lane Build :D. I focus mostly on dps and beind a tank when your team needs it. Late game you'll be tearing through tanks, supports, ad carries, ap carries, and everything else. So, let's begin.

I like to pick Phoenix first just for the idea of early harassing. I have picked up many kills due to just getting a cc from a teammate and burning through enemies health with the phoenix active. I get the turtle now so I can lane better with the active shields and recovering mana with the minion farming. After this I tend to focus on bear just for the chase asset, Its frustrating to lose a kill when your enemy out runs you. I get a little more turtle for shielding because of annoying laners like Caitlyn. Next is when Tiger comes into play, this is your kill machine. When you get your blood razor your tiger will rip through any squishy. From now on you are a bear tiger man, chasing down and tearing up.

I choose Ghost for its stackablility with Bear and ignite for the finishing touch, you can also go exhaust for those nice ganks.

I go the 21 just for the damage eating capabilities. You'll be tanking almost anything at end game with the items and masteries. They give you the running with ghost, the damage reduction to run or semi tank and the damage to make you op.

this build is flexible if needed. If youre facing a ap type team you can always cut off the Warmogs and purchase a Spirit visage earlier in game. This helps with constant stuns with bear stance and damage with tiger switching. And some of you are saying, what if they just get Thornmail? Dont worry you still have that lucky turtle that will grant you enough lifesteal to survive a thornmail, or you could try your luck and attack him full tiger, with the lifesteal youll outdo the thornmail and keep equal health.

Thanks for reading this is my first guide, try out my build and responses are appreciated :D
