Hello, guys. First of all, I'm not a pro player, not even close and I'v bought Udyr only recently. :) When I looked through the Udyr guides and builds I didn't find the ones that'll suit me, that's why I made this build (just before my very first game with Udyr). It works pretty well for me, so maybe you'll found this one useful too. If you like it, please vote and comment, thanks. :)

P.S.
I'm not a native speaker, so forgive me if I made any mistakes.

The mystics of Ionia delve into the deepest mysteries of Valoran, pioneering the most inner depths of spirituality. Their adepts are some of the most devout proponents of enlightenment and harmony...but as is always the case, there are those who follow a very different path. Born in a grassy clearing under a red moon, Udyr has always been compelled by the primal drive within him. His will was not untempered, simply undomesticated. As a boy, he toiled on his father's farm, but he felt a much deeper connection with the mustangs that would graze in the distant fields than with the townsfolk who would visit. Oftentimes he was dragged into the house at night with a swat and a scolding when his parents would find him sleeping beneath the stars.

On the day of his sixteenth birthday, Udyr bade his family farewell and struck a path to the east, determined to shed the trappings of ''civilized'' society. Freed of the shackles of cultural expectations, Udyr tapped into a well of inner ferocity he hadn't known before. His feral senses roiled to the surface and he let them overcome him. It was at this point in his life that Udyr truly lost his humanity. Poachers and travelers who entered his territory did so at terrible risk, and rarely managed to leave it.

A monk on a long journey passed through his woods one day, and Udyr decided to scare him, leaping from a nearby brush. The monk casually turned and redirected Udyr to one side. Udyr, enraged, tried time and time again to best him, but the monk was unassailable. When Udyr was exhausted, the monk wordlessly beckoned him to follow, and together they walked in silence to the Hirana Monastery. The monks there took him in, and taught him to harness and control his animalistic fury...most of the time.

I don't think that there are better spells for Udyr than and . Smite is a must for jungling (and Udyr's only way to lvl up early game is jungling, he really have no other choice) and Ghost is a must for ganking (Ghost and will surely make your ganks fast and deadly) and actually for jungling too (you'll be jungling faster with Ghost).

The main point of this build is to have crazy Life Steal. But it would be useless without backing it up. And that's why we need Armor Penetration runes Greater Quintessence of DesolationGreater Mark of Desolation(for better jungling and ganking), Magis Resistance runes (to be less vulnerable to the skills that deal magic damage) and Evasion runes (Evasion runes + + Udyr's passive + Evasion and Nimbleness masteries = almost unhittable Udyr :)).

Of course you can use some other runes. I think that Armor runes, Health runes, AD runes and Attack Speed runes are good choice too. But I don't use them. :)

As you can see, masteries are mostly backing up spells, runes and items, so there's not much to talk about. But there is a one thing that I want to say about the Utility mastery. I just don't think that Udyr needs it, because he is not really depends on Blue Buff as much as Warwick for example. Udyr's cooldowns are fast even without any items and he needs mana regen only early game.

Don't get me wrong, I'm not saying that Udyr doesn't need Blue Buff at all, he needs it. All that I wanted to say - the Utility mastery is not necessary.

So. - I highly recommend this order of skills early game. But after learning the Bear Stance you actually have a lot of choices, I can't even say which order of skills is optimal. Everything depends on the situation you are in. Just use you brain. xD

As I've already said in Runes Chapter, the main point of this build is to have an insane Life Steal, so most of the items are for that. But not only for that.

So, I tried to make the item build:
a) Offensive
b) Defensive
c) Not expensive
d) Yeah, vampiristic

If you feel that you need more HP. But your Magic Resistance will be quite low.

It's a nice choice. MR + Spell Shield can really save your butt.

Lots of armor + MR will make you a little more tanky. Revive rarely can save you, but it's still quite useful.

I'll work more on that chapter later. =/

But I guess you should know some things:
a) Udyr is freaking useless in lane (and those guys, who wrote lane guides for Udyr... they just must be kidding)so... go JUNGLE. And then gank.
b) When jungling, kill the Golem first. xD
c) Don't be afraid to use Ghost spell when jungling, it helps (just don't forget that Ghost affects only your movement speed, not attack speed).
d) For a safe jungling use . Set it at the important places - near the Golem, Baron, etc.

First thing to know about a teamfights (at least with this build) - DO. NOT. EVER. INITIATE. THEM. You'll be focused and killed. It's not a tank build, ok?

Just wait untill someone tankish in your team attacks first. The most important thing here is to choose the time right. Don't rush early and don't wait too long (or your team'll be killed xD). If you see that the time has come to unleash your power, choose the Bear stance and rush to the enemy team. Try to stun as many enemies as you can first, then quickly change the Bear stance to the Tiger stance. If they start focusing attack on you, use Turtle stance, restore some HP, then Bear, then Tiger. If the enemy is running, use the Bear stance and go for them (and it's nice if your Ghost spell is ready before the teamfight; if it's ready - use it to catch enemy); when you've stunned the enemy, change to the Tiger stance and finish him off.

If things are looking bad for you, use Ghost + Bear stance to run away.

You can start ganking the enemy team as soon as you have the Bear stance (on 5-7 lvl). Start with the Bear, then change to the Tiger stance and so on. Don't forget about the Ghost spell if the enemy is moving too fast.

Before starting a gank, ensure that the enemy champion is alone (or maybe it's two of them but with low HP). Always pay attention to the minimap to be safe.

Pros:

- Nice physical damage
- Strong Life Steal (it's always cool to have full HP after killing a Baron solo xD)
- Not a tank build, but you'll still have a good defense
- Awesome ganker (if played right)
- Towerdiver/Towerkiller
- Good pusher
- High chance to dodge attacks
- Fast chaser

Cons:

(cons depends on the items you choose, look at the Situational Items chapter)

- He can be squishy
- Vulnerable to CC
- Not a laner at all
- Easily killed when focused
