Unbelievable. You don't buy Trinity Force nor Randuin's Omen which is a core item on Udyr (Trinity gives Udyr very high damage even with tank items, and Randuin's Omen reduces your kiting problem), you don't take the increased buff duration in your masteries, you have absolutely no early game power through your build and masteries (too much unneeded stats), and your title is inappropriate and unprofessional.

It also looks like you crammed the images there randomly in an attempt to make the guide look good, along with huge typing and coding errors with no punctuation when it comes to explaning details.

However your most crucial mistake is that YOU BUILD AD ON PHOENIX UDYR. Your build would have been great if it was a Tiger Udyr build, but not Phoenix. Wingborne Storm scales completely off attack speed and you have almost none of that. That also means that your runes, masteries and items contain too much unnecessary stats that Udyr does not need.

Don't get me wrong, I respect you as a fellow Udyr player, but you really need to know the right things to do on Udyr.

I agree about the Madred's Bloodrazor, but I feel that getting Wriggle's Lantern isn't necessary. Udyr is actually the tankiest character in the game at Level 1, making him extremely durable along with Iron Mantle which will also give him a nice amount of sustain and the shield to block out a lot of damage while getting all of your health back. Therefore, I normally just rush Heart of Gold then go to my Wit's End after boots of course. Also, looking up at earlier comments, you seem to have changed your build around but you haven't changed that in your actual guide in the following places:
Core Items
Masteries

I would also suggest a situational items section since there are so many good items for Udyr. Some items that aren't in your main build that I know are really good on Udyr are Randuin's Omen, Spirit Visage, and Maw of Malmortius, however, those aren't the only items that are good besides what you have. Finally, I would add a counter junglers section so that you know who you can beat as a jungler, such as Amumu as you will most of the time be able to shut him down, and who you will be beaten by (not sure who beats Udyr but I know that Xin Zhao gives him trouble when he tries to gank sometimes, but I am not sure).

I do approve of everything else here though, so adding atleast a little of this at the time right now and I will see that you get a +1.

Also, if you get the time, come check out my Jax guide :)

I promise I will make better builds in the future!

Sorry this build was so bad guys , it was m first one I just wanted to try it out..

Also... Both Warmog's and Mallet is a little overkill on health... Obviously you want the most health for the Atma's, but thats just too much health. I prefer a triforce or a madred's instead of the mallet. However, this is already a VERY expensive build, so it may be cheaper to just put off the triforce.

ALSO, you do magic damage as Udyr, so taking armor pen in the mastery tree is just kinda worthless. I would go 0/21/9 masteries as jungle Udyr for sustain and defense, but that's just me...

There i changed it, i hope it's better now, im always looking for improvements!

Don't replace GA.

What do you recommend I replace GA for?

A wriggles on Udyr is pointless, you have enough sustain, and you don't take much damage. Just buy wards, its cheaper then a Wriggles ultimately.

WIts End + GA does not give you AD. The passive and armor does not give you sustain, rather it makes you tanky yes, but lack a lot of damage.

As for Madreds, I'd highly go against it, but that is just from my ranked experience, as well several high level Udyr players I know personally.

You get the wriggles for mostly warding and the life steal so you dont have to keep switching from Wingborne Storm to Iron Mantle also i rush a GA after wits end because it gives you a little ad and a little sustain with its passive and armor, i agree with you on the t-force, i think the madreds would be enough for ad, so i will change it to frozen mallet for its damage and health, thanks for the tips!

You say it is a ranked jungle guide, but it hardly seems tested. You yourself seems unsure with the items that you need.

1. You don't need a Wriggles on Udyr, your sustain is strong enough. GP10 early game meta builds work well with him much more then making his already fast sustain even faster (unnecessary).

2. You build a fast Wit's End when going a phage first would be much better.

3. I find the rushed GA unncessary as well. You can put it off for later.

4. The Trinity Force seems unneeded, wouldn't a Frozen Mallet be much better? You don't really state why a T-Force would be ideal. A 'bit of everything' isn't good for all champs, and it isn't particularly effective for him either.

5. A Madred's Bloodrazer seems rather pointless on Udyr with your current build. You don't need any more attack speed, nor is the damage necessary in 90%+ games. Hardly something worth being in a regular ranked Udyr guide.

6.You lack a Frozen Heart or Randuin's Omen, two of the strongest items in the game for any bruiser-tanky jungler.

7. Finally, a Warmog by itself it pointless, you should replace it for something better, such as Maw or Banshee's Veil. Or go Atmogs.

8. Other choices to add in are Black Cleaver (attack speed, armor reduction, damage) and Philosopher's Stone and Shruelya's Reverie (GP10, sustain, and powerful active).

All in all, you say ranked, yet your items are so irrational, and you seem to have no confidence over them.

For your mastery tree, getting Indomitable is highly suggested as it reduces a lot of damage throughout the game.

Udyr's skills are unique and require much explanation, especially combo'ing your skills, specifically ganking and in teamfights. You go over very little of it, just the common sense portion. You should really go into detail for the skills.

Your formatting is very closed together, with many grammar mistakes and coding mistakes, and worst of all - there are too many colors. You abuse colors way too often making it unpleasing to the eye.

You state at the end he is hard to use, but go over very little of why he is hard to use, and how to get better at him.

All in all, I'll gladly change it to a +1 if you make the proper changes, but as of now, I'm afraid I'll have to give you a -1.

Great effort and great start!

Well thank you guys for the feedback I changed it, I like the feedback!
