@AFKDYR Sibitrix I'll reply to each of your things individually

1) I never said that the build was invented by Trick2g. I said it was popularized by Trick2g. Which is true, Trick2g made the popular, he is the reason that it got popular. More people know about Trick2g as the big " Udyr player", and so that's how people discovered the buiild. I did not know who invented the build, but I shall add his name in the next update of the guide.

2) The build is based off of what is popular to build, and what works well. You can buy the Zz'Rot second if you'd like, it's all up to preference.

3) "You max tiger..." I had not played Devourer Udyr since early S5 and did not know things had changed, so I will remove that from the guide.

4)Out of all the things they could nerf, they might nerf the movement speed Enchantment: Runic Echoes gives, or the AP ratio on his Iron Mantle. I get that it's strong, and that everything that is strong gets nerfed, but that is fairly obvious, and I expect it to get nerfed soon.

-The build was NOT made by Trick, it was made by René Emilio, one of the first challengers on EUW from spain. He popularized Zz'Rot Portal as core item, the insane early boots upgrade. The only Thing trick did, was building Iceborn Gauntlet as first Item (a lot of the times before the Jungle Item). The strengh of this build however is to quickly get Zz'Rot Portal because the Item is broken on Udyr (Like Udyr is with this build anyways. Highest Winrate and popularity in every Elo, solocarry potential). Some more things about René Emilio: He was not only one of the first challengers, he had one of the highest winrate on his way there and had the highest LolSkillScore(A site where you get a score with a champion based on Games Played, Elo and Performance) not only with Udyr but of all Champions. Thats why the build got so popular later in patch 5.2, i dont know really how, but suddenly everone played it.
-This is your guide so maybe you did it on purpose but your Core Build definetly the wrong order and you build too much damage, the strengh of the build is (except that its overpowered in every stage of the game, after 1 Item, after 2 Items, after 3 Items and Lategame anyways[Maybe not when everyone is fullbuild]) that you practicly cant die after 2 Items. I dont know how but every Udyr with Zz'Rot Portal does not receive ANY damage at all. And it doesnt matter if he is fed or not.
-Some little errors in the content fE "You max tiger stance second on a normal devourer Udyr", you really never do that, it was a viable option in S4 and early S5 but its not any way to go now. Or "Your shield is quite useful for this build", your shield is the only reason this build is overpowered. You go for full resistences and your 200 shield + your AP with the small Udyr Cooldowns gives you in a longer fight more health then your actual HP. Your shield can block not only the last tick of ignite, it blocks the whole ignite. It blocks a whole Zed ultimate.
-I know your guide isnt finished but you should have talked about the problems of this build.
The winrate(On 6.2 57% in Platinum+, and this will not change in 6.3) is too high, other champions with a that high winrate got hotfixed. Udyr or the items and masteries have to get nerfed. And not only a bit. But it makes no sense to nerf ZzRotPortal.
What will they nerf? The jungle Item is fine, Udyr itself is fine, ZzRot is fine. Its just the combination, but they cant let this exist.

nice guide brudi

Thanks m8 :3

very good Kappa

Skirmisher's Sabre is a good choice as well, I just feel that the added slowing effect of Stalker's Blade is better.

I'm glad to hear you like the guide! It is being constantly updated, as I'm attempting to finish the guide with optional items, early game, mid game, and late game descriptions, and more! Check back soon to see the updates!

Pretty nice guide. I have been trying this build last few games and it is amazing, its just that I use red smite for that true damage.
