Hi im ShadowBro in game name BroStylez i have made this guide to help you people who want to differ from the meta of udyr normally people want to go bloodrazor but i believe that this build is as good if not better and i am a level 5 Udyr so i have had a lot of experience with Udyr so i hope this guide can help you dominate and some may say your a troll which happened in one of my games but when you carry them they change there minds fast :)

Pros

+ Good dps + Udyr is a great ganking champion + Damage and tank at the same time :D + Cosplay as animals

Udyr is a great jungle champion in the jungle as his abilities gives you great sustain and gank potential with bear stance this is not a great description of how good udyr is but by playing him you will get the jist .

Pros

+ can get easily kited early game + hard to get to the back line + cant think of more FeelsGoodMan

This item is great for jungle udyr as bloodrazor only provides you with attack speed so with warrior you gain that extra damage early and the 10% cdr which will allow you to output some good damage early game and thought the rest of the game

Youmuu's is a strong starting item on udyr as it gives you even more damage ontop of warrior and the armor pen attack speed to just melt your opponents also the movement speed will help you catch the enemies

I know this looks weird on udyr but it actually does work as it gives you the 1v1 potential with the 12% damage reduction and the attack speed to kill people faster

These are really the key items to this build the rest really just depends on what you come up against if your getting one shot build more tanky so you can get to the back line and kill those squishies else if your dominating and think you can stay alive then just build damage go for like a tri force and stuff like that or like a bloodthirster and a spirit visage for crazy sustain.

This is just a quick answer to why some of you may question the thunderlords choice well to answer that it is a easy thing to proc with tiger stance as your going to be attacking that fast you can proc it easily so your burst damage is increased as the tiger stance dot plus your basic attacks with the thunderlords proc instantly good damage which in a gank could mean a kill for you or the laner.
