Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This guide is made to get udyr optimal damage and stand up to other champions instead of people complaining that he doesn't enough. Never enter battle as Udyr without at least cleanse, because we all know he's not a caster, using ghost is a great idea to chase and gank early game(be careful)or also to escape in combination with bear stance and only use cleanse if snared,stun Ect. Remember not to be afraid to turret hug use bear to stun them to get hit by the turret when they're close, and upgrade turtle as you go so that you can lifesteal from minions. Never go in alone with Udyr, cleanse will NOT always save you. Killing neutral creeps for buffs is an awesome way to farm gold/EXP, and what the heck you get a freakin buff. When you clear a lane and you know where everyone is at it's the BEST time to push a lane and WRECK the **** out their turret.... Use your Rune Build the way you want, I suggest health quints and the rest is up to you, even though I did not set a Rune Build.
I HOPE YOU <3 UDYR AS MUCH AS ME. GL HF
