Not Updated For Current Season
Well here are a the Jungle Tank build that I use when i play Udyr.
u are going to get a lot of health and armor, so if u are going against a team whit much ap you can shift some of the item's.
When u jungle after this build you first go after the blue buff, as soon you attack you should activate the first heal potion, when u can u kil the monster whit the smite, and then kill the two small monster's, then you use another heal potion and kill the three wolf's. after that you use another heal potion and go for the ghost's kill them and use the last heal potion and go after red buff, at this time your smite should not be on cd anymore, and you use it to kill him, then the two small mosteres, then you go after the last two monster's and after that you recall and buy what you can(if u got money u sould buy two heal potion or a ward).
Then u just jungle around until you are lvl 5.
When you are lvl 5 u go out to a lane and help whit a gank or hold a lane for the one champion that have been alone at his lane, so he can go back and buy some new item's.
So your three keywords are: Jungle, Gank and Assistance!
Hope that you have as much fun like i have, and good games
