Udyr is one of the best junglers in the game and early game you should focus on leveling up quickly to give your team a significant XP advantage.
Turtle Stance and Bear Stance provides enhanced movement speed and healing. You can use this to dive an enemy champion or escape a gank if you're farming in the jungle.
Very few champs can keep pace with Udyr. Once your on an enemy, they have very little chance to get away. At a certain skill level, most players will realize this and will turn to fight to the death. Make sure you can win before you chase them down.
LoL Udyr players will likely find him to be a difficult champ to build out properly. You'll notice that his build is modified when he is playing against either diversified or highly focused team comps, demonstrating you should not take the same Udyr build every round of League of Legends
The most critical items to include in your champ's build are: The Unspoken Parasite, Frozen Heart, and Demonic Embrace. Those who included these pieces in their kits had a higher winrate than those who tried for other Udyr builds. Similarly, if you are playing a well-mixed enemy team comp, you should really consider grabbing Udyr the Precision, and Inspiration runes. In recent games, he won the greatest number of his matches when using these runes.
