I'm not even ranked and will probably be disliked for making such an atrocity out of Udyr. But I see that I made Udyr into a more destructive force. This is a fairly new build I'm still working on. If you find this build appealing I will try to keep it updated. :P

In Early Game, due to Udyr's lack of defense and sustain, he is very squishy. You want to play passively and try to get your jungler to gank multiple times in order to get those assists/Kills. Do not over-extend your lane, you're going to want to last hit minions. It's all about that early game advancement, try not to engage your opponent until you hit level 3 and even then it will be tough, and you will most likely end up dying. So try to back to base to get some better items before your opponent does.
