Udyr uses the stance mechanic. His abilities all have a persistent effect which remain until he activates another ability. Each ability also has a temporary activation effect that occurs upon being cast; the temporary effect of each stance persists for its full duration even if Udyr switches stance. Switching stances sets off a 1.5 second global cooldown.
Monkey's Agility
Each time Udyr switches stances, he gains 5 movement speed and 10% attack speed for 5 seconds. This effect can stack up to 3 times.

Notes
Tiger Stance'sDoT-effect can be procced for the duration of the AS-bonus buff while in other stances.
Tiger Stance'sDoT does not stack; applying another DoT will just refresh the duration.
Udyr cannot max all of his skills. Each skill maxes at 5 ranks, however Udyr will only obtain 18 skill points in total. This means that Udyr may max three abilities (with the fourth only reaching its 3rd rank) or he may max two abilities (with the other two reaching their 4th rank).
While Udyr is blinded, the Tiger StanceDoT will not activate. He can still stun with Bear Stance while blinded, but the hit will do no damage.
