[Alienfreak]

beast). Once per day, a ring of the beast

can be activated as a standard action to unleash the primal
spirit hidden inside even the most peaceful creatures. When
the ring is activated, [...] As long as the effects of
this ring are active, the wearer also
gains a +2 enhancement bonus to his
natural armor bonus.

But its not stated how long the ring is active after activation? Endlessly if wanted to?
