Fear duration, damage taken while stunned, feral forms mana cost
Reduces the duration of fear effects by X%, reduces all damage taken while stunned by X% while in Cat Form.
Primal Tenacity is a talent in the Feral Combat tree, you will need to spend 33 points in Feral Combat to max it. Because it reduces the duration of crowd control abilities, this talent is generally considered a PvP talent.
Patch 3.2.0 (04-Aug-2009): This talent no longer reduces the mana cost of Bear Form, Cat Form, and Dire Bear Form. (This effect has been moved to King of the Jungle)
Hotfix (2009-04-16): "Stunning a druid while not in cat form should no longer remove the Primal Tenacity buff."
Patch 3.1.0 (14-Apr-2009): The damage reduction while stunned effect now only works in Cat Form
