Animal's Attribute

Your touch imbues a willing target with a portion of a bull's strength, a cat's grace, a bear's endurance, an owl's wisdom, a fox's cunning, or an eagle's splendor.  Choose Strength, Dexterity, Constitution, Wisdom, Intelligence or Charisma.  For the duration of this spell, the target's ability score becomes 12 if it wasn't already higher.  If the target's constitution is increased, its current hit points are unaffected by this spell, though its hit point maximum increases for the duration.  If they target has had the chosen attribute temporarily decreased by another effect, the penalty is applied to the score granted by this spell for the duration.  If the target is affected by the Enhance Ability spell, this spell immediately ends.  The chosen ability score granted by this spell increases by 1 at 4th level (13), 8th level (14), 12th level (15), 16th level (16), and 20th level (17).
