This spell improves on the resist nature’s lure class ability of the druid or ranger. Thorns, briars, and overgrown areas that have been magically manipulated to impede motion still affect you, but if such magical effects grant a saving throw, you gain a +4 competence bonus on the appropriate save. In addition, you gain a +5 competence bonus on Stealth checks in areas of medium to dense vegetation (GM’s discretion), and a +5 competence bonus on all Diplomacy checks made to conflict elves, gnomes, plant and fey creatures.
