You have mastered the mighty powers of the great mountains that pierce the sky and stand aloof above the lowlands.
Foothold (Su): As a standard action, you can cause an adjacent stone surface up to 10 feet square to mold itself into ridges and creases. A foothold that is created on a horizontal surface is treated as difficult terrain, and a Medium or smaller creature standing in the area or moving through it takes a –2 penalty on Acrobatics checks and to CMD due to poor footing. A foothold that is created on a vertical surface grants a +10 bonus on Climb checks to climb it. The stone remains altered for 1 hour. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
Thin Air (Su): At 8th level, as a free action, you can surround yourself with a 5-foot aura of supernaturally thin air that draws the breath from creatures adjacent to you. Creatures beginning their turn in the aura are fatigued (Fortitude negates). A fatigued creature that begins its turn in the aura must save or suffer from altitude sickness, taking 1 point of ability damage to all ability scores. At 16th level, the aura increases to 10 feet. Creatures that do not breathe are immune to this aura. You can use this ability for a number of rounds per day equal to your druid level; the rounds need not be consecutive.
