Lure of the Heavens (Su)

The shaman’s connection to the skies above is so strong that her feet barely touch the ground. At 1st level, she no longer leaves tracks. At 5th level, she can hover up to 6 inches above the ground or liquid surfaces. At 10th level, the shaman gains the ability to cast fly (as per the spell) for a number of minutes per day equal to her shaman level. The duration does not need to be consecutive, but it must be spent in 1-minute increments.
