Air Barrier

Feats

The shaman creates an invisible shell of air that grants her a +4 armor bonus to AC. At 7th level and every 4 levels thereafter, this bonus increases by 2. At 13th level, this barrier causes incoming arrows, rays, and other ranged attacks requiring an attack roll against her to suffer a 50% miss chance. The shaman can use this barrier for 1 hour per day per shaman level.
