Hex
A shaman learns a number of magical tricks, called hexes, which grant her powers or weaken her foes. At 2nd level, a shaman learns one hex. At 4th, 8th, 10th, 12th, 16th, 18th, and 20th levels, the shaman learns a new hex. A shaman can select from any of the following hexes or from any of the hexes listed in the description of her chosen spirit. Unless otherwise noted, a shaman cannot select a hex more than once.
Using a hex is a standard action that doesn’t provoke an attack of opportunity unless otherwise noted. The saving throw DC to resist a hex is equal to 10 + 1/2 the shaman’s level + the shaman’s Wisdom modifier.
