The shaman causes doubt to creep into the mind of a foe within 30 feet that she can see. The target takes a –2 penalty on one of the following (shaman’s choice): ability checks, AC, attack rolls, saving throws, or skill checks. This hex lasts for a number of rounds equal to 3 + the shaman’s Wisdom modifier. A successful Will saving throw reduces this duration to just 1 round. At 8th level, the penalty changes to –4. This is a mind-affecting effect.
