Hypothermia

Feats

The shaman afflicts a creature within 30 feet with hypothermia. The target must attempt a Fortitude saving throw. On a failed save, the target is fatigued for 2 rounds. At 8th and 16th levels, the duration of this hex is extended by 1 round. Whether or not the save is successful, the creature cannot be the target of this hex again for 24 hours.
