You see a blue-skinned old crone with white hair and ancient, immeasurably wise eyes. She wears a white dress and cloak, and leans on a gnarled darkwood staff. Winter and snow seem to follow her wherever she goes.
The cailleach, or winter hag, is doubtlessly the mightiest and wisest hag in existence. It has vast supernatural powers related to winter and the night; therefore it rarely appears by day or in warm seasons. A cailleach hag appears as a blue skinned old woman, with snow-white hair and beady eyes; it also has the ability to appear as an animal, plant or young lass. The creature is always dressed in a white gown and carrying a staff or sceptre; animals such as wolves or ravens often appear at its side.
Winter hags speak Common, Giant, Draconic, Sylvan and Terran.
A cailleach hag prefers to unleash its magical power on opponents rather than entering combat. For this, it relies equally on its winter staff and its innate spell-like abilities.
Children of Winter (Sp): Once per day, a cailleach hag may summon 1 winter wolf, 1d2 brown bears, 1d2 polar bears, 1d6 boars or 1d8 wolves as a standard action. These creatures arrive in 1d4 rounds, after which they loyally follow and fight for the cailleach hag, obeying all of its orders for up to three hours. This ability counts as a 5th level spell.
Spell-Like Abilities: At will–diminish plants, disguise self, gust of wind (DC 17), magic stone, meld into stone, sleet storm; 3/day–blight (DC 20), control water, control weather, polymorph; 1/day–statue. Caster level 14th. Save DCs are Charisma based.
Winter Staff: This Large +2 quarterstaff has all the abilities of a staff of frost, plus it causes a chill touch effect (save DC 11, caster level 11th) on any living creature it successfully touches (including plants).
Skills: A cailleach hag gains a +8 racial bonus on Hide and Survival checks. * When in cold weather areas, the Hide bonus goes up to +12. A cailleach hag gains a +8 racial bonus on Swim checks. It can always take 10 on Swim checks, even if distracted or endangered.
