A winter witch gains endure elements as a constant, spell-like ability, but only against cold temperatures. At 4th level, she gains cold resistance 5, making her comfortable in near-freezing temperatures. This replaces the witch’s 4th-level hex.
At 2nd level, a winter witch can freeze water or melt ice and snow with a touch. As a standard action, a winter witch can melt an adjacent 5-foot cube of ice or 10-foot cube of snow. Melting snow produces a volume of water equal to 10% the snow’s volume. Alternatively, a winter witch can freeze 5 cubic feet of water into solid ice. This freezing takes place gradually over 1 round, making it almost impossible to trap a creature unless it’s helpless. This ability cannot affect water within a creature. One cubic foot of ice contains roughly 8 gallons of water and weighs about 60 pounds. This ability works on fresh water and saltwater, but has no affect on water creatures; on liquids (frozen or otherwise) other than water; or on magical water, ice, or snow. A winter witch can use this ability a number of times per day equal to 1/2 her class level.
A winter witch’s patron reveals an icy aspect. A winter witch adds the following spells to her spell list at the following class levels, but does not automatically learn them: 3rd—wall of ice, 5th—icy prison, 7th—freezing sphere.
When a winter witch casts a spell with the cold descriptor, the save DC of the spell increases by 1. A winter witch cannot learn or cast spells with the fire descriptor.
At 4th level, a winter witch can sculpt ice and snow into any shape that suits her purpose (as stone shape, except that it works with ice). This ability also works on snow, doubling the volume affected. At 7th level, this ability functions on ice or snow like the fabricate spell, increasing the volume manipulated and allowing a higher degree of craftsmanship. The winter witch must succeed at appropriate Craft checks to form complex items or ones with fine detail. Items created by the fabricate version of this ability solidify into ultra-hard ice (hardness 5, 10 hit points per inch of thickness) that resists normal melting but takes double damage from fire. The ice remains in this ultra-hard state for 1 hour per class level before returning to normal ice. A winter witch can use this ability a number of times per day equal to 1/2 her class level.
At 3rd level, whenever a winter witch’s spell, spell-like ability, or supernatural ability deals cold damage, treat affected creatures as having half their normal cold resistance when determining damage dealt.
Levels of the winter witch prestige class stack with witch levels for determining when the winter witch learns new hexes, the effect of her hexes and other witch class abilities (including archetype abilities), the abilities of her witch’s familiar, and the level at which she can select major hexes or grand hexes.
