To learn or cast a spell, a winter witch must have an Intelligence score equal to at least 10 + the spell level. The Difficulty Class for a saving throw against a winter witch’s spell is 10 + the spell level + the winter witch’s Intelligence modifier.
A winter witch can cast only a certain number of spells of each spell level per day. Her base daily spell allotment is given on Table: Winter witch. In addition, she receives bonus spells per day if she has a high Intelligence score (see Table: Ability Modifiers and Bonus Spells).A winter witch may know any number of spells. She must choose and prepare her spells ahead of time by getting 8 hours of sleep and spending 1 hour communing with her familiar. While communing, the winter witch decides which spells to prepare.

When a winter witch casts a spell with the cold descriptor, the save DC of the spell increases by +1. Any spell for the fire subtype that deals fire damage instead gains the cold subtype and deals cold damage for the winter witch. Such spells can never set anything alight. The winter witch cannot learn or cast other spells of the fire subtype.
Unless otherwise noted, using a hex is a standard action that does not provoke an attack of opportunity. The save to resist a hex is equal to 10 + 1/2 the winter witch’s level + the winter witch’s Intelligence modifier.
