Prerequisite: Able to cast one spell with the [cold] descriptor
Benefit: Add +2 to the Difficulty Class for all saving throws against spells you cast with the [cold] descriptor. This bonus is considered to be a Spell Focus bonus, and thus does not stack with any additional Difficulty Class increases you receive from the Spell Focus feat.
