Water

As a standard action, you can fire an icicle from your finger, targeting any foe within 30 feet as a ranged touch attack. The icicle deals 1d6 points of cold damage + 1 point for every two cleric levels you possess. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.

At 6th level, you gain resistance to cold 10. This resistance increases to 20 at 12th level. At 20th level, you gain immunity to cold.
