Conjure Ice Armor

You control water or ice either on or near you to surround you. Pushing your hands down the water or ice swirls around your feet, you pull your hands up and the still swirling substance begins to crawl upwards leaving some behind on you. Continuing you eventually get it to cover you, and shape it into armor. You freeze it to your form and it solidifies. The armor gives you an additional 12 to your appropriate armor modifiers. The armor will last until you turn it into water, or you are in or near someplace that is warm or hot within 10ft of you.

-vulnerability to cold by 1d4 which is taken from your 12 also taken if your within 10ft from a heat source.

-immunity to cold for 4d4 rounds or if armor is destroyed.
