Ice Armor

You can conjure armor of ice that grants you a +4 armor bonus. At 7th level, and every four levels thereafter, this bonus increases by +2. At 13th level, this armor grants you DR 5/piercing. In cold conditions, the armor bonus (and DR bonus) increases by 2; in very hot conditions it decreases by 2. You can use this armor for 1 hour per day per oracle level. This duration does not need to be consecutive, but it must be spent in 1-hour increments.
