Touch of Frost

You reach out and touch a large or smaller nearby creature or object, turning it to solid ice.  Your target must make a constitution saving throw.  If your target has resistance or immunity to cold damage, it has advantage on the saving throw.  If your target is a non-sentient object, it automatically fails the saving throw.  On a failed saving throw, the target is paralyzed indefinitely.  The target now has an AC of 13 and and 18 hit points.  If the ice is reduced to 0 hit points, the target dies.  There are many things that can end this paralysis.  Such as:  If the target is left in a temerature above 32 degrees farenheit (0 degrees celcius), takes more than 8 fire damage, or is affected by a spell higher than 4th level that ends paralysis.
