Touch of Frost

Your touch becomes deathly cold freezing anything is touches.

When this spell is used you make an unarmed spell attack dealing an extra 1d6 cold damage (using charisma as your attack modifier). On a successful hit the creatures movement speed is slowed by 10 ft for one turn. Alternatively you can freeze your currently held (metallic) weapon so that it deals an extra 1d4 cold damage until the end of your next turn.

This spell's damage increases by 1d6/4 when you reach 5th level (2d6/4), 11th level (3d6/4), and 17th level (4d6/4).

This spell may also be used to freeze (or cool) items by touching them. Touching a body of water or a liquid that is principally water (not including water-based creatures), it freezes the liquid to a depth of 6 inches over an area 20 feet square. This ice lasts for 1 minute. Creatures that were swimming on the surface of frozen water are trapped in the ice. A trapped creature can use an action to make a Strength check against your spell save DC to break free.
