Cone of Chill

You unleash a blast of cool air. The temperature of the air and any objects within a 30-foot Cone originating from you drops to 40-degrees Fahrenheit.  If the room is smaller than 30-feet by 30-feet, then the entire room and its contents are chilled, similar to a walk in cooler. 

All creatures within the area must make a constitution saving throw or they get the shivers and are overcome by the urge to wrap up in a cloak, blanket, coat, or otherwise immediately warm themselves; and either a) get disadvantage on their next roll, or b) the next action roll directed against them gains advantage.

Can also be used on bodies of water or another liquid no larger than 200-cubic meters (~1,200-barrels) to instantly cool them.
