Boreas's Kiss

You cause one target creature within range to become encapsulated in a pocket of fiercely cold air. The target must make a Constitution saving throw or drop any object in hand and suffer disadvantage on any cold-based saving throw each round until they make a successful Constitution saving throw.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher level, you may extend the duration by 1 minute. Alternatively for every two levels above 1st level you may instead choose to have the target also lose a level of Exhaustion on the first failed saving throw, up to a maximum of three levels of Exhaustion.
