Cause Hypothermia

You afflict creatures in a 10-foot-radius sphere centered on a point within range with deadly cold. Each creature in the area must succeed on a Constitution saving throw or become Incapacitated and suffer a −5 penalty to all ability checks and attack rolls for the duration as they are wracked with intense, uncoordinated cold. A creature repeats the saving throw at the end of each of its turns, ending the effect on itself on a success.

The spell can affect a total of 12 Hit Points worth of creatures. Creatures with the most Hit Points are affected last.
