You clutch at the air as though grabbing a nearby creature, and then you blow on
your fist. As you do so, ice and snow appear around your foe. A target that fails its
save takes 1d8 points of cold damage per round at the beginning of your turn. Each round,
the subject can make a new Fortitude saving throw to avoid taking damage
that round. The second time a subject takes damage from a single casting of
winter’s embrace, it becomes fatigued. The fourth time it takes damage from
the same spell, it becomes exhausted.
