(Spell Compendium, page 241, DnD 3.5)

Evocation[Cold]

Level: ; Druid 2
Components: V, S
Casting Time: 1 standard action
Range: Close (25 ft. + 5 ft./2 levels)
Target: One creature
Duration: 1 round/level
Saving Throw: Fortitude negates
Spell Resistance: Yes

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.
