This spell brings into being a straight beam that moves away from the caster's chest (in the direction the caster is facing) to a distance of 20 feet. The first creature to come into contact with the beam suffers 2d4+2 points of cold damage, and must make a successful saving throw vs. spell or be chilled and shuddering for the rest of the round (attacks not yet taken in the round are lost). Additional creatures struck by the beam suffer 1d4 points of cold damage (half if they successfully save vs. spell).
The material component is a group of three drops of water (or fragments of ice) held in the priest's cupped palm and breathed upon.
Notes: Granted by Auril Frostmaiden of the Forgotten Realms setting. This spell is found only in a few exceptionally rare tomes.
