Several jagged shards of ice are frozen onto this white cord. These ice crystals are still cold and show no evidence of melting.

You can detach and throw one of the ice crystals on this cord as a standard action. Each crystal can be thrown up to 80 feet. When it reaches the end of its trajectory, it explodes to create an ice storm or sleet storm (as the spells) centered on its endpoint.
Each of two opaque crystals creates a sleet storm effect, while each of four transparent crystals creates an ice storm.

Prerequisites: Craft Wondrous Item, ice storm, sleet storm.
Cost to Create: 1,000 gp (plus 500 gp for base item), 80 XP, 2 days.
