Snow Dust

Snow Dust is a sparkling-white, crystalline powder, always contained within a black glass vial with a tightly fitted stopper. Dust feels cool to the touch, and if exposed to air or sunlight for more than a few minutes it will slowly sublimate, leaving nothing behind. If examined for magical properties it radiates Superb alteration magic. A Great test of divination magic will reveal its powers.

Snow Dust is activated by tossing a pinch into the air under the open skies. This has the following effects:

• The ambient air temperature drops to sub-freezing temperatures within ten minutes.
• The sky becomes cloudy and overcast, completely obscuring the sun.
• Precipitation immediately turns to snow and increases in intensity. If no precipitation is falling, there is a 25% chance per hour that snow will begin to fall. Snow accumulates at the rate of three inches per hour.
• Open water begins to freeze, accumulating one inch of ice per hour.

The effects of Snow Dust cover a one mile radius area and last for one day. At the end of the period, temperatures return to normal over the course of an hour. Accumulated snow and ice melt at a normal rate.
