This spell creates twelve shards of ice. After the casting, the shards start spinning around the caster in tight orbits at tremendous velocity. The shards move with the caster, and will not affect the caster's movement, attacks, or spells. If anyone tries to physically attack the caster, he must make a saving throw at -4 for each shard or be hit by a shard. Each shard hits for 4d10 points of magical cold damage.
