Missile
Create a 1 yard sphere of swirling ice and frost that hangs in the air. Once shaped, the frost storm keeps that shape until the spell expires, without concentration. Moving the sphere requires constant concentration (the sphere moves at Move 5, on the caster’s turn). The sphere inflicts cold damage to all within it. Creatures in the sphere take damage on their own turns. If less than an entire second is spent in the affected sphere, damage is halved (round down).

Duration: 10 seconds.
Cost: Any amount up to your Magery level per second, for three seconds. The sphere does 2d cold damage per energy point.
Time to cast: 1 to 3 seconds.
Prerequisites: Ice Sphere, and Shape Air.

Item
Staff, wand, or jewelry. Usable only by mages.
Energy cost to create: 600; must include a sapphire worth $400.
