A frigid globe streaks from you to a point of your choice within range, where it explodes in a 60-foot-radius Sphere. Each creature in that area makes a Constitution saving throw, taking 10d6 Cold damage on a failed save or half as much damage on a successful one. If the globe strikes a body of water, it freezes the water to a depth of 6 inches over an area 30 feet square. This ice lasts for 1 minute. Creatures that were swimming on the surface of frozen water are trapped in the ice and have the Restrained condition. You can refrain from firing the globe after completing the spell's casting. If you do so, a globe about the size of a sling bullet, cool to the touch, appears in your hand. At any time, you or a creature you give the globe to can throw the globe (to a range of 40 feet) or hurl it with a sling. It shatters on impact, with the same effect as a normal casting of the spell. After 1 minute, if the globe hasn't already shattered, it explodes. Using a Higher-Level Spell Slot: The damage increases by 1d6 for each spell slot level above 6.
