A huge chunk of ice appears in the sky before crashing down at a point within range before shattering into an explosion of ice. Creatures within 30 feet of the point must make a Dexterity saving throw. On failure, a creature takes 6d6 cold damage, and if it was within 10 feet of the target point, it takes an additional 6d8 bludgeoning damage. On success, a creature takes half as much cold damage, and half as much bludgeoning damage (if applicable).   The spell’s area of effect becomes difficult terrain until the end of your next turn.
