A globe of elemental ice appears at an unoccupied point of your choosing, chilling those near it to the bone. The orb has a diameter of 5 feet and hovers.

As a bonus action, you can move the sphere up to 30 ft and then make each creature within 10 feet of the sphere make a Constitution saving throw. On a failed save, the creature takes 5d6 cold damage and has its speed reduced by 20 feet until the end of its next turn. On a successful save, the creature takes half as much damage and is not slowed.

At higher levels. When you cast this spell using a spell slot of 6th level or higher, the cold damage increases by 1d6 for each slot level above 5th.
