The gravity in a 10-foot-radius sphere centered on a point you can see within range increases for a moment. Each creature in the sphere on the turn when you cast the spell must make a Constitution saving throw. On a failed save, a creature takes 2d8 force damage, and its speed is halved until the end of its next turn. On a successful save, a creature takes half as much damage and suffers no reduction to its speed.
Until the start of your next turn, any object that isn't being worn or carried in the sphere requires a successful Strength check against your spell save DC to pick up or move.
A burst of cold energy emanates from you in a 30-foot cone. Each creature in that area must make a Constitution saving throw. On a failed save, a creature takes 3d8 cold damage and is hindered by ice formations for 1 minute, or until it or another creature within reach of it uses an action to break away the ice. A creature hindered by ice has its speed reduced to 0. On a successful save, a creature takes half as much damage and isn’t hindered by ice.
At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, increase the cold damage by 1d8 for each slot level above 2nd.
