Arctic weather

A burst of wind and cold rain explodes in a 25 feet sphere within range. Each creature in that area must make a Consitution saving throw. On a failed save, a creature takes 2D10 cold damage and is stuck by the cold for 1 minute, until it can exit the sphere or another creature within reach pull him out of the sphere. A creature stuck has its speed reduced to 5 feet and vision reduced to 10 feet. On a successful save, a creature takes half as much damage and isn’t stuck by the cold.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, increase the cold damage by 1d10 for each slot level above 2nd.
