A burst of freezing wind sweeps out from you. Each creature in a 10-foot radius originating from you must make a Constitution saving throw. On a failed save, a creature takes 2d8 cold damage and their movement speed is reduced by 10ft untill the end of their next turn. On a successful save, the creature takes half as much damage and isn't slowed.

In addition, any water that is not in a container is instantly frozen.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
