Circle of Frost

Reaching out into the world around you, you draw in all heat from your surroundings, causing patterns of frost to appear on every surface. Every creature within 10 feet of you must make a Strength saving throw. On a failure, each creature takes 2d6 Cold damage and has their movement speed reduced by half until the end of your next turn. On a success, creatures take only half damage and have no movement penalties.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
