As you extend your hands in an arc with thumbs touching and fingers spread, ten small cyclones of chilling frost lance out from your outstretched fingertips. Every creature in a 15-foot cone must make a Dexterity saving throw. Creatures take 3d6 cold damage on failed saves and have their speed reduced by 10 feet until the start of your next turn. On successful saves the creatures take half as much damage and their speed is not reduced.

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.
