Thermal Snap

You wave your hand across your chest as the air in front of you shifts, snapping your fingers at the end of the movement. Each creature in a 30-foot cone in front of you must make a Constitution saving throw. On a failed save, each creature in the area of effect takes your choice of 2d8 cold damage or 2d8 fire damage and has disadvantage on ability checks until the start of its next turn. On a successful save, the creature takes half damage with no added affect.

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.
