Hydaelyn

You cause a burst of unaspected aether to ravage a 10ft. radius sphere at a location you can see within range. Each creature in the affected area must succeed on a Dexterity saving throw or take 2d10 force damage on a failure, or half as much on a success. When you cast this spell using a spell slot of 2nd level or higher, the damage dealt increases by 1d10 for each slot level above 1st.
