Descending Moon

You create a small illusory moon at a point of your choosing within range, which illuminates a sphere of 15-foot radius around it with bright silvery moonlight. The illusory moon and its illuminated radius are visible to any creature within 60 ft of the illusory moon.

Any creature entering the radius for the first time or starting their turn in the radius must make an intelligence saving throw. On a failure, they take 3d4 radiant damage and are Blinded for the next turn even if they move out of the illuminated radius. On a success, they take half as much damage.

On subsequent turns, you can move the sphere up to 30 ft in any direction.

At Higher Levels. When you cast this spell using a higher spell slot, the damage increases by 1d4 and the Blindness duration increases by 1 turn for every slot level above 1st.
