5-level Evocation
You conjure a pillar of moonlight to strike your foes with lunar power. Each creature in a 10 foot radius, 40 foot high cylinder of moonlight centred on a point within range must make a Constitution saving throw. On a failed save, a creature takes 3d6 cold damage and 3d6 radiant damage on a failed save and is blinded until the end of its next turn. On a successful save, a creature takes half as much damage and isn't blinded.
Illusions cast using a lower level spell slot than this spell in the spell's area are dispelled.
When you cast this spell using a spell slot of 6th level or higher, the cold damage or the radiant damage (your choice) increases by 1d6 for each level above 5th.
