Celestial Lances

Enormous lances of radiance plummet to the ground at four different points you can see within range and then disappear. Each creature in a 20-foot-radius, 100-foot-high cylinder centered on each point must make a Dexterity saving throw. A creature takes 12d8 radiant damage and is blinded for 1 minute on a failed save, or half as much damage and isn't blinded on a successful one. A creature in the area of more than one lance is affected only once.
