You conjure four giant lances of radiant energy that plummet down at four different points you can see. Each creature in a 10-foot-radius, 100-foot-high cylinder centered on each point must make a Dexterity saving throw.
On a failed save, a creature takes 8d8 radiant damage and is knocked prone. On a successful save, they take half as much damage and are not knocked prone.
A creature in the area of more than one lance is affected only once.
