Trueshot Barrage

You throw a mote of shimmering gold light into the air and choose a point within range. Hundreds of duplicates of the mote of light fall in a volley from above and then disappear. Each creature in a 40-foot-radius. 20-foot-high cylinder centered on that point must make a Dexterity saving throw. A creature takes 8d8 radiant damage on a failed save, or half as much damage on a successful one.
