A shower of flowers falls across the ground at ten different points you can see within range. The flowers fall in 10-foot cubes centered on each point, and each cube must be contiguous with at least one other cube. Each friendly creature in a cube chooses one of the following when the flowers appear—it regains 10d6 hit points or it is cured of all diseases and all the following conditions: blinded, charmed, deafened, paralyzed, petrified, and poisoned. Each hostile creature in a cube must make a Dexterity saving throw, taking 10d10 necrotic damage on a failed save, or half as much damage on a successful one. A creature in the area of more than one cube of falling flowers is affected only once.
