Eldritch Rain

Casting a spell in the air, the air turns a light blue as the creatures within the targeted range see the impending hail of raining Eldritch Blasts. Each creature within the targeted area must make a dexterity saving throw or take 10d8 force damage and are knocked back 20 feet from their original starting position and prone as Eldritch Blasts are rained down on them. On a failed save, the creature takes half of the damage.

The area affected by the spell is considered difficult terrain, and any creature who starts their turn there, travels over it, or ends their turn on it takes 1d10 force damage.
