You raise your arms into the air and call upon an otherworldly entity, causing a barrage of arcane orbs to strike the area around you. Each creature within range, other than you, must succeed on a Dexterity saving throw or take 5d8 force damage and be knocked prone. A creature that succeeds on its saving throw takes half as much damage and isn’t knocked prone.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
