Elden Stone

Stones, dust and earth spontaneously group together into an enormous boulder before your hand which you hurl with magical force towards an opponent. Roll a ranged spell attack against a creature of your choice within range. On a successful hit, the target, and any creatures in a 10-foot-radius sphere around your target who fail a Dexterity saving throw take 4d6 bludgeoning damage.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
