You launch a highly compressed ball of fire magic at a creature or object you can see within range. Make a ranged spell attack against the target. On a hit you deal 8d6 fire damage and the target is pushed away from you by 20 feet and knocked prone. Any creatures that were within 5 feet of the target's original position must succeed on a Dexterity saving throw or receive half the damage and be pushed away from that original position by 10 feet and knocked prone.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot level above 4th.
