Asher's Combustive Blast

A blast of super condensed fire streaks toward a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d12 fire damage.

The spell creates more than one blast when you reach higher levels: two blasts at 7th level, three blasts at 14th level, and four blasts at 20th level. You can direct the blasts at the same target or at different ones. Make a separate attack roll for each blasts.
