There's more than one way to smite one's enemies.
Using a Higher Level Spell
As alluded to in Part I, the Blasting spell's level can also be increased beyond 1st. Doing so can compound the range, damage, or individuals affected for each level its raised.
For example, making its range 120', targeting 2 individuals in range instead of one, or adding 1d6 to the damage would make Blasting a 2nd level spell. Compounding two of those three options would make it a 3rd level spell.
