Blast

When you cast this spell, a powerful explosion emanates from your hand. This explosion can be used to "blast off" and move 60 ft per use, or be used in combat. The spell has a range of 25 feet and requires the target to make a dexterity saving throw. If the chosen target fails their saving throw, they take 4d8 of fire damage and are knocked back d10 feet. On a successful saving throw, the target takes half the damage (2d8) and is not knocked back. If the target failed their saving throw, after taking 3d10 of damage, it takes a d6 of damage for the next two turns. You can use the spell "Blast" with a level 7 spell slot which does an extra d10 immediate damage, and increases range by to 30 feet.
