Ash Swish

You hurl a fiery mess at a target within range. Make a ranged spell attack against the target. On a hit the target takes 1d20 fire damage. If you roll a 1-10 on your damage die, you take the damage you rolled. A 11-20 results in a hit and the number you rolled on the die will be dealt to the target. You add your spell attack bonus to the roll. On a miss, roll a d20. If the result is higher than the previous roll, the spell hits.
