Bullet

You compress magical flames into a miniscule, high power dart of fire. Make a ranged spell attack against a creature you can see within range. On a hit, the target takes 3d10 fire damage.

Furthermore, if the target is within 100 feet, they must succeed on a Strength saving throw or be pushed back 10 feet. If the target is within 200 feet, they must succeed on a Strength saving throw or be pushed back 5 feet.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the distance a creature is pushed back increases by 5 feet at each range increment for every two slot levels above 2nd.
