Accelerate

You concentrate arcane force into a tiny object, accelerating it to immense speeds. Make a ranged spell attack against a target that you can see within range. On a hit, they take 10d8 + 5 piercing damage, and 2d8 + 1 thunder damage.

Regardless of whether the spell hits or not, the recoil is immense. Make a strength saving throw against your own spell save DC. On a failed save, you take 4d6 force damage and are knocked prone. On a successful save you take half damage and don't fall over.

Powerful shockwave. Every creature that is within 5 ft of the path of the projectile, and is not directly damaged by it, takes 1d4 thunder damage. This includes the caster, the target, if the attack missed, and any creatures who succeed on their dexterity saving throw to avoid being caught in the line of fire.

Other creatures in the line of fire. Draw a straight, 50 ft line that begins at the caster's position and passes through the target. this is the trajectory travelled by the projectile. any creature within 5ft of this line must make a dexterity saving throw against the spell save DC of the caster, minus five. On a failed save, the projectile glances off them, dealing 2d8 piercing damage and 1d8 thunder damage. On a successful save, they take only the 1d4 thunder damage from the passing shockwave. After travelling for 50ft, intense aerodynamic heating has evaporated the projectile into plasma, causing it to disintegrate and lose potency.

On inanimate objects. When this spell hits a static object, either as a target or as collateral, it deals its full damage. If the object is brittle, such as glass, quartz, concrete, marble, thin stone, some metals, and all ceramics--  basically anything that can shatter-- the spell always produces a critical hit when striking such objects.
