Vengeful spirit

You choose and enemy to attack then you outstretch your hand or say (vengeful spirit). The spill forms as a fireball with eyes and flies out and will burn your enemy and knock them back. Enemy takes 1d12 fire damage and is knocked back 10 feet on a failed CON save. When cast at 1st level or higher the spell becomes the shade soul!( double size, change damage type from fire to force, and add 1d10).
