Blacksky Eye

"Soft eye blessed by a phantasm. They were discovered through Byrgenwerth's contact with the arcane, but in the end, revealed nothing. 
Deep within the eye lies a vast stretch of dark sky that rumbles with an endless meteor storm. The slightest rub of the tiny orb and the rock will tumble and soar."

You create an arrow of blue light and hurl it at a target that is within range. Make a ranged spell attack against the target. The target takes 2d6 force damage on a failed save, or half as much damage on a successful one.

If the target attempts to move out of the 120-foot line, the arrow of blue light has mild tracking within 10ft of the line on both sides.

When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each spell slot over 1st level. Evoking the power of the eye can become especially destructive the more caster uses it. Casting this as a 6th level or higher spell, it gains one extra d6 damage dice for each spell slot over 5th level.
