Void eye

As you call out words of absolute darkness  you summon a giant eye in the sky. You can see every thing the eye sees and you can have it shoot down arrows (for 1d6 damage) at your enemies. As a bonus action you can have the eye shoot down a ray of nothingness at 1 creature the eye can see to heal them for 1d8 and the 2 turns latter they take 1d6 damage.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the healing and damage increases by 1d8 for the healing and 1d6 for the damage for each slot level above 3rd.
