Enhance Quiver

You touch your quiver containing arrows or bolts and Enhance 8 pieces.
When a target is hit by a ranged weapon attack using a piece of ammunition drawn from the quiver, the target takes an extra 1d4 force damage. The spell’s magic ends on the piece of ammunition when it hits or misses, and the spell ends when all 8 pieces of ammunition have been used.

Arrow enhancement lasts until the first long rest or until quiver leaves your possession. 

At Higher Levels. When you cast this spell using a higher spell slot, for each slot level above the base, the number of pieces of ammunition you can affect with this spell increases by 3 and the force damage dice used increases by 1 level.
