Black Arrow

You touch a quiver containing arrows or bolts. When a target is hit by a ranged weapon attack using a piece of ammunition drawn from the quiver, the target takes an extra 1d6 necrotic damage. A Humanoid creature killed by one of these arrows rises 1d4 rounds later as a skeleton.  The skeleton is friendly towards you and will obey your spoken commands. You may only have a number of skeletons under your command using this spell equal to your Charisma modifier (minimum 1). Trying to create any more than this causes the oldest skeleton to crumble to dust. The spell’s magic ends on the piece of ammunition when it hits or misses, and the spell ends when twelve pieces of ammunition have been drawn from the quiver. The skeletons created by this spell crumble to dust after 1 hour.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the number of pieces of ammunition you can affect with this spell increases by two for each slot level above 4th.
