Withering Ray

You fire a small ray of inky darkness at a target within 200 feet of you. Roll to Hit, on a Hit, the target take 12d8 Necrotic damage and must subtract 2d4 from any rolls they make for the next 10 minutes. On a miss, the ray deals half damage and the target isn't Withered. If the target is reduced to 0 hit points by this spell, they turn into a skeleton that is friendly to you and your allies and disappears after 1 hour, or if it is reduced to 0 hit points. The skeleton known all languages you know and is proficient with all weapons, it has an AC of 12 (that can be increased if you give it armor), has a proficiency of 4, its maximum hit points are the same as yours, and its walking speed is 30 feet. When it dies, all items it had drop on the floor where it stood prior to its disappearance.
