Bag of Bones

The holder of this leather bag may reach into it and say one animal name: human, horse, or dog. As a bonus action, they then pull out a full set of bones from the animal they named. The bones clatter to the floor within 5 feet of the user and, on their next turn, animate into a skeletal version of that creature loyal to the user. They have the stats of a skeleton, but only have claw attacks. The skeletal horse may be used as a mount. They last for up to 4 hours, or until they drop to 0 hit points, at which point the bones turn to dust and fly back into the bag. That creature may not be named again until the next dawn. Only one creature may be called from the bag at one time.
