Angel Blades are weapons carried by most angels. They can be used to kill angels, Nephilim, hellhounds, demons, reapers, and possibly other supernatural creatures. This weapon is considerably powerful as it is one of the few weapons that can kill angels and reapers, making them one of the most powerful weapons in existence.
