I removed the references to Cupids - as they are angels and there is no indication that they don't use a host.
Also while the Acheri are called demons in the episode, they are actually a type of ghost, but you can reinsert the reference to them if you like.
Also, I couldn't find where an Enochian chant is used to banish an angel - do you have a reference?
