Poltergeists

Much like vengeful spirits, they are created after a violent death, however, they are almost always invisible and can only affect objects around them. Typically poltergeists possess objects around them to speak to victims. To detect a poltergeist, the best way to find one in a location is to look for supernatural events that can only be created by a ghost. (IE furniture flying or floating, dolls moving, TVs activating at random times.  The best way to protect against a poltergeist is to simply use a cross to ward them off-though some can resist this- or a salt barrier, which acts as it does when dealing with demons, making an uncrossable barrier. If your goal is to kill the poltergeist, then you must either salt and burn the body, though as most poltergeists have been around for many years this might cause an issue, or gather the name of the poltergeist, this acts as a way to easily send them on by placing a sudo “hit” by saying that the materials used to cast the spell are up for grabs if a reaper was to take the soul and move it on.
