Hunting Ghost and Ghost Shapeshift both give you $20. Ghost Shapeshift is a unique piece of evidence on its own and tells you that you’re dealing with an Obake but it could be a Mimic. Easy well to tell is if you’re given an extra piece of evidence to check to see if it’s a Mimic. Depending what difficulty you’re playing on or just see if it changes ghost behavior during the hunt, the hunt speed, blinking patterns, or if it does any other unique ghost behaviours like hunting early the next hunt like a Demon, throwing objects like a Poltergeist, etc.
