@JeremyECrawford can a ghost make a possessed character use its oath from an oathbow or can the ghost use the oath? Please confirm. Thx

A ghost that possesses you doesn't gain your knowledge. For instance, a ghost would probably have no idea how to activate your oathbow. #DnD https://t.co/ShqnnijD0M
