The Watchful
This Pathfinder Roleplaying Game supplement explores spirits who remain tied to the Material Plane to protect people, places, organizations, or spiritual successors connected to their former lives. It introduces seven afterlife-themed archetypes for barbarians, druids, investigators, monks, skalds, and swashbucklers, along with a new emotional focus for spiritualist phantoms. These options grant characters ancestral aid, ghostly powers, spiritual guidance, supernatural investigative abilities, and other features tied to guardianship and the afterlife.
