Using a pre-generated character — Maximilian Hirst, parapsychologist — I have a ghost hunting kit consisting of a thermometer, string, screwdriver, and bible. Neither the GM (nor I) could come up with a reason or method of use for the string and screwdriver. Is it a plumb line thing? Some kind of ley line detection?
This pre-generated character is included in Doors to Darkness: Five Scenarios for Beginning Keepers (p. 135). The "gost [sic] hunting kit" is listed under his Equipment as including "talcum powder, thermometer, string, screw driver, Holy Bible".
