This is the first in a series of short blog posts detailing Weird Science Gadgets from Pulp Cthulhu (p.86ff, Pulp Cthulhu rulebook). Each of these posts will include a PDF for you to download and print.
The Mind Control Helmet looks like a traditional pith helmet covered in a web of thick tubes. When worn over the head, it allows the user to attempt to control the actions of another individual. This device functions in an identical fashion to the Dominate spell (p.254, Keeper Rulebook) including range (10 yards), opposed POW roll, magic point and SAN point cost. Stepping inside the mind of another is an unnerving experience.
To build: parts cost $1000, requires 1d10+5 weeks, and a successful combined Hard Electrical Repair and Science (Physics) roll.
