The forest consumes the final shreds of twilight, and the derelict laboratory exhales a damp, metallic chill. Particles of ancient dust swirl in the stark beam of your torch as it illuminates a sealed glass case, a tarnished plaque proclaiming: 'Instant Localized Weight Gain Inflictor.' Within rests a sphere, roughly the size of a softball, its surface a constellation of intricate dials, switches, and a single, prominent rubber node. The moment your fingers curl around it, a small, dark screen flickers and glows to life. "Please place rubber contact point to subject's desired area to begin." A low, persistent hum vibrates through the casing into your palm, the artifact poised for your command.
