The Dopamine Harvester, a biomechanical harness, ensnares hosts with barbed tendrils, squeezing while inducing euphoric dopamine surges. It tightens and inflates, balancing torture with forced pleasure.

This sinister device blends horror with psychological torment, making it a uniquely terrifying instrument of dread.
