The Portable Neural Pacifier is currently only used for one quest. I propose that, with the advent of companions in Underrail through Heavy Metal, it be an item that can be used to create companion creatures. So just like in the quest you would have to get ahold of the creature you want as a companion and implant it, thus making them docile to you and aid you in combat until they die or perhaps until the Portable Neural Pacifier gives out.
