One of my players has recently expressed an interest in a bionic implant that she swears exists but now can't recall it's name nor whether it's actually in one of the DH books or whether she saw it in an different game book altogether and is getting her wires crossed.
She claims there is a bionic eye that is made from a rare and odd mineral that allows it's user to perceive warp currents and warp entities at the cost of their long term sanity. It is an ancient thing which is plucked from one dead wearer and handed off to the next (not unusual in 40k), but I don't remember running across anything like that in any of the books. So, dose such a thing already exist?
If not, I'll come up with the eye my self as it's too cool to pass up. It'll effectively be a condensed psy-tracker made into an eye that will give 1 IP per 9 rolled when using the eyes psyniciance skill or perhaps 1 IP if doubles are rolled. Nice, easy, and simple. I just want to double check that she isn't actually referring to something already stated up and floating in an odd corner of one of the books.
