How are techpriest supposed to eat or feed?
I mean, one of their starting implants is the Respirator Unit, whose description states that «the lower half of their face is covered with a network of grilles and tubing»: no mouth then. No teeth, no tongue, no way to swallow (solid) foods.
I know this question may sound silly but it was the hub of our group’s last session: in fact one of my players' new character is a techpriest who joined the other acolytes yesterday.
Of course - like many images show - not every techpriest has a respirator unit implanted but this player says he likes the idea of having one. Therefore I ruled that one of his Electro-Grafts is some kind of recharger: the techpriest plugs in and takes all the power he needs, which is then converted in nourishment.
Yet I’m not satisfied at all by this solution, for much of his body is still flesh and needs more than just raw energy: so I think it’ll be fitter to add a «solid-food plug» to the Respirator Unit or, even better, a pipe on his body he can drip-feed from with special nourishing, high-vitaminized fluids.
Just out of curiosity, did you deal with this matter in your games? Are there bits of information somewhere?
