questions about tech, etc.

giorno can .... frankenstein body parts from inorganic things as seen in his info page. what's the effect on that on tech/augmentations? how much can he do, and what can't he do?

i'm more or less interested in side-effects; if his stand works out great for any augments, cool, but if it doesn't, i'm really interested in how badly it'll mess with the user, and for how long.
