Benefits: You can build
cybernetic attachments. You must first make a
Wealth check against the purchase DC of the attachment (to acquire the necessary components), then invest 24 hours in its construction. At the end of that time, you must succeed at a Craft (mechanical) check (DC 30) and a Craft (electrical) check (DC 30).
If both Craft checks succeed, the
cybernetic attachment functions properly and can be installed at any time (see the
Cybernetic Surgery feat). If either or both checks fail, the attachment's design is flawed; another 24 hours must be spent fixing the problems, and two new checks must be made at the end of that time.
