Prosthetic Packaging
Prerequisite
Installed prosthetic limb
Because you have one or more prosthetics you’ve learned to wire implants to them, making them easier to change out.
You may have enhancement implants applied to prosthetics designed for your use. A prosthetic modified in this manner can be removed, taking the implant benefits and drawbacks with it, as an action. Similarly, attaching a prosthetic takes only a single action, and you benefit from any active implant tied to it immediately. These enhancement implants count towards your normal limit when their respective limb is attached to you.
