Missing Limbs and Mobility
Source GM Core pg. 22
Characters in Starfinder have a wide variety of body types and appendages. While rare, some items require certain limbs or other body parts to function or wield. It's important to allow these items to work for all characters. You're encouraged to create an alternative form of such items whenever desired, turning boots into wristbands for a character without legs, for example.
A character with a missing hand or arm might need to spend 2 actions to Interact with an item that requires two hands, or otherwise compensate. Using a two-handed weapon is not possible. Someone missing a foot or leg might take a small penalty to Speed, and if they have no legs or are unable to walk, they might use a wheelchair, hoverchair, vehicle, jetpack, flight magic, or other items, armor upgrades, and augmentations. Prosthetics are common and come in many different materials, styles, and sizes. Characters can acquire prosthetics in most settlements across the universe or create them on demand at UPB printing kiosks. Prosthetic limbs are an augmentation that cost 5 credits, and don't count toward a character's implant limit.
