Prosthetic (leg/foot)

Prosthetics are usually metal and custom made to replace whatever portion of a limb has been lost.

While you are standing on your prosthetic, you cannot gain advantage or expertise dice on saving throws made to resist being knocked prone, and you take half damage from caltrops, spikes, and difficult terrain that deals damage. Depending on how your prosthetic is constructed, you can use it to store up to one concealed Tiny item (DC 15 Investigation or Perception check to notice).
