This condition affects one or more of your limbs.
If your arm is Maimed, you cannot use it, and must let it hang limply at your side or hold it tightly to your side. You do not have to drop anything you are carrying in that hand, but you cannot use that hand to manipulate anything (draw a potion, grab a flag, etc.)
If your leg is Maimed, you must go down to one knee. You cannot walk or run on that leg. You are allowed to crawl, however we strongly advise you to consider the terrain you are in and whether it is safe to do so before you attempt it.
