[@Zeroth] I will definitely add a few more limits, for example: the amount of food and water she has to consume to not become dehydrated and malnourished, another could be that damage to her bones could be much harder to heal from due to the lead inside them taking potentially months and years for even a fracture to heal. Other than that I'd love some suggestions! EDIT: and yeah the weight was actually calculated from the volume of a tibia and femur to the mass of lead and all that fun stuff.
