Hump

The subject has a fatty hump which can store food and water.
Type: Minor positive.
Effect: This mutation manifests as a large, fatty growth on the subject’s back. When full, the growth is very prominent; when empty, it is much less noticeable. A full hump can store a week’s worth of food and water. This will automatically be used to replace any missing food or water; if the character is on half-rations for a week, she consumes half of the hump’s reserves. The hump replenishes itself at a rate of one day’s worth of sustenance for every two days of normal eating and drinking.
Biotech: Implant, Graft.
