Maleficient is an evil witch on a quest for true immortality. Until she accomplishes her goal, she uses a midpoint form of magic called reincarnation in order to buy her more time and keep her alive. Reincarnation magic allows an individual to reincarnate themselves after death in the body of another human. Maleficient keeps a number of host bodies trapped in a deep sleep to take control of in case she is killed by her enemies or dies of old age.
These bodies are stored together in a secret dungeon only she can get to, away from prying eyes and kept safe in stasis. However, while this magically induced sleep keeps the individual alive in stasis, it presents a problem to her. Muscle atrophy is defined as a decrease in the mass of the muscle; it can be a partial or complete wasting away of muscle, and is most commonly experienced when persons suffer temporary disabling circumstances such as being restricted in movement and/or confined to bed as when hospitalized.
This means that even if the spell is successful, the witch would be completely handicapped. This would make keeping these bodies stored useless as she would be completely crippled.
How can she overcome this problem? What other issues am I likely to face with preserving the victim with this spell?
