Clone

This spell creates a duplicate of a human, demihuman, or humanoid creature. This clone is in most respects the duplicate of the individual, complete to the level of experience, memories, etc. However, the duplicate really is the person, so that if the original and a duplicate exist at the same time, each knows of the other's existence; and the original person and the clone will each desire to do away with the other, for such an alter-ego is unbearable to both. If one cannot destroy the other, one will go insane (90% likely to be the clone) and destroy itself, or possibly (2% chance) both will become mad and destroy themselves. These events nearly always occur within one week of the dual existence. Note that the clone is the person as he existed at the time at which the flesh was taken, and all subsequent knowledge, experience, etc., is totally unknown to the clone. The clone is a physical duplicate, and possessions of the original are another matter entirely. A clone takes 2d4 months to grow, and only after that time is dual existence established. Finally, the clone has one less Constitution point than the body it was cloned from, and the cloning fails if the clone would have a Constitution of 0.

The material component of the spell is a small piece of the flesh from the person to be duplicated. The DM may in addition, add other stipulations to the success of a cloning effort, requiring that some trace of life must remain in the flesh sample, that some means of storing and preserving the sample must be devised and maintained. etc.
