This evil spell is a variation of the Trap the Soul spell. It forces the soul of the victim (not the body) into a previously prepared gemstone. The victim loses all of his self-will. He will follow the commands of the last person to touch the gemstone.

The victim is not dead, but neither is he alive. As long as his soul is in the gem, his body will not age. He will continue to function until completely dismembered. In effect, he has double the normal amount of hit points. However, the damage must actually harm to body (i.e. electricity could burn and blow the body apart, but cold could only slow it down). Piercing weapons cause only half damage, and no magic affecting the life force or the mind will work on such a victim. The spell's recipient keeps his combat skills as in "life" (i.e. THAC0, specializations, Backstab, etc.). However, he cannot use any psionics or magic. He no longer eats, sleeps, breathes, or even heals (only a Wish can recover lost hit points). He can still speak in any language known.

To cast this spell, the wizard must have a gem worth 1,000 gp per level or HD of the victim. The gem must be enchanted with an Enchant an Item spell, followed by an Energy Drain spell, and then a Limited or Full Wish. The intended victim's name must be engraved upon the gem as well. The spell must be cast on the night of the victim's birthday and the gem must be soaking in the blood of the caster and the victim. The actual ritual takes a full hour to complete and cannot be interupted or both caster and victim die (save vs. death). At the end of the hour, the victim must make a System Shock roll. If it fails, he dies with no chance of resurrection. If it succeeds, the soul is sucked into the gemstone.

To return a character's life force, the gem must be powdered and consumed by the victim. When this occurs, he must make a second System Shock roll. If successful, his soul returns to his body. If not, he dies. If his body has taken more damage than he normally has hit points, he dies as well.

There is no limit to the number of slaves a character may have at any one time, but there is no telepathic link between master and slave. A slave retains full Wisdom and Intelligence, just no will. He will do as instructed to the best of his abilities. Original ideas and plans must come from the master.
