By the power of this spell song, the life force of someone dead, or on the brink of death, can be temporarily sustained. To accomplish this, the Wishsinger must be in actual physical contact with the recipient. The magic of this spell song will bring the recipient's hit points back to zero, no matter how far in the negatives they were before. However, if the recipient is dead, he must have died within one round per level of the Wishsinger for the spell song to have effect. As long as the force of the spell song is in effect, the recipient's hit points remain at zero. The spell recipient does not regain consciousness while the magic of the spell song is in effect. Once the spell song's effect is expended, the recipient begins to lose hit points at a rate of one per round until dead -- or until some other outside force intervenes. This spell song is particularly useful in sustaining the life of poison victims or victims that have hit points below -10. Upon singing this spell song, the spell recipient must make a system shock roll or lose one point of Constitution for a period of 2d4 weeks. Only non-evil* Wishsingers can implement this spell song.
Of course, most Wishsingers will not allow a person to die after the spell expires. More likely, the Wishsinger will use this song to raise the wounded individual's hit points back to zero, end the song, then sing Song of Healing to bring the target back into positive hit points.
Similar Spell Note: Raise Dead
* An evil Wishsinger can sing a dark version of this song, The Song of Lasting Death, in which a recently slain individual can be reanimated as a Zombie of equal hit dice.
