28 FOUNTAIN OF YOUTH. This mystical fountain is decorated with statuettes of infants and children. A drink will reduce age by 40% (for example, a 60 year old human will become 36 years old and a 500 year old elf will become 300 years old).
A second drink will reduce age by another 90% (a 300 year old elf will become 30 years old). A third drink will make the character negative age and they will be born to random parents in 1d20+8 months time (use table from magic-user's spell reincarnation to determine reborn race).
