Create a character and age them until the first year they are considered ''old'' by the game. For a Fighter or Wizard, this is 60 years old, for a Dwarf 100 years old, and for and Elf 200 years old. Use that character to battle and have them die. Allow that character to stay dead for 20 years. Take them to town and have the magician resurrect them. If done correctly, this should only have a 10% chance of success. If they are successfully brought back, they will no longer age. Use Rejuvenate to bring them to a desirable age.
