Erdlu Egg

This spell causes an old erdlu egg filled with sand to become a fresh erdlu egg, with contents fit to eat. On any other world, the duration would be too short to do any practical good, but on Athas, the disappearance of the egg's water will not come about until after it has already been sweated out of the recipient's body. Elf nomads developed this spell as a means of creating an emergency food supply. Once the created food is eaten, the shell disappears, so a new shell is required for each casting. Thus, possession of this spell doubles the number of erdlu eggs any tribe has.

The material component is the old erdlu egg.
