Dreamstone

Once a day this stone grants Dreams, the 4th level Low Magic spell that sends the user or another person a dream revealing something about the dreamer's future that will certainly come to pass.

As a greater magic item its magic is permanent and renews itself each day. Making one calls for the materials of a minor magic item and two months plus two weeks for each level of the spell it holds, with a 99% chance of success; one offered for sale usually costs at least twice its materials plus 2,000 G.P. per week of enchanting. It counts toward the seven magic items a person may carry or wear at once; go past seven and none of them works.
