Create long ago for a harper who become ruler of a small kingdom, it was meant to tell friend from enemy and give aid to any considered friend. It is a tall silver goblet, finely made, and etched with a scene of a harper/ bard. Three gems are one the base on the goblet, an emerald, a ruby and a diamond. Etched above the emerald is the word “har”; above the ruby “rue”; and above the diamond “hep”
It depends on how the cup is used
If the emerald is touch and the word “har” spoken, anyone drinking from the cup is overcome by uncontrollable giggling for 5 minutes
If the ruby is touched and the word “rue” spoken, anyone drinking from the goblet is compelled to tell the truth for 3 minutes and them forget anything they just have said.
If the diamond is touched and the word “hep” spoken, anyone drinking from the goblet is healed form 1 desease or wound.
