The Cursed Amulet

From publisher blurb:

The Goddess Shar, of the trickster domain, has created a cursed amulet and placed it in a nearby cavern for curious adventurers to find and take with them. Any creature or player who touches this amulet gains incredible good and bad luck at random times. Shar can communicate with whomever is cursed by this amulet and try to get them to do ridiculous tasks. She will randomly cause that person or persons to have extremely good or bad luck, whichever is funnier to her. A woman named Lucy, sister of Harrison, has stolen the amulet. Now Lucy and Harrison want to rid themselves of the amulet and need the party’s help returning it to the cavern. Return the amulet to the shrine in the cavern to remove the curse.
