They involve me making "artifacts" with a part of a riddle enscirbed on them. i put them on a mob, then give a clue to what the mob is. if they get the bust they can sell it to me for 2 qp, or if they have the entire set it's 10 for all. if they solve the *hard* riddle, it's 10 more qp.
I'm also wondering if i should keep up with the quest, or just run this single one. I have no clue if the mortals enjoy the quest.
