From the in-game information when talking to the NPC: "Complete any of the role quest lines available at the Wandering Stairs...".

Either that information is wrong and only the lvl 80 one counts, or the information is correct and any quest counts, but you're required to do the quest while also being on the MSQ for the item to drop.
