At night, head to the smallest field of The McQuibble Farm ( -1685, -25, -41 ) Copy/waypoint -1685, -25, -41, Professor Heribert will spawn here; speak to him.
Two low levels or even a solo low level character with a merc may do this if you are patient.
High levels can solo this without any issues, so it could happen that you spawn the mobs and someone takes them before you have a chance to engage. Just be patient. In two Norrathian hours the quest giver will be back. Don't talk to him if you see others around. If you did talk to him and someone took the mob, the simplest solution is to delete the quest, go back to the tavern, talk to the professor to restart the quest and then go back to the field. This is the only quest that takes a bit of finesse, but usually drops fabled loot that's useful at low levels (70 or less).
Rewards[]
At least 54s to 1p50g at level 90 (Scales with player level)
