Cajoling a Cudgel

Cajoling a Cudgel is an unmarked quest

Detailed walkthrough
Locate Luke's Find, a key which unlocks the sealed sewers. It can be found on the bodies of two dead prospectors, "Sweet" Jill (in the east central sewers) and "Blind" Luke (in the central sewers).

Once obtained, the Courier can enter the sealed sewers and, after fighting several feral ghouls, find the unique weapon The Humble Cudgel on a prospector.
