- Talk with Thierride (S) to start the quest.
- Obtain 2 Lufet Salts by defeating River Crabs in West Ronfaure at the Knightwell.
- Return to Southern San d'Oria (S) and speak with Thierride (F-8, bottom/middle).
- Trade him one Lufet Salt for a cutscene, then trade another.
- Zone before talking to him again to get your reward. You can use Retrace to zone and run back to Thierride.
- You may reobtain this item once per conquest tally after completing the quest once. As long as you do not have one in your possession, he will say he's "just finished making up another batch", and will give you a Angler's Cassoulet. There is no need to trade him further salts.
