Obtained from doing the 'Further Research Quests'. You got that immediately after getting the discovery of the quest you choose. So far, you get 1 per quest.

You can get one Orichalcum from this. Not sure how rare it would be, but the chance is i get 3 Headache Medication(s) and Storage Man's Rigging more than this.

You can get one Simple Sailor Equip. Repair Tools from this. Must be pretty rare.

1x Shipwreck Map Piece (yes, just one)
1x Explorer's Household Medicine
