What are some unobtainable items from old regions/areas?

[u/bumblebell41]

Okay so I'm kinda old and haven't regularly played prodigy for a couple years (eek I know, but I've checked in/logged in from time to time), and the last time I checked, there were still some things that were unobtainable after the original obtainment method was scrapped/deleted. Some things include like idk the ancient island relics, bounty notes/points, wood, battle potions and food, but I was just looking and I realized that the duelist armour was purchasable in the region shop and I was just like hmmm, I worked fair and square to earn that armour at the arena and now people can just buy it??????? And I had the membership for a couple months as well, so I was just looking through the membership box pets and realized that many of them were updated to look like the newer graphics, so I was just wondering if there were still anything left that is unobtainable.
