Firstly, to describe it, this will let you store ALL MATERIALS and take them out (whether that be for weekly loot quests or if something like crafting is ever added)
There would only be one location for this and it'd be at Gnome Capital, so after you finish an adventure and want to store your loot then you have to go all the way out (loot sellers will still be in every biome if you just want to collect and sell and then leave.)
Secondly, why? The fish bucket has really changed how loot gathering feels, obviously because it's an entirely new system, but Also because all fish you collect can be stored in a permanent inventory to be sold or traded. This was most prevalent with today's fish quest where if you fished for a good while the day prior you could get it done instantly and go back to collecting.
What the Adventure Vault would let you do is give you a reason at ANY TIME to do dungeons (i know you can sell them for beans, but the comparative value and time sink comparison is terrible and while it should exist as an option this would mean instead of selling them for beans you can save them for the next weekly loot quest or for things like crafting or rewards like the fish crown if that's ever added)
This would breathe TONS of life into ALL dungeons as you'd always find someone chipping away and collecting resources. This would also give a lot more value towards the legendary sack since ANYTHING you pick up could be stored for later, so you'd be encouraged to pick anything you come across.
I should also note that despite fish being an infinitely farmable resource, loot isn't and should stay that way. I'm just asking for a similar infinite storage option for loot.
