ooo I love this idea!!! I’d love to see this in game!!!
When you submit an item, does it get taken away from your inventory? If it does, won’t it be extra space to put items? For the repeatable tasks/quests/collections can you turn in multiple of the item for a collection? So for 5% or less rarity collection, can you turn in 10 grand pianos?
Also a question: Eg. Can you submit 16 stone eggs at once? Or do you have to submit 15 and finish the collection first, and then submit the 1 stone egg?

hm though imagine 4 noolong statues: From hoarding, from task, from crafting, from adventure. What if we can summon a big one using all 4 xD

1. My idea was that yeah if you submit an item, it gets taken from the inventory, and yeah technically in that case, it'd lowkey be a bit of extra storage heh

2. If a collection asked for something like 5% rarity or lower deco then yeah, 10 of the same rare deco such as grand pianos should, ideally, work! Well, unless the collection requirements specify that they need to be unique items

3. I think, depends a lot on how the code would be made to work by whoever codes it. It'd definitely be cool if for, say 15 stone eggs collection, you could submit 60 stone eggs at once and get 4x the rewards instantly, but yeah I can't really make such predictions for if this feature ever does become a thing
