you don't Dbox them to yourself?
Since I was aiming for Hoxne pieces and only 1 character in the group has it, there's no need to d-box it, because the other 5 members in a party don't have any Hoxne pieces.
I don't do dbox items, mostly for time savings, but my reasoning is that: Adding players to a Trove party where at least 1 character doesn't have an item is sufficient to make any drop appear in the pool. Obviously, I can't prove that this reduces collisions or creates the necessary degree of variance needed to make for an awesome Treasure Pool. However, it's very possible that when we see a "missing item" in the pool, that it's much more likely to be a Malignance drop, than a Hoxne piece.
I hope this makes sense. I know my experience is anecdotal, but I have several thousand Troves under my belt since 2018.
