On the first issue, it just seems like the deep dark would be made for quarries, being ore dense yet dangerous to traverse, so I'm just asking for you to consider it. As for endgame trading, is it allowed to trade an endgame item for an equally endgame item? Or if they both are able to, but it's more convenient to trade them. Like trading some quantum for kami if they both would be able to. Just curious.
As far as I knew, quarrying in the deep dark on monster was already permitted.. @Founder ? if not I don't see any reason it can't be. As for the endgame items, I wouldn't say it's okay for someone to trade Quantum armor for Kami gear if the person getting the Kami doesn't have Kami unlocked, but I've already told @SphericalHelix that it's okay for people to buy Kami gear from someone else as long as the buyer already has the research unlocked and has made the item at least once before -- so you can't unlock the research and then immediately get someone else to do the actual crafting of it for you, but if you've made it before and then lost it due to death/glitch/etc then you can pay someone to make you a new one.
I tested by trying to place an enderquarry in there, and it refused, so i doesn't as of now work. And I think that we can all find those terms of trading endgame items agreeable.
I tried that, even sitting there watching youtube for half an hour so it remembers where I'm supposed to be, but when I tried to reconnect it never put me back in the deep dark, and the quarry still does not work.
