Soul crystals. Realize it costs guild fund, so it's better to upgrade your hall first. Also, you can't split them, you give the entire box to 1 person.
I have upgraded the hall once and that was my plan. My idea would only work if you could split up whatever was inside. Thank you for your reply! Now I can stop wondering.
Meant extravagant, not exquisite. Didn't have the game open and that was the name that popped into my head.
Well, looking to upgrade to hall level 5 asap, so even the lowest level brocade box would have been a nonstarter without knowing what was in it, and if the items could be split up.
Thanks again for the help!
