I know that takes time. But you already have the animations needed for this. The arena chest reward animation. What is the name of the other game??
The animations would be a quick re-use or would take a short time to create some new ones. The issue comes with coding the actual feature.
That would touch not only the message system, but individual character files, the overall save file, online/offline status, some way of server “tracking” (time, date, qty, etc) and since we don’t currently have that building those supporting features would take quite some time.
Its just an idea that you could implement in the future. Perhaps in DQ3 or DQ4.
