What is the valid moment that item become valid for everyone else's chronicle? Do you have to be in the game in the moment it dropped or the moment it was picked or the moment it was identified only?
I was thinking about putting a bounty for whoever drops a unique caduceus in your game, so I join and you pick/identify it.. would that work? Have anyone tried it yet?

Moment item drop on game you need be in same game and item get ID

Wow that sounds like it could work. Nobody that I know has tried it yet.

Pretty sure you gotta be in game BEFORE it drops
