Rare Treasure Chests....

[Energizeric]

I think there should be a mythic rarity item called a "Treasure Chest" which when opened contains a random amount of gold between 1m and 10m. It should be an extremely rare drop that comes from any boss, elite or non-elite. But so extremely rare that most players will never see one drop. We are talking maybe 1 in 10k drops would be one of these. They can be opened or sold like any other item.

I think it will create the very rare possibility of striking it rich while farming any dungeon, and will give incentive to kill the boss in most dungeons. Kind of like a rare chance of winning the lottery.
