The Brightbox.

Different Prize List, and it moves randomly like the darkbox.
maybe once every 4 hours both are in the same room for a short time.

During this phase drops that are usually discarded are removed from loot list and the loot chance for better stuff is increased.
And the damage they do is increased some as well.
at the end of this phase, a random person gets dragged off by both boxes to a special room.
In this room is a prize box, with a good prize/gift for that person.
Only can be won 3 times per character.
