What do you mean by demand distribution, random distribution and head distribution in Devil's Hole?

Demand allocation means that everyone in the team can roll the dice, and whoever counts more will get the items in the box. Random assignment means that the system randomly assigns people in the team, and head assignment means that the head can be given to whoever wants. The box is dead sand, which has nothing to do with this distribution method. Just to remind you that if the magic weapon is really distributed by the head, you will get nothing if you distribute it to yourself.
