I can see the appeal in an item that increases box rewards, but I think this kind of item would be very hard to balance.
If you increase the amount of souls a box gives, it would be a must buy and the item would be too broken.
If it increases golden statue buff drop changes, then it would make a sense.
The box walking breaking mechanic should not be the selling point for the item, it's kinda useless honestly other tham making box farming marginally more efficient which I guess alright.
