In the Sunken Temple area, Treasure Chest items are generated in the following way:
  1. The system selects a group based on weights
  2. The group selected has a number of items and their % chances

Once the items are generated, there is an equal chance of getting any of the items, as it is based on the chest that is tapped on.
