Chest explanation

When choosing the items to appear in each chest, the game first rolls to establish the maximum number of items in the chest.

• For silver chests, the odds are 5.00%, 9.50%, 85.50% for 3, 2, and 1 items respectively.
• For gold chests, the odds are 1.00%, 4.95%, 94.05% for 3, 2, and 1 items respectively.
• If the player is playing online in the Definitive Edition and the enemy is a Tyrant with a silver crown, the chest is guaranteed to contain at least 2 items. If the enemy is a Tyrant with a gold crown, the chest is guaranteed to contain 3 items.

Once the maximum number of items N is determined, the game loops through the list of items that can appear in the chest (the "drop table"), adding them to the chest until N items have been added to the chest. Items are added to the chest as follows:

For each item in drop table:
    roll chance equal to that item's rate
    If success:
        Add item to chest
        If number of items in chest = N: Finish, else: Continue
    Else:
        Continue
    If end of drop table is reached: Go back to first item

This process always terminates by the end of the Nth cycle, because there always exists at least one item with rate 100 (guaranteed) that will be added each loop if all other rolls fail.
