What's inside
Up to 100 chests can be opened at once.
How it's counted
Chances are read from the chest's tables: an entry comes up with its chance (BoxReward Prob, out of 10,000), then draws from its package — one row per draw by weight (RewardPackageItem, out of 100,000,000), so rows of the same item (different amounts) add up. Per opening = chance of getting the item at least once, 1 − (1 − p)^draws multiplied over the entries that can give it: our calculation, assuming draws are independent. The game does not show these odds.
