Barri Advanced

For the new rewards the game rolls chances in multiple drop pools. If it succeeds in the roll for a pool you'll get one of the items from that pool (so you could get something from every pool if you were lucky enough). Each item you get from each pool is put in the chest along with the gold/pouches.
  • Pool 1: 100% chance of being accessed.
    • ?

  • Pool 2: 10% chance of being accessed.
    • ?

  • Pool 3: 7% chance of being accessed.
    • ?

  • Pool 4: 3% chance of being accessed.
    • ?

Then the game calls AddOldReward() which has all the stuff that existed before the revamp.
The first part of the old rewards is guaranteed attempts like an upgrade stone roll (50 / 1,000) and junk.
Then the game rolls to choose which unique loot pool to use, so each chest could pull from a separate loot pool.
