First, the sparkling chests, the most complex one. There are 6 different options with the chance of being picked as below.
1. 2% chance
2. 4% chance
3. 6% chance
4. 20% chance
5. 30% chance
6. 38% chance
Note that the last option is also what I call the "fail" option. That is, for many of the other cases, if some requirement has not been fulfilled with the drops done, there will be additional drop according to option 6.
1. The game will make a chest TC drop with a desired quality of unique. If the drop fail for a magical+ test, it will make another chest TC drop with a desired quality of unique. If that drop also fails for a magical+ test, the game will also make a drop according to option 6. Note that a chest TC drop can still generate, say 3 unique items for each of the two attempts and yet fail, as long as the first item in those two attempts were items that can't be magical.
2. The game will make a chest TC drop with a desired quality of set. If the drop fail for a magical+ test, it will make another chest TC drop with a desired quality of set. If that drop also fails for a magical+ test, the game will also make a drop according to option 6.
3. The game will make a chest TC drop with a desired quality of rare. If the drop fails for a magical+ test, it will make another chest TC drop with a desired quality of rare. If that drop also fails for a magical+ test, the game will also make a drop according to option 6.
4. The game will make up to 10 chest TC drops with a desired quality of magic. As soon as 3 of them pass a magical+ test, the 10 attempts are aborted.
5. The game will make up to 10 chest TC drops with a desired quality of magic. As soon as 2 of them pass a magical+ test, the 10 attempts are aborted. It will then drop a number of gold piles equalling 7 minus the numbers of failed magical+ attempts done so far.
6. The game will make up to 10 chest TC drops with a desired quality of magic. As soon as 1 of them pass a magical+ test, the 10 attempts are aborted. It will make a number of chest TC drops with no desired quality (thus normal quality probabilities including MF occurs) equalling 4 minus the numbers of failed magical+ attempts done so far. Next it makes 5 gold drops, 2 heal potion drops and 2 mana potion drops.
