IMPORTANT
This is not exploit is nothing is just stupidity
There are 2 probabilitys while open chests (if it is a treasure box of course)
1 - probability of being opened
2 - probability of drop high amount of adena or item (enchants)
First one if ur key is same level as the chest the prob is 100% if not it decreases
Second one depends on ur level and the box level, it doesnt matter the key
so to do this u just need to know how to read IG
