Dear Lords,
 
We are going to announce the in-game chest probability today.
 
Generally, the total probability of permanent items is 12%, and the skins is 3.6% (if there are two skin colors, the total probability of two colors is 3.6%) If there are fewer items in the chest, the total probability of the permanent items and the skins probability will be raised.
