Yes the 50% is a total gamble. They retired some, they added some, and they changed the drop chances this season. It could be anything and I would require a lot of treasure-draw data from season 4 to really find out what our chances are in this season. But assuming they are the same as last season, it would still be a very hefty amount of $$$ to get a crystal engine going. But my own luck in season 4 is quite bad and it so far seems as if it only got worse but I need way more data.

Sadly, some of the draws are from S-Rank events and some are not. Sorry about that. I wish I had it more accurate but I don't.

I hope that during next S-Rank event when people open a lot of chests, they will screenshot their draws and if enough people post their results here we can quickly figure it out.
