Some of the percentages and actual results in the game have made me wonder, but in terms of the jeweled chest conversion, keep something in mind: It is a 1% chance each time, individually. That means all players (not individually) would receive 1 jeweled chest for every 99 others get, on average. The key words are "on average". I once played a game that implemented an event where you could earn tickets in the game, or buy them with real money in mass amounts, and using the tickets would get you decent prizes, but have a 0.1% chance of scoring you a special item that would have the game creators contact you directly and you could ask for ANY item in the game, regardless of whether or not it had gone rare (unavailable) or not. There was a certain item considered BY FAR the best in the game, but was only available to players who were around when the game first started. You could ask for that if you wanted. I sunk $50 into tickets (equaling about 500 tickets), used them all, got more rewards than I knew what to do with, but no special 0.1% item. Because of some technical issues in the game, the devs had to refund everyone all the tickets they had used, but because it was the devs' own faults, players were allowed to keep their prizes and re-use all their tickets again, so I did. 1000 tickets down the hole, nothing. Meanwhile, I heard of people getting the 0.1% item within 5 tries.

Sometimes, lady luck just wants to piss you off.

Thank you for the note Viktyr.

It's not a bug, just a period of bad luck.

The chance of conversion is unique to each chest drop. There is no pity timer.

So first you need to be getting a chest win from a boss kill, then the dice need to roll in favour of an upgrade for that chest.

At 459 chests, the odds that at least one conversion should have occurred are slightly greater than 99%. I currently have 563.

would be great for number crunchers if the game didnt count bought jeweled chests (or ones obtained from event objectives) toward the count of jeweled chests opened.
