You can order this farm daily. The only condition is that you must have an unclaimed reward from the Share button in the Krypt. If the reward is claimed, you can order a farm the next day - it is updated once every 24 hours.
The probability of the farm working (that is, that there will be as many crystals as stated) is 80%. If the farm does not work (there are fewer crystals), we will complete it the next day
