Regarding loot boxes, when opening boxes with NFT robots, the percentage chance for a given rarity is provided. However, in the game, when opening boxes with equipment for crystals, there is no such information. I made a few purchases in the game and opened equipment boxes, and I always got items with at least rarity level 4 or higher. After some time, I bought a pack of crystals and opened two boxes from which I got items of level 1, the same as from boxes for ash. To me, this seemed like a bug, because how can you put something like that in boxes for money xD I reported it on Discord, but the condescending response about randomness I received after more than a week did not convince me, so I just requested a refund in the App Store. Additionally, I reopened those boxes later with the remaining crystals, and this time I got only level 5 and 6 items. In summary, openly providing the chance for a given weapon or equipment rarity would cut down on speculation and potential dissatisfaction. Best regards.
