The website presents a very simple interface for players to upgrade their weapons. The cube on the top is where all the action is at on the website. From here you can choose a multiplier for the roll. Then you can choose to roll which is just another way of gambling your weapon. After the roll, it is just as possible to lose your item as it is to gain a significant upgrade. If you end up losing the roll, then you’ll also lose the item and not receive anything in return.
