EnchantLevel: The EnchantLevel code is nothing more than the level of enchantment that will come with the weapon, or armor, when you open the box. Currently this 15, so the item will come +15
minCount: The minCount code is simple, it is the minimum amount that will come, it would be like a roulette wheel, the minimum amount must always be "1". If it is "0" nothing will come. Therefore, if you enter a minimum quantity "1" and a maximum quantity "3", it can be between 1, two and up to 3 items.
maxCount: The maxCount code is basically the opposite of minCount, the difference that here will be the maximum of items that can come when you open the box, if you put maxCount = "15" there will be a maximum of fifteen items.
