Crafting system

The game implements a mechanism for improving items by combining them.

With a certain probability 3 items of the same grade can be turned into one grade higher.

The higher the grade of the item, the lower the chance of getting a new item. Items in the process of crossing are burned.

The chance of successful crafting depends on the quality level of items used, as well as a number of hidden parameters

Common - Uncommon	~30%
Uncommon - Rare	~20%
Rare - Unique	~10%
Unique - Legendary	~2%
