Hello. I would like to offer a good option, at the expense of stones.
Create or make an NPC, a vending machine / where you can exchange stones, 1k2 - 1k3 for example, you give 2 blue stones, you get 1 yellow. And mb buy stones for General badge
It is already very difficult to farm stones in the game, given that there are an average of 4-6 people in the group.
Given the right colors for each item, this complicates the process by 500%.
It is also very difficult for beginners and they cannot realize themselves because of this.
