The amount of loot from the boss

[xBarselonx]

Hi all!

In the worldserver.conf settings there is a Rate.Drop.Item.ReferencedAmount, the default value of which is 1. As I understand it, this setting is responsible for the number of items dropped from the boss in raids. I set the value Rate.Drop.Item.ReferencedAmount = 0.5 and there were fewer items dropping from the boss and I was happy with that. But another problem arose when I sift ore or grind grass (in this setting Rate.Drop.Item.ReferencedAmount = 0.5) dyes and gems do not appear in the bag.
Help me how to solve this problem. The main goal is to reduce the number of items dropped from the boss. I play alone on the server.
