item_rate_adddrop: 100 = 1x / official rates
item_drop_add_min: 1 = minimal drop = 0,01
item_drop_add_max: 10000 = max drop = 100% drop chance
treasurebox the same
Lets say you edit
-> item_rate_adddrop: 100
to
-> item_rate_adddrop: 1000000
This would make items wich drop rates are at 0,01% drop at 100%.
Other items that have a drop rate above 0,01%, lets say 1%, would be dropped at 10000% wich would make them a negative drop.
But thanks to "item_drop_add_max: 10000" the max drop chance can only be 100% means that the items cant go above 100% drop chance.
I hope you understand what I mean. I sometimes talk in gibberish
