Thanks in advance.
// The rate the common items are dropped (Items that are in the ETC tab, besides card)
item_rate_common: 100 = 1
item_rate_common_boss: 100 = 2
1.100 means 100% of droprate at database = 0.01
item_rate_setting * rate / 100 = output
100% * 1 / 100 = 0.01%
all droprate for card is by default 1, change the item_rate_common to 1000 = 0.1%, 10000 = 1%, 100000 = 10% and so on
2. same
