Anyways - You made RateDropItems = 10.0.
Like i said i don't know the package you're using, would be a good info to know.
But this should work the same way, as other packages do.
RateDropItems should describe the Amount of items dropped.
What you want should be:
RateChanceDropItems = 1.0
Change this to the wished Droprate.
Same for Spoil Rates RateChanceSpoil = 1.0
By doing this, the retail DROP RATES get Multiplied by this rate, leaving the DROP AMOUNT unaffected.
Thank you very much.
