Request: Drop rate script

[Tegelsten]

Heya guys, i am new to this page, but been working with RPG maker in earlier times of my this far short life. I am requesting a script that will decide "the drop rate" more or less from a item from different monsters, like a quest item.

"You need to find my golden ring from the evil fishes"
This is the quest, and then you have to kill monster fishes, that got a drop rate on the item, is this possible in other ways ?

//Yours Robert

They have a drop item probability already integrated with XP...but that is over and over again.
