[Release]Modify Magic and Rare Items Drop Rate (VSRO188)

Hello,

Since many people keep asking about it, on the other hand @exo keep asking me for it too, so here is the example function for the RareItems Drop

Note: Most of the silkroad uniques drop factor is hardcoded and limited for example the WhiteSnake can only drop from 1 to 3 elixirs, but Roc can drop between 50-300.
