I added Drop Tables to our Monster DB and Item DB (Details View). Some % values are missing but in general it looks pretty solid (I compared it on the korean and international servers). I checked item drops while I played and it matched the database values.
What do you think about the drop tables? You can see that it’s not just about items in an area or level range but that each monster has individual drop items.
Examples:
Meteor is a pretty nice “rare” shield in the beginning. It’s only dropped by the “Mini Boss” Big Red Kepa (1% Chance) as it seems.
