[Help] How to understand Itemdrop.txt (S16 by MUDevs)

[smth]

the file look like this:

//Index   Level   Grade   Option0   Option1   Option2   Option3   Option4   Option5   Option6   Duration   MapNumber   MonsterClass   MonsterLevelMin   MonsterLevelMax   DropRate   Comment

6159      0       0       *         *         *         *         *         *         *         0          *           *              12                150               1000       //Jewel of Chaos

It's easy to understand these fields:"Index Level Grade Duration MapNumber MonsterClass MonsterLevelMin MonsterLevelMax DropRate".

But it's very difficult to understand "Option0 Option1 Option2 Option3 Option4 Option5 Option6".
the option4 seems to set exc value.
i want to set the monster drop an item with only one exc prop,but i tried 0 to 6, and the item had 2 exc pro at least.

Option 0-6 all link to ItemOptionRate.txt in Data/Item.

Lets say in Excellent you want max 1-3 opts. then in ItemOptionRate you will pick //Exc Option (EventItemBag) (1~3) which is #21

So example Kris with this usecase

//Index   Level   Grade   Option0   Option1   Option2   Option3   Option4   Option5   Option6   Duration   MapNumber   MonsterClass   MonsterLevelMin   MonsterLevelMax   DropRate   Comment
0000      0       0       *         *         *         *         21         *         *         0          *           *              12                150               1000       //Kris

Good luck buddy.

thx again.i almost understand how it works.
but what does the value "*" or "-1" mean,there is no "*" or "-1" in ItemOptionRate.txt

[Severithe]

It usually means everything or all, so if you don't implicitly specify the numbers, it can drop everywhere.
