Rules column in ItemDropTable.txt?

[NvrGnaStp]

I was wondering what the rule column was for in ItemDropTable.txt, anyone know?

Checksum = minLv +maxLv

I fucking love this section, the greatest minds come out to play at the most obscure times.

I'll predict the direction of this thread, question about x, turns into information about y, ends with argument over z.

I am sorry , i misunderstood the question
Hope this time it will help
If you set item for [DrItem1] then [DrItem1R]= the rate, [Rule1] = r, [Num1]= -1
If you set nothing for [DrItem2] then [DrItem2R]=0, [Rule1] = - , [Num1]= 0

It's not just copy and paste the other rows. He was asking what they are for? What do they do? And how they are used?
