Itemall how to work?

How does the shop work? The ID of the item is 2160 but in the game it gives me another very different item.

You need to check ItemID and TypeID
For Example :

Power Lapis
ItemID : 95
TypeID : 7

So you need to add in cash.sdata 9507 where the number 0 is space between TypeID and ItemID

In your example you need to check item.sdata for the correct ItemID and TypeID
