I am really puzzled. when i used @item2 to put item into an item i cant do it. how come i saw others do it?

They used @item2. You can put weapons on weapons, and armor. Just put that item as the card ID instead.

@item2 ITEM_ID 1 1 +10 0 ID ID ID ID

Item_ID = ID
1 = How many
1 = Is it Identified?
+10 = Refine Rate
0 = Broken?
ID = Card 1
ID = Card 2 ...etc
ID
ID
