never heard of tonpc
@item2 [item id] [quantity] [refinement] [placement] [element] [card] [card] [card] [card]
so in theory:
@item2 1530 1 10 10 10 4305 4305 4305 4305 would make a holy[?] +10 Quad Explosive Mjolnir
but really it is a glitched item that appears to be broken, but isn't and cannot be repaired.
Err, @item2 1530 1 1 10 0 4305 4305 4305 4305 would be the correct structure.. also it's
@item2 [ItemID] [Quantity] [Identity_flag] [refine] [broken_flag]
whereas identity_flag means that a 1 identifies the item and 0 is unidentified
broken_flag 1 is broken 0 is not broken, that explains your 'appears to be broken' mjolnir
also, 4 cards wont work with an item with no slots... if it has 1 slot and you slot 4 cards in then only 1 card will work. hope that helps
edit:
tonpc warps you to an NPC, you have to do @tonpc name
you don't have to be on the same map just the name will do
it won't work if you, for example, @tonpc knight since there are other knight npcs (same name) it'll only work with NPC's that have unique names such as Jayon, Kellion..
