Old files - item duplication bug

01/12/2013 13:19 VEssence#1

as far as i know you can duplicate your items via using stall, stall network and pet
can someone explain that how to duplicate items for stackable and non stackable items ?

Put a Arrow Stack (Amout:50) in a Exchange Window, open Stall Network. The items in the inventory are now unlocked again. Switch the Arrows for example with a Global Chatting Scroll (Amout:1). Close the Inv on both Clients, finish the exchange and teleport. Now you got a Global with Amout 50.

On the stall it is nearly the same, you close your own stall window client sided and switch the slots. Then you buy it with another char.

Never heard anything about a pet item duping bug, does anyone knows more?

Telling from the explanation of GoneUp.. I guess you're using an old database that has the procedure "_STRG_MOVEITEM_P2P".

Please remove the..

Code:

	DECLARE @Old_Item_Data INT
	SET @Old_Item_Data = 0
	SELECT @Old_Item_Data = Data FROM _Items WHERE ID64 = @ItemID_From
	IF (@Old_Item_Data IS NOT NULL AND @Old_Item_Data <> @Data)
	BEGIN
		UPDATE _Items SET Data = @Data WHERE ID64 = @ItemID_From
	END

..part and try to exploit it again.

Cause this would mean, Client holds Data (50), procedure grabs ItemID + wrong Data (1) of the Slot the Arrow were in, recognizes that Client Data (50) != Item Data (1) of Slot, updates Data (50) of Item (Global). Such updates require the player to teleport.

It's just a guess, I couldn't test it on a live server unfortunately :(
