Lua [tfs 1.3] combine 2 items NPC

[Cebal]

Hello guys! Maybe someone will be able to help with with a pretty simple script. Im looking for NPC which can combine 2 specific items to 1 other item. It would be nice to have an option to talk to this NPC and if I have 20 of each items I could exchange 20 at once, or less. Thanks!

Try this, and let me know how it goes.

    <look type="138" head="57" body="59" legs="40" feet="76" addons="0" />
</npc>
