Combine two items to make another

I'm in need of a scriopt or something similar where I can combine two items together to make a new one, like the rarer the two item the rarer the out product. thanks.

:roll:
now that's just one of the cases in which i am shocked i am the first to say
USE EVENTS

it will actually be harder and longer to use a script for that AFTER you completed the script

here is a basic thing,  2 items, you'll need more:
make a refiner npc

show choices:make me item Z!,show me what item Z needs,make another item,  damn maybe later
upon make item z:
-if item Y is possessed then
--if item X is possessed then
---remove items: x,y
---add item: Z
---message: here you go! item z! the best i got!
--else
---message: sorry you still need item X
-else
--message: sorry you still need item Y
upon show me what item z needs:
-message: item z needs item X and item Y!
upon make another item:
(Same as item z event but with another item)
upon maybe later
(end of the event)

thanks for that buddy, i never thought of it that way

you can either use events or:
