Cuisinart behavior
Format: use cuisinart
Format: use cuisinart limited or legendary item confirm
Put the items you want to scrap inside the cuisinart, close its lid, and use it. For a fee it grinds the contents into components -- raw material for crafting -- shredding objects into chunks and chunks into dust. Load it with five identical heaps of dust instead, and it presses them back into a single chunk.
A craftsman's work is the exception: it grinds down by its blueprint, one pinch of dust for every chunk that went into it and nothing for the dust. Not every item can be broken down, and it refuses to start with more than ten of them inside, counting whatever is stuffed into bags.
A limited-run item won't go in through the lid: name it after the machine and the cuisinart warns you first, then pulls it in once you repeat the command with the word confirm at the end. A ground limited item is gone for good.
Legendary pieces, dropped or crafted, can't be ground any other way and go in the same way. They pay for it: their parts come out twice, plus one scarce part for sure (mithril or adamantite from metal, a precious stone from silver, gold, platinum or gems, a particle of void from anything else) and a chance of a second. Epic pieces of metal, precious metal or gems grind as usual, with a chance of one scarce part on top.
A cuisinart anyone can use stands in the library of the City of Amber. The Artificers keep a steam cuisinart of their own in their main hall: it runs free and fast, for Artificer masters only.
