The Sting Shop

The shop is run by an old, old man who has been old for as long as anyone can remember. They call him The Shopkeeper in the Woods. He loves mysteries, especially the mystery of what his magic items do, and he’ll encourage the players to buy the cheapest items.

In the generator above, the blacked out sections are a mystery, even to the old man himself. That's why they are discounted. If you highlight the text, then you can see what the item actually does.

I made a list. Then Type1 Ninja made another list, and included an excellent idea for the layout of the shop. Then I combined both lists and dumped them into my generator generator to output an automagic shop generator.
