What, did I corner the market on Japanese puffer fish? It's a little weird to be trading stacks of prepared food for things like steel plate armor. Does anyone else think maybe flour is just a bit overvalued? Or is it a just reward for going to the trouble of building power systems for milling?
I just give them masterpiece obsidian toy boats worth somewhere between 280-380 "points". Shovelling rock crafts, instruments, and toys are a great way to get rid of stone and at the same time buy cool exotic things for practically nothing (i mean, think about it... your giving them carved pieces of rock they find on the ground, for engraved steel armor sets, booze, and new types of food among hundreds of other things you cant get your self or else are too annoying to make).
I do hope the elves are immune to lead poisoning. There's got to be some reason they don't like wood barrels. Meh, lead works.
