Armor enchantments should slowly time out and reduce to a lower state. The rate could be either linear, i.e. a point of enchantment expires every 2000 turns, or it could be faster at higher amounts of enchantment, i.e. a +1 armor is pretty stable but a +5 will decay to +4 fairly fast.

Add a minetown variant called “Wine Town”. It would largely follow the regular Minetown precedents of having the Watch, a temple, a (high probability of a) general store, but would also have at least 2 potion stores, a couple random potions of booze lying around, and a large “drinking hall” room.
