Gem

Gems are simple, lightweight items you find in the dungeon. They come in three varieties: Valuable gems, worthless glass which looks similar, and gray stones. Valuable gems may be sold for relatively large amounts of money at most general stores, which makes them valuable as a compact form of money. Glass and rocks are quite simply worthless, though they can be used for throwing if you should wish to conserve your other attacks. Gray stones are a catchall for four different objects until they are identified. Touchstones may be used to identify glass from gems, and even the variety of gem if it's a blessed touchstone. Luckstones will augment your luck rather impressively; if you have a blessed luckstone and no other luckitems, your good luck will not timeout, bad luck will, and you'll get +3 extra luck. Loadstones are a pun by the Devteam; they weigh 50 times as much as the other stones and autocurse so they can't be dropped. Flint stones have no particular purpose, but they do slightly better as sling ammo.
