As I said in the last post, I'm in the process of upgrading the whole table, so now is a good time to post the various tables as I build them. This time, I won't try to post them all at the same time.
Sorry, the prices will not all appear on the list below. The new equipment list doesn't include items that are rare or unusual for the market zone for which the list is generated (some facets of the table are random). As I said, this is what my players would see.
There are three portions. The first, in grey, includes what is available for purchase. The number column (a darker grey) shows the number of items per player that are available that week (the next week I generate a new table). The second section is the number of items and the price that the shop will pay the players, should the players be able to sell. If nothing appears on that row, the shop isn't buying. Period.
Finally, the third section is what the player is able to sell to persons on the street, either to vendors, other shops or individual people. There is a 1 in 36 chance of the player attracting attention from a guard for every sale, which would lead to an arrest (or a chase) if the player does not have a vendor's licence in that city.
I feel I am somewhat at fault here for not including a further description of this table, rather than merely leaving the table up to be viewed and perhaps investigated. It behooves me to do some of the investigation myself.
To begin with, the table includes a number of herbs which I investigated to determine what medical effects have been attributed to them throughout history. This is a painstaking process, and that is why there is a limited number of herbs here. I began work on the DMG's long list, throwing out anything I could not find effects for. Those things listed above on the table, such as acidum boricum, alder catkins, aloe vera and so on have ascribed merits. One of the things about a world of magic and D&D, whatever false effects may exist in reality, in fantasy can certainly have much as the DM allows. For the present, I have not sat down and worked out what those exact effects are. But in a game, should a player try the application of this or that, I would make a call that was readily positive. For example, devil's dung - which is listed as protecting against demonic possession - might offer a +3 saving throw vs. suggestion, magic jar or some such, if it could be eaten prior to the event (perhaps having an effect of an hour or less). I feel this list is stronger than the one from the DMG, since it offers a price for what's available and the method by which is it stored.
There are a number of spell components included in the list - not because I am interested in using spell components, but because I feel these are important items to have if the player wishes to write and additional spell into their spellbook, or research a similar spell for creation, or even to create a scroll - which I think should require components even if normal casting of the spell does not. The various prices are based upon real world commodities, tweaked in workmanship or by the cost of preparation. For example, the cost of the eyeballs is based upon the cost of a human slave, since one living person would need to be sacrificed in order to obtain both eyes. The slave price serves as a stand-in for the bother or danger of even creeping up on just anyone and committing murder for the sake of their ocular organs. These dangers must be reflected in the price.
Some of the items are stolen outright from 3rd edition equipment lists: gripcolle and quicksilver, for instance. I'm not above stealing if the idea is good.
There are two interesting potions that exist in actual alchemy. Blue mass was a medicine created and sold in the 19th century (but is too interesting not to include in my 17th century world) which contained mercury, but was nevertheless used to treat tuberculosis, constipation, toothache, parasitic infestations and pain resulting from childbirth. It was ingested, although of course mercury is quite toxic.
The other, Four Thieves' Vinegar, is a plague remedy dating from the Middle Ages. Wikipedia does not do the subject justice, particularly as it does not include the recipe, which can be found here. It is less likely to kill you, although wormwood is a critical ingredient of absinthe, which will eventually cause some rot to your brain. Undistilled, however, wormwood is less harmful.
I apologize for not including this discussion when I first posted. In future I shall try to include more commentary on the equipment lists as I post them.
