The clerk seems markedly insulted by Iris' lowball offer. When Adalbert directly asks for the correct price to get a consultation, the clerk seems uneasy, but then names the price of 50gp. You pay and he pockets the money. You do not get a receipt. He takes another book from under the counter. This one seems less of an advertising material and more of a detailed product specification. Notably, it has the price listed for the crystal golem, assuming that is the type you are interested in, and some other notes. The baseline price is listed as 127000gp for a standard modification, the time to build one is listed as six months, and there is a mark, which the clerk explains means that the order would need the approval from the authorities. The clerk says this golem is a fairly special thing, not many of them are ordered. The golem can do psychic magic and works best for a master that also does psychic magic. A top psychic in the service of a government might get one of those, for example. The golem's largest weakness is its succebility to a fairly low-level spell, namely Shatter. It is of course, also succeptible to physical attacks made with adamantine or construct bane weapons or ammunition.
