Even though Chandelor, as a goldsmith, inherently knew way more about precious rocks than Lopus did, the court decided that it was totally fine for him to say he was selling a magical bezoar even if he'd never confirmed it had healing powers. These hard chunks of indigestible material—still often plucked from Asian porcupines for traditional medicine in modern times—were said to cure all manner of health problems, including deadly poisonings. When the poop rock in question failed to cure whatever it was that ailed Lopus, he decided it must be a fake. That wasn't really anyone's problem but Lopus's, according to the verdict: As long as Chandelor never promised in writing that the bezoar was definitely real and would definitely work, anything he wanted to fib about in the course of his sales pitch was totally fair game. The onus was on Lopus, as the buyer, to assume that Chandelor would over-promise.
