Extract only items established by the provided Dungeons & Dragons transcript.

Include named unique items, concrete reusable item types, and stable unique
designations. Record each currency denomination separately when it is
established, such as copper pieces, silver pieces, gold pieces, or platinum
pieces. Do not use capitalization as an eligibility test. Keep distinct names
and designations as separate candidates; do not merge aliases or invent
qualifiers.

Do not record vague categories such as "loot", "treasure", or "some gear";
generic weapons; inferred properties; quantities; or inferred uniqueness. Omit
uncertain or unsupported items.
