+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.
