Legend Lore
Name or describe a famous person, place, or object. The spell brings to your mind a brief summary of the significant lore about that famous thing, as described by the DM.
The lore might consist of important details, amusing revelations, or even secret lore that has never been widely known. The more information you already know about the thing, the more precise and detailed the information you receive is. That information is accurate but might be couched in figurative language or poetry, as determined by the DM.
If the famous thing you chose isn't actually famous, you hear sad musical notes played on a trombone, and the spell fails.
Legend Lore 5e 2024 vs. 2014 edition differences
The 2024 version specifies "famous" person, place, or object, and that the DM determines the nature of the lore, including figurative language or poetry. It introduces a failure condition if the chosen thing isn't famous, whereas the 2014 version does not specify fame or failure conditions.
