Thank you for the prompt, that's very useful! I'm surprised GPT "knows" what Monster of the Week is. RPGs in general are somewhat obscure, and to ask for a specific one at that?
In fact, it's SO knowledgeable, that if you tell it to talk in the accent and slang of people from Sigil, the feature city in the Planescape D&D Setting from the 90s, it will perfectly adopt the character.
