Wharton professor Ethan Mollick showcased an interactive site built with GPT-6: "The Underdark Duel," a D&D 5E (2014 rules) combat simulator pitting a Mind Flayer (71 HP/AC 15) against a Drow warrior (150 HP/AC 18). Every roll is recorded, with seed-based reproducibility and downloadable combat logs. He checked the rules and found no major errors, though the Mind Flayer's tactics could have been more creative.
