Chat bots seem to have huge issues keeping the different editions and systems of D&D apart. My players often use AI assistance to get clarity on rules, but both Gemini and ChatGPT often try sell them a 4e house rule or a bard spell from a video game as official 2nd edition. One chat bot even invented a fictional reference from an existing book that I however had as a PDF and could fact check.
There's 1e D&D from 1977, but there's also
Advanced Dungeons & Dragons with two editions (1977 & 1989) which are generally referred to as first and second edition. In a way, Wizards of the Coast dropped AD&D and instead continued D&D with their more simplified rules. I was referring to second edition AD&D, where low intelligence makes it more likely for your spells to fail and also lowers the number of spells you can learn in total. If you would fall below the prerequisite intelligence of 9 for the Wizard class, you would lose your ability to cast spells. You can find the table
here.
