I might try another roleplay session once I'm done work for the day. I feel like I haven't really plumbed the depth of what it can do there.

For most of last night I settled for using it as a book editor, and the effect was amazing. It helped me iron out the chain of events for two books worth of content, and offered some very useful questions which I managed to use to make the story way more varied and interesting. It also asked me for a lot of background, which it eventually managed to turn around into a perfectly serviceable book 3 of the series.

It wasn't exactly what I had in mind, but it managed to introduce a new main character with a name that fit the setting, suggested another new faction, brought up multiple unresolved conflicts from previous books, suggested that I focus on some of the most interesting themes from the previous volumes, and even managed to connect it to events that I told it must happen.

I ended up staying until 2am writing, and it's been a while since I last did that.

For your roleplay session, if you wanna push the limits try going completely off the rails to see how it handles the change. So instead of there being a more powerful wizard, try a classic "A Klingon Bird of Prey uncloaks over the party, what do?" Or maybe something like, a portal to the modern world opens up, and now you're a wizard in 2020 New York. I find that's where it has the most trouble.
