I created a GPT to answer DW questions. In my testing it's pretty good about not getting confused with DnD rules (which regular ChatGPT does). I'm organizing my first DW game as a GM and I'm planning to use it to help me out.
Some good prompts for it:
- How much XP does a character need to level up?
- How do I resolve damage from multiple NPCs attacking the character?
- Suggest 3 monsters the party might encounter in an evil wizard's castle
- Create some stats for a Giant Chihuahua monster
You do need ChatGPT Plus to use it though
I tried that at first, but I found that it would take about 2 minutes for each question to search through the PDF, which was a bit inconvenient. So I took it out added context telling it to only give information relating to Dungeon world and (crucially) to ignore all information related to DnD.
