- Created character sheet for me, at desired level with spells and abilities
- Was able to add a cat to the game upon request
- Took hints.
- Was an outstanding writer, far better than any DM in terms of sensory descriptions and articulation
- Had to ask it to only tell 5 paragraphs at a time
- Performed combat rolls and math, all apparently correctly for a long while
- The first 20 rolls were all greater than 10, asked it give more random rolls and it seemingly did for a while
- Added elements on the fly consistently without losing track mostly
- Used puzzles and challenges and created a sense of danger. Adapted well on the fly to unusual character behavior (guessing an unreasonable answer for a puzzle solution).
- After a few hours it started confusing classes in my party (I think there is some context window). It forgot I had agonizing blast after a few hours.
- Sometimes fudged distances
Overall for a DM with infinite patience and an entirely customizable campaign on the fly with no need to plan/recover it seems promising at first. But some sort of prompt engineering will eventually prove necessary i think.
