Eureka! It's a Gold Chest! In a Magic Store!

There's the gold chest we'd been looking for!

In the first step (

) we learned that some presets are good at making people but terrible at making objects.

In the second step (

) we got into the magic shop but nowhere near the gold chest because the prompt started out talking about the magic shop.

This one starts with a preset that uses artists who do inanimate objects, then the wording starts with the most important thing (the chest) and adds the other details afterward. And voila!

Just stuff I wish I'd known when I was starting out.
