These were deities for a homebrew campaign, and the DM had already provided their domain, element, and symbol (i.e. war, fire, stallion). I usually just generate 4 images at a time (only takes a few seconds on a 3090) and pick the one I like the best. Sometimes I'll generate 2-3 sets of 4, but not often if I don't have a clear idea of exactly what I'm looking for.
If it's something really specific I need, I could spend hours using in painting
and various noise/models to get what I want.
Edit: oops, I was thinking of a different montage I did recently: https://pixelfed.social/i/web/post/595611323719481231
The previous linked image was much the same process, though the prompts were more detailed as the other players had provided more information on their character's appearance.
