Writing

Outside of combat, I have very little that needs to be described in that much detail. I do have one specific mechanism in my Living Dungeon story that I felt needed that level of detail, and the description went through a few edits to fine-tune it to communicate the idea accurately but keep the writing clean enough to not be jarring to the reader. I am fortunate enough to be able to get some feedback to help me in that process. I felt that this mechanism needed to be accurate because it is relevant at several points in the story.

The less relevant it is to story beats, the less I am worried about specific details. I have a second mechanism involving large colored, glowing crystals in a ceiling. I described the basic layout and the colors, because they were relevant to events in that room, I did not describe the shape of the crystals, because it doesn't matter.

In combat, how much detail I go into depends on the fight. Less important/low-stakes fights get more of an overview. A duel or spar with setup and some emotional charge? I am getting down to blow-by-blow, especially if I want to show the progression of a character's skill or power, and when getting that detailed I often need to specify which hand a person is using to do what, so that I can line up the action properly.

A right-handed person has a shield in her left hand, and therefore deflects a creature's charge to her left, and is thus spinning left to slash her axe across the back of its leg. I could have described it as her spinning counter-clockwise, which would be more technically accurate but would pull the reader out of the story more to think about. 'spinning left' suffices.

So, I would mostly just try to be sure that it needs to be described in detail.
