Description is context. Context is a thing you need to communicate for the reader in the most cooperative way possible. That means, you must not lie about the thing discussed, be relevant about the thing you're discussing, write enough but not too much, and in the best possible manner in the scene..
If you say that the sword of destiny can kill everything and next scene it barely kills a goblin, you lied. The thing described must have the intended cause and effect. That works up until you're making a subversion where that thing logically does the other, for maximum effect in the story. Be truthful about the description.
If you describe a thing and then it doesn't matter for the next or current scene, you've made it irrelevant. Describe when you feel that the reader needs it the most.
If you detail every tear, every sword slash, every thing on the way in the scene, without knowing if it matters to the reader, you're breaking the quality of your story. Describing nothing that is needed to understand is the same. You need to know how long and how short the description must be to keep up the pacing and coherence of your story. Ideal description is that makes the reader understand the current scene.
If you're writing a dark fantasy story, you don't describe things like a zoomer with skibidi toilet disease, because it breaks your credibility if you describe animated skeletons that regenerate like a degenerate. You describe it like a Lovecraft, Muira, or like a competent narrator who knows what readers expect in a dark fantasy. That's the manner, knowing how to write the context knowing the meta context (genre, tone, style) and using the limitations to advantage.
It all boils down to "would the average reader who likes such stories read further without breaking immersion?" If you know what your inner reader wants, description will be easy, because that's what your inner reader wants to read. To make description is to make a world, and knowing what world you want is the way to go. Read more and develop a taste.
