There’s a thing I heard somewhere about how your magical system needs to have a balance between how well it’s understood vs. how useful it is, or else it will break the plot.
If a magic system is extremely useful, then it must also be extremely mysterious, so that you can say “Well, it can’t immediately fix all problems because the gods work in mysterious ways.” Gandalf or Tom Bombadil seem incredibly powerful, but they don’t solve all of the problems in Middle Earth, and that’s okay because they’re terribly mysterious.
If a magic system is extremely well understood in-universe, then it has to have hard limits on how useful it is, so you can say something like “Well, the Law of Equivalent Exchange says that to solve all our problems would require a blood sacrifice of the entire population, so that’s not an option.”
If your magic is pretty well-understood AND very useful, then by all rights it OUGHT to solve all your problems, and when it doesn’t then readers rightly begin to question why any of the plot needs to happen at all (see, for example, the time turners in Harry Potter).
