@nprofile1q... Tbf: Some would need to have a big lore and ruleset, just like physics, to be consistent what it can do and what not.
Doing the old "just accept ist" thing might fel like the easy way out, but in many cases it keeps the pacing up und make the story more fluent.
I think the best middle ground is to include some of the rules in the lore building sections without explaingin everything in great detail. keep a hint of misteray to it, but at least make it understanable what works there.
It's like the difference between "Hot stuff can hurt you" to "The added energy makes the atoms wiggle really fast and if that wiggle gets physical contact to your skin it can change the material significantly"
I don't know if there is a "right" way to do it. Probably not, so in some cirumstances it is an okay easy way out.
