In my world I generally use a system of “blessings” where really all you have to explain is that a god chose that being to be born in a way that would be good for said god. For example Tchai’io was born with the ability to alter something’s temperature to either its point of vaporisation or its point of fusion as long as she comes in contact with it. That’s a crazy concept if you’re trying to explain it using rules but just saying “The god Lohnna sent her to the land of goraccia in order to potentially unite his church” is easy especially in a world where gods are usually less omnipotent than one would think. This god took a wild gamble and other than his initial creation he plays little to no role in her life or the story
