I'm writing a fantasy novel titled "Seraphim Divided." In the novel, there is a god known as Thorolax (The Midnight Harbinger). I want to have him be introduced as an ethereal being who has to rely on influence more than direct confrontation. As the story goes on, I was thinking he should inhabit the body of a race known as the Ladin Puratel — as human bodies are not strong enough.
What are the pros and cons for my goals of these two scenarios? (A) Have powerful magic when possessing the body of a L. Puratel and weak magic in spirit form. (B) Have weak magic when possessing a L. Puratel but powerful magic in spirit form.
