Legend
I want D&D style magic. I don't want the older brother from Onward or the Ancient One from Dr. Strange explaining how and why it works.
That's what I mean about it just happening. There's no in world explantation for swinging a sword, so no prattle about why magic works
Having just watched Onward this past week, I want to disagree with you about that one. Not in the presentation (we don't need a nerdy older brother) but in the mechanics.
"Speak from your heart's fire" is nonsense, if it means anything it means "say it with intent and desire". Then the rest is just concentrate, believe in yourself, and make sure you hold the staff.
How does magic work then? You say what you want to happen, with the intent of it happening, and focus on it happening, then it happens.
In other words, magic just happens. Which is exactly what we want, but it is placed in fancy language to make it seem more special.
