I don't think anyone is particularly familiar with the basics yet. At this point, most magic casting is accidental. Some may have put two and two together, but it's still highly experimental. Realistically, people are likely to have incorrect theories on how magic works.

That's why we're doing this more or less D&D style - you propose a mechanism of action for your spell, and I'll tell you whether it works and/or what it looks like when you cast it.
