Similar to Maneuvers, there's a general list of schools, and one specialty school per class.

This is more permissive than 5e, S6, etc.

All schools exist in one list, but each class is either advantaged, neutral, or disadvantaged (not the final terms), where:

• Advantaged: better at casting, gain extra spells not available to others, baseline spells improved
• Neutral: cast as written
• Disadvantaged: can't cast at all, except rituals; or perhaps cast at half level or something

More complex than A, but helps to preserve class identity better.\

Take it down to the granularity level of spheres, not schools.

This sounds complicated.

Everyone has their own spell list.
