S6 Spell Schools

The idea:

Basically, the spheres should be kind of like 5e domains. 2 spells/level max, plus rituals, maybe a special power or two.
Each sphere has its "core spells". Anybody who "has" the sphere knows all of those.
A sphere can have "optional spells". They aren't automatic, but can be learned.
All spellcasters (except wizards) have a Spell Knowledge attribute equal to level + Int. This is how many optional spells they know.
All spellcasters (except wizards) have a certain number of Sphere they "have", giving them automatic knowledge.
- For example, Clerics call them "Domains" and select them from a menu limited by their deity's alignment.
- Druids have a fixed set, based on their Ethos.
- Sorcerers choose whichever they please, but gain few of them overall.
Wizards have no in-built spheres, but have more Spell Knowledge, and can learn the in-built and optional spells from almost any Sphere.

(4) Fire Shield: Touch, concentration; enemies who touch subject (such as with melee attacks) suffer heavy fire damage and must pass a Con save to continue with their touch.
(5) Chaos Bolt: Long range; subject suffers heavy critical chaos damage.
