Staring back at myself

Sometimes I just have to stare something in the face long enough before I can see it.

Sorcery is Arcane.  Ritualism is Divine.  The four schools that were under each are combined into one skill.

Is this a perfect balance?  Well, no.  Transmutation as a spell group has always dominated the list by the sheer number of spells it has.  As it is, I'll be going through the Arcana Unearthed spells and redistributing them as I feel appropriate.  Because I can do that.  And I'll probably add in a few here and there that I really liked the flavor of (probably a good deal from the Arcanis system).  And I'll remove the typical summoning spells, replacing them with my preferred one-shot summons, and that by itself should help balance between the two groupings.

Spellcraft as a skill would allow access to more complex magics from the other magical discipline (skill in either discipline would give access to the simple spells from any school).  Exotic spells from your own discipline could be learned at ranks 3, 6, and 9, and more could be learned (from either discipline) through the use of Combat Proficiencies.

Unrelated quick thought: Base exotic weapon proficiency on a new Weaponmaster skill - each rank gives access to the exotic weapons of a different basic group (polearms, heavy blades, etc.), chosen by the player upon placing points in the skill.
