I just can´t help but think that having Schools Specialization would be really cool, for one because it could introduce more differentiation in Magus abilities, but also because it establishes more continuity with Wizards themselves... Like Inquisitors (and Domain Paladins) get Cleric Domains.
(re-posting from the ´Ki Pool´ thread)
Besides the School Abilities (and Bonus Spells???) that Wizards get, each School (incl. Universal) could have UNIQUE Magus powers associated with each school. I would say that Oracle Revelations could be a model for some of these abilities... Also there could be Arcana that simply have the Pre-Req of having a given School Specializaion. Whether or not they get Bonus Spells is probably something that could go either way...
Assuming a ´Ki Point´ mechanism like Monks, I could see this affecting their ´reserve´ Ki ability (alternate usage they can switch at will, or additional effect?) ... And WHY NOT, giving them unique usages/options for EXPENDING their Ki Points in the first place. (i.e. like Cleric Domains give Bonus Spell Choices expanding the spell repertoire in different directions).
...Also (this isn´t necessarily Specialization specific)
What about ´lingering´ effects when they DO cast a spell, i.e. a bonus to X effect for 1(?) round, whose effect depends on the school of magic they just cast? (would adding a quickend spell give two effects? or would quickened spells not count for this? or just give you the choice of either 1 or the other school?)
School Specialization could also modify/enhance the effects of these lingering effects when you cast a spell within your specialty... Perhaps´opposed schools´´ spells would not trigger the lingering effect because your knowledge of that school isn´t as deep...?
Idea: Scaling Hand of the Apprentice
enabling Full Attacks or possibly allowing the Magus to threaten a certain area at range...?
that doesn´t necessarily need to be connected to Universalist School,
it could be it´s own Arcana, but it seemed a cool idea...
