The Shadow
Hero
As far as I'm concerned, the spell schools can die in a fire. They're either too narrow (Abjuration) or too broad (Transmutation), and almost completely flavorless.
Wizard specialties should have more pop to them than that. Some possibilities:
Beguiler: Illusions, mind-affecting magics, shadow magics, and so on. (The 1e Illusionist did so much more than illusions!)
Elementalist: Elemental damage, sure, but also summons, defenses, and so on. Even sensory powers - a fire mage could do Darkvision, an earth mage tremorsense, and so on.
Necromancer: Undead, yes, but also curses, diseases, draining, and so on. Perhaps just a bit of healing.
Diabolist: Summons, more curses, hellfire, and so forth. (This one might be stepping on the Warlock a bit, but the scholarly diabolist is definitely a Thing, legendarily-speaking.)
Thaumaturge: Flashy whiz-bang magic: Force spells, polymorphs, other kinds of transmutations. Not a lot in terms of direct damage.
The trouble is that to really make these work, they'd need restricted spell lists, which is not something One seems to be going in for. Or else we'd need to create new "schools" from scratch.
