Specialist Wizards concentrate their efforts into a single discipline – kind of. See the thing to remember about Specialist Wizards is that they aren’t cut and dried. There are five Specialist Wizards who concentrate on a single school (Abjurer, Diviner, Illusionist, Necromancer, and Transmuter) and three that concentrate on two schools (Conjurer, Enchanter, and Invoker). What’s more, there are only a few races who can even specialize besides the Human which means that if you want to really push yourself into a specialized direction you’re going to have to think about where you want to be from the moment you qualify as a Wizard.
One of the things that I find fascinating about Opposition Schools is that they aren’t quite what I expected them to be when I initially looked at the graphic. To my mind it appeared that only the schools directly across from each other would be opposed, however, that isn’t the case because any school next to an opposed school may also be opposed by the same school.
If you look at the above illustration of the spell schools you’ll notice that Illusion is directly across from Necromancy which means that the two schools are also opposed to each other; however, Illusion is also opposed by Abjuration and Invocation / Evocation. Necromancy, on the other hand, is opposed only by Illusion and Enchantment / Charm.
I’m not entirely satisfied with the way that these schools oppose each other because intellectually I’m struggling with the “why” of the opposition and I need to do more research here in the future but for now it’s enough to simply acknowledge that this is the case and move on.
On pages 45 – 46 are a listing of the 5 bonuses and negatives to playing a Specialist Wizard. I’ll need to refer back to this when making the character later.
