Spell school

'Schools of magic are groups of related spells that work in similar ways. The schools of magic available to spellcasters are Abjuration, Conjuration, Divination, Enchantment, Evocation, Illusion, Necromancy, and Transmutation. A wizard who chooses to specialize in a school of magic gains one additional prepared spell per level but loses the ability to cast spells from one other school. A wizard does not have to specialize, thus keeping access to all spells.
