All wizard spells belong to one or more schools of magic. A school
of magic represents related spells with common features or characteristics.
For a mage, who is the basic or general wizard, the school of
a spell doesn’t matter too much; he can learn and cast any spell
without regard to the spell’s school. The only exception to this
rule is wild magic, which is completely unfathomable to any wizard
except a wild mage.
While the majority of wizards are mages, a significant number
choose to be specialists who concentrate their efforts in one
particular school. Generally, this increases the wizard’s abilities
within the school of his choice at the cost of losing access to
any schools with opposing philosophies.
