Sorcerer's Guide to Kits
short: Specialist mages have become narrowly trained in a specific
field of magic. Specialists receive one additional spell per spell level
than unspecialized mages. Because of their specialization, these mages
receive a +15% chance to learn spells from their school but suffer a -15%
penalty when learning spells outside their specialty.
When saving against spells within his chosen school, the specialist receives a +1 to saving throws. Similarly, the specialist's enemies suffer a -1 penalty when saving against spells cast by the specialist within his field. Specialists are unable to cast spells from the opposing school.
Mages must be single-classed or dual-classed to specialize with the exception of gnomes. Gnomes can only be illusionists so are permitted to multiclass. A specialist must have a 9 intelligence in addition to the School-specific minimum ability. The prime requisites for specialty mages are intelligence and their School's ability.
Requirements: Race: Human, Wisdom: 15
Opposition School: Alteration
