From publisher blurb:
Scholar of Paletius is a 20-level based class created from the collegiat arcanist prestige class and the wizard core class.
This prestige archetype is a 1/2 base attack bonus class that excels in collecting and ultilizing magic from his catalogue of spells. Scholars of Paletius are forces of good in the Lands of Porphyra campaign setting.
It also contains favored class bonuses for races that come from the lands where Paletius has major followings, and a sample character Ulik Tomebound, a polkan scholar at levels 1, 5, 10, and 15.
