Esoteric Magic (Ex)
At each class level beyond 1st, the Pathfinder savant chooses a spell from any class’s spell list and thereafter treats that spell as if it were on the spell list of the base spellcasting class for which he has the most levels; if this base spellcasting class could not normally cast that spell, it is treated as 1 level higher than it is on the original class’s spell list. If he could cast the spell using his base spellcasting class, the spell’s level does not increase. The spell is cast as if its type (arcane, divine, or psychic) were that of his base spellcasting class, and save DCs function as normal for spells of that class. All other restrictions of his normal spellcasting class apply. This ability does not grant other spellcasters special allowance to prepare, cast, or use spell-trigger or spell-completion items of esoteric spells (such as a sorcerer using a cure light wounds scroll prepared by the Pathfinder savant).
