Spell School Substitution (3.5e Feat)
From D&D Wiki
Spell School Substitution [Metamagic]
You can modify any spell school to use another type of school instead
Prerequisite: Arcane Caster, Knowledge (arcana) 10 ranks, any metamagic feat,
Benefit: Choose one type of spell school (Abjuration, Conjuration, Divination, Enchantment, Evocation, Illusion, Necromancy, or Transmutation). You can then modify any spell and use the chosen type of spell school instead. An spell school substituted spell uses a spell slot of the spell's normal level. The spell's descriptor changes to the new spell schools type—for example, a fireball composed of the spell school substitution of necromancy is an necromancy, [fire] spell.
Special: You can gain this feat multiple times, choosing a different type of spell school each time.
