## Arcane Thesis You have studied a single spell in-depth. Your expertise grants you formidable though narrowly focused arcane mastery. **Prerequisite:** Spellcraft 9 ranks, at least two metamagic feats **Benefit:** Choose one arcane spell that you can cast to be your thesis spell. When casting that spell, you do so at +1 caster level. When you apply a metamagic feat other than [[Heighten Spell]] to that spell, the enhanced spell uses up a spell slot one level lower than normal. **Special:** You can gain this feat multiple times. Its effects do not stack. Each time you take the feat, it applies to a new spell.
