Arcanometry is so hard.

Prerequisites: ability to cast arcane spells, base Knowledge (arcana) score 5

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 and caster level caps that spell might have are increased by 1.

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.
