Benefit
Select one spell of a school for which you have taken the
Spell Focus feat. Treat your caster level as being two higher for all level-variable effects of the spell. Every time you gain an even level in the spellcasting class you chose your spell from, you can choose a new spell to replace the spell selected with this feat, and that spell becomes your specialized spell.

You can gain this feat multiple times. Its effects do not stack. Each time you take the feat, it applies to a different spell.
