Spell Focus

You love this ONE spell a little too much. 

• Choose a spell that you know and can cast to be your specialized spell. If you prepare spells, then this spell must always be prepared. When casting this spell, treat your caster level as being 2 levels 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 may take this feat multiple times. Its effects do not stack. Each time you take this feat, it applies to a different spell.
