Spell Familiarity [General]

Through long practice, you have become so intimately familiar with a spell that you can cast it at will.
Prerequisite:  Arcane caster level 3+
Benefit: Choose one cantrip from your spell list.  You may now use that spell as a spell-like ability an unlimited number of times per day.  If this spell was chosen from a sorcerer or bard list, you may replace it with a new cantrip in the list of spells you know.
Special:  You may take this feat multiple times.  Each time you take this feat, you choose an additional cantrip to use as a spell-like ability.
Special: A wizard may select Spell Familiarity as one of his wizard bonus feats.
