Your familiar continues to gain in power as you advance your mystical talents, and it gains the ability to use some minor divination magic.
Benefit: Your levels in the mystic theurge class count as levels of a class which continue to advance the power of your familiar. Additionally, your familiar gains the ability to cast spells from the following list a number of times per day equal to your Wisdom modifier: detect magic, detect chaos, detect evil, detect good, detect law, and true strike. The save DC is equal to 10 + your Wisdom modifier + the level of the spell.
