Your study of the divine has given you inspiration for your performances as well as additional mystical powers.
Benefit: Your levels in mystic theurge count as levels of bard for purposes of determining how many times you are able to use your bardic performance ability per day and what type of action it takes to begin a bardic performance. In addition, once per day you can use your bardic performance ability to imitate the effects of a detect chaos, detect evil, detect good, or detect law spell. It lasts as long as you continue to perform. Your caster level for this effect is equal to your bard caster level, and the save DC is equal to 11 + your Wisdom modifier.
