True Seeing

At 3rd level, and every two levels thereafter, a sorcerer learns an additional spell, derived from her bloodline. These spells are in addition to the number of spells given at new levels. True Seeing: You confer on the subject the ability to see all things as they actually are. The subject sees through normal and magical darkness, notices secret doors hidden by magic, sees the exact locations of creatures or objects under blur or displacement effects, sees invisible creatures or objects normally, sees through illusions, and sees the true form of polymorphed, changed, or transmuted things.
