Empath

You can use either Perception or Sense Motive when reading an emotion aura with the read aura occult skill unlock. Reading a creature's emotion aura takes you only a full-round action instead of 10 minutes, and if you succeed at your check, you also determine whether that creature is currently affected by a fear or mind-affecting effect and the relative strength of that effect (minor, moderate, strong, as defined in detect magic). You don't learn the source of the effect or the actual effect. You can also use the read aura occult skill unlock to read emotion auras more than once per day by opening your innate mental defenses. For 1 minute after you use this feat, you take a -4 penalty on saving throws against fear and mind-affecting effects (regardless of whether you succeeded at the check). During this time, you're also unable to attempt to read emotion auras. Using this feat doesn't use up your one daily use of the read aura unlock, which you can still use either to read another type of aura or to read an emotion aura without taking the penalty associated with this feat.
