You can take on the appearances of other creatures and even specific individuals. This functions as the quick disguise exploit, but the duration increases to 10 minutes per operative level. Alternatively, for 1 minute per operative level, you can take on the appearance of a specific individual that you have seen before. If you have heard the individual talk and can speak her language, you can also modulate your speech to match hers. This disguise is so convincing that creatures familiar with the individual must succeed at a Will saving throw before they can attempt a Perception check to pierce the disguise. You must have the quick disguise exploit to learn this exploit.
