At 2nd level, when an infiltrator uses disguise self or any polymorph extracts on himself, he is treated as 2 investigator levels higher for the purpose of determining the duration of that extract's effect. He can use these extracts to take the appearance of specific individuals of the form he chooses, gaining a +10 bonus on Disguise checks even if that extract does not normally grant such a bonus. Furthermore, these extracts grant the infiltrator a +10 bonus on Disguise checks that are made as part of his voice mimicry ability. This ability replaces poison resistance.
