These humanoids resemble hairless, genderless humes with no facial features and grey skin that changes color, allowing them to blend perfectly with their surroundings.

Critical Attack (Ex)
Once every 1d4 rounds as a standard action, the faceless can inflict more pain than normal. If they succeed at hitting with their shortsword attack, the damage is 1d6+2 plus another 1d6+2 divided by half.
Shadow Blink (Su)
The faceless can teleport adjacently to any creature within 15 ft. and may attack the creature, once. This ability cannot be used while in Sunlight nor can it be used if there’s no room to teleport adjacently to the creature. This ability does not provoke attacks of opportunity. Blue mages may learn this ability as a 2nd level spell (Knowledge: Arcana DC 19).
