Changelings (by DracoDruid)

Changeling Racial Traits
+2 to One Ability Score : Changelings get a +2 bonus to one ability score of their choice at creation to represent their varied nature.

Manipulative: Changelings receive a +2 racial bonus on Bluff and Intimidate skill checks.

Minor Change Shape (Su): Changelings have the supernatural ability to alter their appearance as though using a  disguise self  spell that affects their bodies but not their possessions. This ability is not an illusory effect, but a minor physical alteration of a changeling's facial features, skin color and texture, and size, within the limits described for the spell. A changeling can use this ability at will, and the alteration lasts until she changes her shape again. A changeling reverts to her natural form when killed and a  true seeing  spell reveals her natural form. When using this ability to create a disguise, a changeling receives a +10 circumstance bonus on Disguise checks. Using this ability is a full-round action.

Starting Languages: Changelings begin play speaking Common.

Design Commentary
This was pretty strait forward. I simply gave them Darkvision and a standard ability bonus and called it a day.

Recently, I added Living behind a Mask.
