You can change your appearance to that of another individual with ease.
Prerequisites
Monstrous Bloodline (Doppleganger).
Benefit
You can change shape as a supernatural ability. This functions as the alter self spell, except that you do not adjust your ability scores. The caster level is equal to your total Hit Dice, and you can use it a number of times per day equal to your bloodline level + the number of Monstrous Blood feats you possess. The save DC is based on your Charisma.
You can use this ability to assume the appearance of specific individuals and gain a bonus on the Deception check to disguise yourself as that individual equal to your bloodline level.
