White Mask

When worn, the mask confers the ability to alter your appearance at will similar to the disguise self spell as a free action. Additionally, the disguise is so accurate that you can perfectly mimic the appearance of any humanoid of similar size you have seen within the last hour. The longer since you last saw the target you are mimicking, the less accurate the disguise. However, if it is a disguise you have frequently taken, you can consider the mimicry to be near perfect. This is still an illusory effect, though for purposes of dispelling and breaking, treat it as a 7th level spell cast by a 15th level caster. The appearance change doesn’t have a duration.
The wearer can also assume whatever alignment he wishes to be perceived as for all magical effects such as detection and protection from spells.
The mask also gives the wearer a +10 on any check to mimic another’s voice. Once per day, you can use the mask to cast True Seeing as if cast by a 15th level caster
