True Form (Ex)
At 7th level, a chosen one’s familiar reveals its true form, transforming into an outsider improved familiar that matches the chosen one’s patron’s alignment (typically an arbiter, a cassisian, a harbinger, or a silvanshee, but potentially any lawful neutral, lawful good, or neutral good outsider familiar depending on the patron). The familiar gains the change shape universal monster ability if it doesn’t already have it, which it can use at will to transform into its original form or back to its true form.
