You have worked hard to create believable alternate roles for yourself.
Prerequisite: Disguise 2 ranks.
Benefit: You have a number of well-established personas other than your own identity. These are roles you have crafted and maintained back stories for, with lists of contacts and documentation of events in the personas’ lives (such as guild membership, paying taxes, doing business, and so on). You have used these personas often enough that inquiries into them will find people who know only the persona, and will confirm they exist as real people. You gain a +4 bonus to all Bluff and Disguise checks to pass as an established persona, and to Linguistics check to make forgeries in support of the persona. This bonus increases to +6 at 10th level.
You must keep a list of your personas, and each requires GM approval. You have one established persona for every 2 levels or hit dice you possess. You may replace an existing persona with a new one (losing the benefits of this feat for you old persona, as you no longer maintain it) once at every odd-numbered level.
