Are Assassins the only Class/Archetype capable of creating fake identities? I know that the Charlatan Background grants you a False Identity with the proper identification to establish it as real, but as for creating more False Identities it would seem as if the Assassin's Infiltration Expertise ability is the only way to do so, with the cost of 25gp and 7 days of work.
The character I am working on is a Bard with the Charlatan background that uses their Disguise Kit and the Disguise Self spell in order to be assume numerous different identities. These are identities that they would use regularly depending on the occasion. Now, this is usually just a simple "use Deception to convince them you are who you say you are for the moment," but I was wondering if there is a way for my character to establish credibility for these other identities in the same way the False Identity feature is set up?
I don't want to have to put 9 Levels into Rogue just to add credibility to new identities, so I was wondering if their is any way for my character to attempt the same thing the Infiltration Expertise ability allows, however, obviously, not as effectively or efficiently, such as a higher gold cost and more time spent to establish credibility?
