Linguist
Pathfinder 2nd
The Linguist is a niche archetype that any character can pick up so long as they know three languages. Just by entering this archetype you gain training in the Society skill (or just rank it up one level) as well knowledge of four more languages by giving you two instances of the Multilinguist feat.
Languages tend to be a wrench that a gm will throw at a party when they want something they can't just kill their way through it, but now you can turn that into its own set of tools beyond just writing. Though none of it is offensive in nature, it does give you the ability to replicate whatever you read, impersonate a person's mannerisms after reading every detail about them and even find ways to interpret unspoken communication.
