Base Class: Bard
Whether it be due to nefarious materialism, a massive ego, or supremely misplaced self confidence, these bards can speak and act with unreasonable and unquestionable assurance, sometimes even displacing or discrediting true experts in the field.
The name itself is a product of sarcastic derision from other bards. There is no actual location or organization called the College of Bullshit, and any gathering of such like-minded bards would quickly degenerate into either a circle of self and mutual ingratiation, or an explosive clash of egos.
