Pantalone, aka The Regrator, is the 9th of the 11 Harbingers. A businessman, Pantalone oversees the budget and expenses of the Fatui. He is also in charge of the Northland Bank. He hides his insecurities by flaunting his wealth. So if you manage to get him to drop the "rich-guy" persona, then that means he trusts you enough to be himself around you.
