Based on: charisma

When you attempt to influence someone through overt threats, hostile actions, and physical violence, the GM might ask you to make a Charisma (Intimidation) check. Examples include trying to pry information out of a prisoner, convincing street thugs to back gown from a confrontation, or using the edge of a broken bottle to convince a sneering vizier to reconsider a decision.
