The Adviser doesn’t have any power over anyone like The Prince/Princess or Knights. Their main purpose is in the title, they assist and advise the Acting Prince/Princess when needed. But they can also act as a messenger between the Head of House, Acting Prince/Princess and Knights. They always start as the person who came second in the duel for Acting Prince/Princess BUT the Acting Prince/Princess has the right to declare them unfit after two months, this usually only happens if the Adviser is sour about losing and isn’t actually helping, or it is known someone else would be better for the job.
