To earn this achievement you’ll need to compete in and win a lot of tournaments, although the precise amount will vary depending on your campaign. In general, you can expect the AI leader of the tournament scoreboard to have at least 20 - 30 victories, so you’ll need to win at least that amount to compete with them. It shouldn’t take too long once your character is tough enough to consistently compete in and win tournaments. You can check the tournament scoreboard from any arena in Calradia by visiting an arena and selecting the option to view it.
