Esquire is the second out of 13 titles in the game. It gives you an advantage over the Yeoman.
From the moment you are given the title, the amount of XP and EGO earned in the game is multiplied by a factor of 1.3. In other words, you start earning XP and EGO 30% faster.
Your Daily Tribute and Faction Tribute become 1.3 times as much.
You can become an Esquire one of the following ways:
There is a risk If you have become an Esquire by accumulating the stake and then your stake in EGO drops below 5,000,000.
You will be informed if one of the risk factors occurs. You will have at least 48 hours to meet the requirements. If you don't meet them you might become a Yeoman or a Commoner. That depends on your EGO balance.
If you get the Noble Title of Esquire as a reward for completing a special quest your title will be assigned to you for life.
If not, make sure your EGO balance is well above 5,000,000 Ego. This way you will significantly reduce the risk of losing it.
