On UO: Depths you can be awarded several reward titles for different acomplishments.
To access the Reward Title menu just click your character and choose "Select Reward Title" on the context menu.





When you are eligible to show a title in your tooltip a button will appear next to the title.
Each title have several tiers, each one meaning a certain value.

For example, you can show your current title in a certain virtue and once you get the last title in all available virtues you become eligible for the Knight of Virtue title.

There are titles for the Champions, the Harrower and some quests can even reward you a title, such as the Quest given in the entrance of Destard.
