The Nickname perk allows for you to give yourself a nickname using the /nick command. This includes item names in standard colors, hex colors, and gradients.
Note that this perk is already fully provided in the Seraph rank.
How to Use
Enter the command /nick
You also can use a gradient of colors, specifying key colors (separated by commas) to be part of the gradient. This can be done using /nick gradient color1,color2,... <name>
For example: /nick gradient #FF0000,#00FF00,#0000FF MyNickname
You can additionally make the text be bold by using the gradientbold keyword instead of gradient.
The name can be removed by simply running /nick.
