HEX color in tell-damager-list
Hello, I modified the boss's name with MiniMessage, setting it to <#5c330a>
What MC version are you on? I'm on Spigot 1.21.3, used tell-damagers-list <#5c330a><bold>Duvil|&r&c{order} &7- &f{damager} &7- &c{damage}
The only thing not working is the alignment when the name is bold, because that is unsupported.

I'm on purple 1.21.1 From what I see in your image, the name of the boss is seen in red, I think it would not be working correctly for you, since the hex color is brown
Thanks, will be fixed. I also got rid of the ----- line so now you can customize the header completely
I recommend you use {boss_alias} instead of hardcoding the boss name.
