Straight from Castle Age!
Beware 3rd Party Tools
3rd Party Tools can be dangerous.
Our official stance on the subject is for people to protect their accounts and more importantly themselves.
Third Party Tools can act as spyware on your computer to perform any number of malicious things to you beyond just in Castle Age.
Just on the Castle Age level, because we allow people to perform actions like enter emails, passwords, and more notably, change your email and password, tools have the ability to hijack your account.
To help with removing unnecessary complexity in the game, Elite Guard functionality has been removed.
