“Heroes WOW” is a custom 3.3.5a server, with more races of which allows you the game itself. there is a tutorial to unlock races and play with them as the nagas, the Vrykul, ogres, etc…?
Greetings.
Even if this was a proper question for help and support (which it is not) we can’t help with this, as it would likely require client edits we don’t support at all, plus, advertising for illegal public servers isn’t allowed, either.
