You've just finished downloading Wolcen and you're immediately confronted with a message that the servers are offline. If you open this news later, when the servers are no longer under maintenance, you may still be disconnected for one reason or another.
If you don't feel like waiting, a solution that won't suit everyone, but which has the merit of existing (here's looking at you, Diablo III) is to play in offline mode.
To do this, click on the button in the top right corner of the screen.
Warning: Offline characters are distinctly separated from online characters, like those in the Diablo III ladder. You won't be able to transfer them to the other category.
In addition, an offline character can't be played in multiplayer, which can be a problem depending on your preferences.
