Does Duchess Work While Solo?

It’s always been part of my build and as far as I can tell works, but the BL wiki says that it doesnt work unless bound to a servant. Can anyone confirm/deny?

It works solo.
That wiki is pretty unreliable when it comes to the DLC characters for some reason, so be wary of it.

The wiki is no more accurate than people allow it to be. That’s been incorrect since the page was created.

Corrected that. Thanks.
