I have two sabres, both show in the information screen as being Sabre, one-handed. The character can use both sabres without issue.

Yet, one I can use a shield with, the other I cannot, yet both are sabre, one-handed.

Greetings Sylvus,

 

Thank you for informing us with your issue today If possible might you provide us with a savegame file in which you are unable to both your saber and shield?

 

Cheers.

One of the sabers in the game only works as an off hand weapon because it's also a torch. That takes up the slot a shield would use

Yes it is the glowing green one I got in the preorder package that says it is a sabre, one-handed.

That sabre is offhand only, because it's a torch.
