Hello. I recently created a magic item and my player wants to use it as their bonus action off hand/dual wield attack. I went to the customs tab but don't see the option to set it as an off hand attack so that they don't add their modifier to the damage. Is there a way to fix this or can magic items not be set to off hand attacks?

Thanks. 

If the Character does not have the Dual Wielder feat, then only light weapons can be used for Two Weapon fighting.

Thank you. That makes total sense. I didn't think about that.
