Does that mean you can't get a +6 to Ac fro duel wielding rapiers, would it work for 2 different weapons, like rapier and scimitar

Sorry the defender sword, would a scimitar version and short sword version allow you to effectively get a +6 to Ac while duel wielding

You can't attune to more than one copy of the same magic item. See DMG 136 and 138. #DnD https://t.co/GQB8UHKOAL
