You are able to wield as many swords as you can carry for instance you can wield three swords at a time typically, this is essentially an upgraded two-weapon fighting feat that is only limited to the number of swords you could hold at a time. When holding the number of swords you can hold instead of 1 attack as a bonus action you can attack for as many swords as you can hold with a minus to your hits equal to the swords used after the 1 as a bonus action regularly.
