I want to use two short swords but I am not sure if I can. It sounds like the Bladesong might end in the case of dual wielding:
Starting at 2nd level, you can invoke a secret magic called the Bladesong, provided that you aren’t wearing medium or heavy armor or using a shield. It graces you with supernatural speed, agility, and focus.
You can use a bonus action to start the Bladesong, which lasts for 1 minute. It ends if you are incapacitated, if you don medium or heavy armor or a shield, or if you use two hands to make an attack with a weapon. You can also dismiss the Bladesong at any time you choose (no action required).
When it describes using two hands to attack with "a weapon" that makes me think I could perhaps use two hands to attack with two weapons?
