I'm a level 6 Bladesinger Wizard. I have Haste cast on myself. I am wielding two shortswords. If I use my action to Cast a Spell, such as Booming Blade, and use my additional action granted by Haste to Attack, can I use the bonus action attack granted by two-weapon fighting?
I have considerations on either side. Two-weapon fighting requires you to take an Attack action. It seems that Haste grants an Attack action, but it is modified and limited, and those limits may extend to two-weapon fighting as well.
