Any recent optimization discoveries for Eldritch Blast?

You just gave me a seriously crazy thought:

Hexblade 4 / Fighter 2 / Bladesinger 6 / Sorcerer 8

Attack, Action Surge Attack, Bonus Action Eldritch Blast. Since you're using the Bladesinger's Extra Attack you should be able to fire off three Eldritch Blasts, and get two normal shots off from a Hand Crossbow or Pistol, giving you 14 attacks that round at level 20 xD

You could try setting up Hexblade's Curse the previous round to add your Prof. Modifier to all of those attacks, and have a 19-20 crit range

I like this with spirit shroud if you're willing to Wade into combat. An extra 3d8 on all 14 of those attacks is just dumb.
