I am looking at an Undying Light Patron Pact of the Blade Warlock or a Favored Soul Sorcerous Origin Sorcerer, probably with the War Domain. Either way, I would start with a level of fighter and take the Great Weapon Fighting Style, usually using a maul, and using the new Green Flame Blade Cantrip. Which of these do you think would make the better gish character? Any other suggestions? Thanks!
