Edit: this is for a sorcerer in my AL game.
He has 2 lvls of paladin and is going to be a up close fighter primarily using booming blade. Just a fun thing im trying. But hes mainly going to be a spellcaster.
My idea was to use a greatsword with booming blade. At lvl 5 it automatically does an extra d6 with the initial attack.
Before attacking I use Thunderous Smite as a bonus action and then if i hit i use Divine smite (not actually casting a spell. All together im looking at 7-9d6 damage for one attack.
However it involves 2 1st lvl spell slots every time. Thats why i wanna maximize the 1st lvl slots.
I know I could probably just go full paladin but i still wanna be able to do other spells if i have to like fireball or invisibility.
Just bear in mind that Divine Smite specifically requires Paladin spell slots. That works with multiclassing, but it won't necessarily work with slots acquired by other means.
