And the magic he used was never smoothly blended with his combat abilities but rather just something he knew from his mage apprenticeship. Mouser is definitely not a great example, since, as described in the books, it seemed much more like he multi-classed rather than was developing any sort of combined class. And as for Fafhrd and the Grey Mouser, the first one does not use magic and the other one is more of a rogue anyway, his magic is very simple. Rand al'Thor almost never mixes either, and we have to wait until almost the end to see Demandred do it, and only when pressed. Elric rarely mixes the two, as his incantations are powerful and you can't hardly boost Stormbringer anyway, and he uses potions and alchemy too boost his body. While a number of these might be a combination of fighting and magic, there is actually very little blend between the two. OK, I was going to suggest the same thing (although part of me screams that it's wrong), starting from the mechanics, because in that other thread, when I suggested going back to the fantasy genre roots, made suggestions that I found not very appropriate, for example Rand al'Thor, Elric of Melnibone, Jirel of Joiry, and Fafhrd and the Grey Mouser. It can be done with subclasses or multiclassing sure, but to see a class with its own mechanics around the concept is preferable. For Sword Burst to be truly effective, you have to be focused on more than just being a melee caster you have to be somewhat of a tank. Eldritch Knight Fighters, Hexblade Warlocks, and Bladesinging Wizards come to mind.

They studied both the blade and the eldritch arts, in order to combine the two. Here are a few ways to use Sword Burst in DnD 5e: Go for a gish build. More around studying and using arcane magic as opposed to like the paladin gaining power through an oatyh and following it, using divine magic, or a ranger gaining more primal or nature bases magic through their bond with nature.
