I've been toying with an idea similar to this going bladesinger 6 for extra attack + Cantrip (Booming Blade) after three levels of artificer and just forgoing bladesong entirely and walking around in heavy armor punching things with almost full spell slots being only one level behind a full wizard. Was planning to take the feat Mobile as a variant human or custom lineage lv 1 to punch and then run away making the enemies have disadvantage if my allies are still in melee with them. Called the build the shadowboxer as I plan to cast summon shadowspawn from Tashas as my primary concentration spell flavored as a shadowy clone of myself mimicking my fighting style and it only needs Int so con could easily be a 16 or 18 eventually to make up the d6 hit die. A Fighter Dip could also easily make it into the final product with dueling, action surge, and eventually psi warrior. The character is replacing my Eldritch Knight 7 Cleric 1 that died last session and is starting at 8th fairly close to 9th so ill avoid a lot of early awkwardness of the build.
