New build:

Race: Human

Class: Fighter

Background: Noble

Specialty: Magic-User

Fighting Style: Dualist

Primary stats of Intelligence and Dexerity.

Any melee finesse it doesn't matter as by level 3 most attacks will be a combo of shocking grasp and jabbing (with deadly strike stacked on).

still tough, can parry attacks as well.

Maybe use the rapier that comes with dualist.
