I feel like I've seen something like that somewhere. Gaining advantage on all magic saves if you cast a spell feels familiar. Increase damage but decrease number of targets. Blade Magic is a lot like the Magus in Pathfinder - you charge your weapon with the spell and the target of your weapon attack also gets the spell.
Unsure about Extra Attack with that spell progression. I'd drop it down to ranger status.Ībilities don't seem too bad. Spells known is stronger than a ranger but weaker than a sorc. Same spell progression as a cleric similar armor proficiencies.
