How about we continue the spells for DnD 5e and the Eldritch Knight?
Let’s keep building on the them of the Eldritch Knight. How about some weapon based spells for above 0-level?
Casting Time: 1 action
Range: 30 feet or touch
Components: V, S, M (a weapon)
Choose a target in range, and either make a melee spell attack roll or a ranged spell attack roll. On a hit, the target takes damage equal to the weapon’s damage plus your spellcasting ability modifier as you throw or strike the target with the weapon. Next, the creature must make a Dexterity saving throw. On a failure, lightning shoots from the sky and does target takes 4d6 lightning damage. On a success, the spell fails, but the spell slot is not used. In either case, the weapon returns to your hand.
